On this episode of Know How we are
going to fix your sticky Windows, your feedback, and then it’s quad copter
madness.
Father
Robert Ballecer: Welcome to Know How. It’s the twit show where we bend,
build, break and upgrade. I’m Father Robert Ballecer.
Bryan
Burnett: And I’m
Bryan Burnett.
Fr.
Robert: For the
next 45 or 60 minutes we are going to be showing you some of the projects that
we’ve been working on the last couple of weeks. We’re going to pull out
knowledge straight out of our knowledge holes.
Bryan: Oh boy. Better have a bucket ready
for that.
Fr.
Robert: Before we
do that we actually did want to talk about one story that has been making the
rounds and it is interesting.
Bryan: It is interesting. It is a kick
starter. It is 2014 and we’ve been wanting flying cars
and on that list would also be hover boards.
Fr.
Robert: We were
promised hover boards, I don’t know why we don’t yet
have them.
Bryan: It is the future, we are here. We
are waiting.
Fr.
Robert: So this
kick starter is from a company called Hendo. They
have made the first overboard. It has raised $304,338 out of 250,000 of their
original goal. 52 days ago they are already fully funded. Most of the pledges
in this kick starter will get stickers and shirts and a five minute ride on a
hover board. But once you start pledging $299 or more and can you start to
actually get the tech. It is what they call the white box developer kit. It
actually has their hovering engine. If you had $10,000 you could have gotten an
actual hover board. But they were only going to offer 10 of those and they are
already all gone.
Bryan: So we watch this video here, but
let's think about how this works. It is non-ferrous material that they are
hovering over. This basic principle has been around for a long time. The first
thing I thought of was Magnetic trains that use this. It is not like this is
something completely revolutionary.
Fr.
Robert: The
principles here are not super Earth shattering. We’ve known about magnetism and
repulsion for a long time. What they have done is a has
scaled down the cost and they've scaled down the amount of equipment that you
need to get a stable magnetic field. The problem is that if you ever put
magnets on top of each other as you try to move them along it dips and wanes
and then suddenly the field inverts. It is difficult to get a
stable field repulsion because of all the currents that happen when you
are dealing with magnetism. They figured out a very novel way of getting a
stable field. Within those currents. You need to have
a surface that is metallic, non-iron metallic. So that is kind of limiting the
usefulness. But it is still cool tech. It is still interesting. I just don’t
think it is going to be a hover board everyone thinks is going to be.
Bryan: The expectation is set to where you
could just go out in the street and have her around. That’s what I want. But I
don’t think there is going to be any skate parks or anything that have this
material laid down.
Fr.
Robert: In case
someone shows up with the $10,000 hover board.
Bryan: The point you are making too is
that on a skateboard it uses friction to help maneuver yourself.
Fr.
Robert: It gives
you lateral stability. A skateboard will move forward and back but it will not
move easily side to side. A hover board has none of that.
Bryan: The example you gave me was if you
want to experience this put oil on top of the granite countertop and try to
stand on that.
Fr.
Robert: Exactly.
You are going to be slighting, you kind of have to have your balance perfect
before you can start using it.
Bryan: We both have perfect balance. I
don’t think we've ever fallen or run into anything.
Fr.
Robert: I’ve never
tripped.
Bryan: Were pretty much athletes.
Fr.
Robert: Super
athletes. So I am just waiting for my Hendo hover
board and hopefully I’ll be able to go over water.
Bryan: You’ve gotta
have power to go over water. I was waiting for that, thank you Padre.
Fr.
Robert: Let’s take
a break and talk about our first sponsor of Know How. And of course it is lynda.com. You’ve
heard of Lynda right?
Bryan: I’ve been using it to play with
Android Studio.
Fr.
Robert: Very cool. Either
action been using it for Adobe Premier it is funny because I've been editing
with Premier for 10 years now. But, there are some things that I should have
known and maybe I did know but I’m kind of recalling
it now. You get rusty. That is what Lynda lets you do. You learn something
brand-new, or refresh your knowledge on something you already know, or it lets
you update your existing skills. Lynda Is the one-stop
shop on the Internet for knowledge. A knowledge repository, a
place to go whenever you need to update your skills or find out what is the
latest and greatest in your field. When we use lynda.com we go to the easy and affordable way to
help us learn. You can stream thousands of courses created by experts on software,
web development, graphic design and more. lynda.com Works directly
with industry experts and software companies to provide timely training, often
the same day that new versions are really least. You will always be up to
speed. All courses are produced at the highest quality, they are not like a lot
of YouTube videos which, though I love, sometimes the lighting and software the
sound is off or it is just a weird angle. You get none of that with a lynda.com course. You
get perfectly produced a video so that you can concentrate on learning rather
than nitpicking the production. Now their tools include things like searchable
transcripts and playlists, certificates of course completion which you can
publish to your LinkedIn profile so that potential employers know what you’ve

along with the instructor and premium members with an annual plan can download
courses to watch off-line, which is perfect because sometimes you are going to
be in a place where you need the reference. You need to be able to go through
that transcript and find the answer to your problem, but you are not going to
have access to the Internet. What you’re not going to have access to a fast
connection. That is why Lynda lets you download if you become a premium member.
They’ve also got multiple go pro courses including creative go pro photography
and video techniques so if, like me, you are getting into quad copters and you
are going to be mounting the go Pro learn up on that go pro first so that your
video isn’t shaky were horrible and badly framed. Now for any software that you

Bryan: if you are going to be strapping a
relatively expensive go Pro camera to a relatively expensive quad copter you
should probably learn how to fly at first.
Fr.
Robert: It is funny
because every once in a while see videos put up on YouTube and it is obviously
someone’s first couple of flights.
Bryan: Those ones are fun though. I
enjoyed watching those sometimes. Like the one where the guy goes over the
canyon and is about to run out of battery so it goes back home and fly straight
into the side of a mountain.
Fr.
Robert: The best
part about the video is they did the majestic music all the way up until it
hits the tower. Drone technology is great unless you’ve got big columns of rock
in the way. Speaking of drone technology we are going to be… this episode of
Know How is brought to you by Take Down Notices! Anyway,
lets talk a little it about Quad Copters. We got some feedback we wanted to
talk about from our Google plus group. The first one actually came to us from a
user by the name of Gilbert. He asked, “I’m glad you are doing a quad copter series
I am planning on building one. I really like the idea of buying an inexpensive
one to learn to fly on. I will probably buy the one you showed on the episode
but I have a question about it. Could I use the control for the one that I
built?” Gilbert This is actually an excellent
question. We get this a lot because you want to be able to reuse your gear. You
don’t want to just buy it once and then let it go to waste. First
of all, congratulations on deciding to buy a trainer. They are fun, they
are almost indestructible, and they will teach you how to fly a quad copter.
This is the remote that comes with the quad copter. It is not a bad remote, it
is a six channel and it is actually quite nice. This is a six channel that I am
using for our belt. It is not super expensive that it is a bit heftier and it
does have a few more options than the other one.
Bryan: And we use this for her lunchbox to
do in week?
Fr.
Robert: Yes. Here
is the problem. If you get one of these trainers that board in the center is
really the only electronics that are in there. You’ve got that in the four
motors. Now that one board has the receiver, it has the flight controller and
it has the electronic speed controllers. Which means there is
no way to separate the receiver unit from that central unit to be able to reuse
this controller. It doesn’t work. And it’s not going to bind you with
the different receiver. So, it would be great if you could but it is not going
to work. The other thing is this remote is going to top out at around 300 feet.
Once you get 300 feet away you start getting weird things happening. The Fly
Sky and some of the dedicated controllers will go much further and they
actually have a homing procedure where the receiver loses its signal it will
actually try to start coming back. If you go out of signal with the other one
it will actually just drop from the sky. So, thank you for getting the trainer.
I really think that everyone should start with the trainer because it is not
just that it is going to survive all your crashes it is that even something like this, a simple 250 class this hitting new hurts a whole
lot more than this hitting you. I have been hit in the head by these. If this
falls from the sky it will cut someone. It will cause stitches.
Bryan: Don't fly that over a playground or
anything.
Fr.
Robert: Children be careful. Second piece of feedback we have is from a user
by the name of Ean. He write,
“My home router’s DNS service is flaky. It is an action tech 1200,
I can specify which DNS is to advertise from the router. Is there any reason to
include the router in the list of DNS? I’ve moved its 192.168.1.254 entry to
the secondary DNS spot using my ISP DNS at the primary. Steve Gibson’s DNS
bench says that is the wrong way around for performance but I want to make sure
I get reliable internet rather than flaky internet. Any
advice?” Well, Ean. You’re in luck because
we’ve got plenty advice.
Bryan: If there is one thing Padre knows, it’s routers.
Fr.
Robert: And I would
say the way you are doing it right now is absolutely, positively…. don’t do it.
Bryan: It doesn’t sound right. Because you
can look up your ISP’s DNS address and I've done now that one of the ones that has been more reliable for me is Google’s DNS.
Fr.
Robert: Exactly. So
what I would say is dump both of those. You really don’t want to use the DNS
server in your router. Because there really isn’t a DNS
server in your router. It is just a DNS forward. You don’t want to use
the DNS server for your ISP unless you have an exceptional ISP because most ISP
DNS servers are way oversubscribed. They don’t spend enough money on the
infrastructure so what happens is when you type in Twit.tv you get an
extraordinarily long wait. Not because the connection is slow but because it is
taking so long for that DNS server to give you the proper numbers for you to
access that server. What you want to do is you want to use a third-party server
with really good reliability and a good reputation. There are two that I can think
of off the top of my head. The first one is Google, as you mentioned it is
8.8.8. Really easy to remember. The other one is Open
DNS which is 208.67.220.220 or 222. Those numbers are stuck in my head. you will get much better performance. The one caveat is if
you decide to go with a super high-end router like PF Sense,
that can cache DNS entries locally which can be crazy fast but no, ditch
the DNS server for your router. Ditch your IPS’s DNS and you can always drop by
episode 81 of Know How because I did a full segment on fixing DNS.
Bryan: Play around with it because Google
might not work as well in certain areas as others. Here in the North Bay it
works pretty well, but maybe not where you live. So play around with it.
Fr.
Robert: Actually I
know that in that same Google plus grouping people were suggesting you use
Steve Gibson’s DNS tool. Use that on both Google DNS and Open DNS and see which
one works better for you. I’d say you put one in the first spot and one in the
second spot and you can’t go wrong.
Bryan: Cool.
Fr.
Robert: The last
bit of feedback. This is from Jason. He had a questions
about a segment we did the other day about fiber. Remember when we were talking
about fiber taps?
Bryan: And how you would do it by
hand?
Fr.
Robert: You could. But
you need a steady hand. but he wanted to know, “First
is there a standard fiber optic network and second the only reason I would be
interested in fiber optic is for speed. But every card I have seen me is no
faster than Gig E. What speeds can your standard fiber home network reach?” Jason
let me answer that backwards. Don’t use fiber for speed. We don’t use fiber for
speed in networks because for example, 10 gig is about
the fastest you can get over commercially available fiber. There is 40, 80 and
100 gig but those are very specialized. I can get that over copper. I've been
able to get 10 gig over copper for about the last
seven years. It is not about speed. What fiber gives you, is that it gives you
distance. You can go a lot further with fiber and it also gives you the ability
to not have any interference. A copper conductor is essentially an antenna. So
if you run into a very RF rich area it is going to pick up stray symbols and
then you get the transmits and your speakers down.
Fiber is all glass and plastic so they are is no antenna to pick up those stray
signals, so you are not going to get interference unless you get someone that
cuts the fibrin is shining a laser into it.
Bryan: And the only thing that you are
saying with distance but it is as fast as light can travel right?
Fr.
Robert: You are
going to get the same speeds with copper. But what this will give you is that
it will give you distances in kilometers rather than in feet.
Bryan: Very cool.
Fr.
Robert: And now,
back to the first question. Is there a standard for a fiver? There are actual
multiple standards for fiber. The one that you need to know is a difference
between multi-mode and single mode. Next week I will show you, I can actually
show you the difference between multi-mode and single mode fiber. That an easy way
to imagine that is a multi-mode fiber the laser inside this little cable is
bouncing back and forth until it gets to the end. In single mode fiber it goes
in one smooth line it never hits the sides.
Bryan: So is it faster then?
Fr.
Robert: It’s not
that it’s faster it is that you can get the signal to go longer. Much, much further.
Bryan: So would it make sense to use fiber
in a home network where it is not very long distances between?
Fr.
Robert: Not at all.
It is more expensive and you are not going to get any speed. The only time I
would suggest using fiber in a home is if you've got a huge home where
individual runs would be longer than 300 feet or if for some reason you lived
next to a radio station. And the RF is that bad.
Bryan: Or if you had a guest house way out
in the yard or something?
Fr. Robert: I've actually done runs
outside of my house to a neighbor’s house with fiber. For the
simple reason that it doesn’t conduct. I’m in some stormy areas and I
don’t want a lightning strike to conduct through my copper. So I used fiber.
But those are really odd cases. Here is another thing about fiber. When you
start looking at standards what you really want to look at is the one a look at
these things. These are FSP’s. These are modules, that
allow me to interface equipment with different fiber technologies. When I say
different fiber technologies I mean the wavelength of the light that it transmits.
These are 850 nm. You can swap out these modules for different speeds. Like
these are all one gate, this is it 10 gig and it’s
crazy expensive. That you are using the same fiber, you are just using
different types of light through it. To get different speeds.
Bryan: Because it doesn’t matter what the
actual material in the fiber is, it is. just what..
Fr.
Robert: There is
higher quality fiber. For example this is what is called a LC connector and it
looks like a little skinny barrel. These are LC modules. This is what is called
an SC connector. These are a little bit older but they are still very good to
use. The nice thing about these is that I can convert back and forth because
all I need is two pieces of fiber for every connection. One inbound and one
outbound. It makes it super simple when you are setting up a data center if a
connection is not working you can typically just roll it. Just flip it. Then it
works. So, plenty of standards. Use it at home? No.
Bryan: We use it here at twit but we have
a very specific use.
Fr.
Robert: By the way,
people are commenting on my ziplock bag. If you will
notice this is my bad fiber bag. Anytime I've got bad fiber it goes in this
bad.
Bryan: What quantifies it is bad?
Fr.
Robert: Typically
it just means it is dirty. Like this is a dead module that is
why I don’t have it. I would never, ever take a piece of fiber and just
jam it into an SSD because any whale or dirt that you got on the edge of this
connector is now jam.
Bryan: Can you just rub it on your shirt? To get it off? Or lick it or something? Is that how fiber
works?
Fr.
Robert: I will
destroy you.
Bryan: Should I not have been doing that?
Fr.
Robert: Don’t even
get me started. We’ve had a piece of fiber hanging down from the Know Hole,
wrapped around pipes and shoved back in the ceiling. Now when we come back we
are going to go all into Quad Copter frames. Continuing Series for our quad
copter build. You need to choose a frame before you start choosing all the
equipment you are going to put on the frame. We are going to show you how you
go ahead and choose that. But before that, hey Windows 8.1 users: you got some
sticky windows? Let me help you fix it.
Fr.
Robert: If you’ve been using Windows 8.1 with multiple monitors then you
have probably noticed that Microsoft has changed the way it allows the cursor
to move between screens. Before you could just easily glide from one screen to
the next but Microsoft has locked in the cursor so that you need to have a
little bit of speed in order to get through that border. Otherwise it will just
bounce. Believe it or not this is actually a feature that makes sense.
Microsoft wanted you to have an easy way to snap windows inside each display
and that is what that cardboard or does. But if you are used to the way that
Windows 7 treats multiple monitors it can be a bit jarring or downright
annoying. Unfortunately Microsoft really does not want you to mess with the
settings that would change the hard border. Fortunately, we don’t care what
Microsoft wants. To fix your sticky Windows you will need to use the Windows
Registry editor. That is a pretty powerful mojo so I am going to take you
step-by-step, in fact it is so powerful I am going to
remind you again of how powerful it is in about 24 seconds. Hit the Windows
key, then start typing regedit.
You should see an entry for regedit.exe. right-click
the entry and choose run as the administrator from the drop-down menu. The
Registry editor window will now open. We are going to be editing registry keys.
These are the configuration settings for the OS. Let me repeat, this is
powerful mojo. So be very careful in here. The registry controls the way
Windows works and changing the wrong settings can make your OS completely
unresponsive. Follow these instructions step-by-step to avoid borking your installation. First find the key labeled hkey_current_user in the left column of the editor. Click the
triangle next to the key and a new set of folders will drop down. Now select
the triangle next to the control panel, then click the folder named desktop.
You will see multiple objects in the right-hand column. Scroll down to the one
labeled mouse monitor escape speed all one word. If that entry does not exist,
then right-click in an empty area of the column and create a new d word value
with the name of mouse monitor and escape speed. Double-click that entry and a
screen titled edit d word will open. Set the value data to one and leave
everything else the way it is. Click okay. Moving back to the left-hand column
but staying within the hkey_current_user key, click
the triangle next to software. Then Microsoft, then Windows.
Which should also open current version. Then click the
triangle next to immersive shell and now click the folder titled edge UI. In
the right column you will again see entries. You need to find the key labeled
mouse monitor escape speed, all one word. But again if that entry does not
exist, then right-click in an empty area of the column and create a new Q word
value with the name of mouse monitor escape speed and click that entry and a
screen titled edit Q word will open. Set the value data to one and leave
everything else the way it is. Then click okay. We now need to restart Explorer
so that the new settings will take. You could just restart Windows, or you can
hit control out delete to bring up the task manager. Find the task labeled
Windows Explorer and click the research button and the in the task manager. The
UI will refresh and Windows Explorer will restart with the new settings. Now
when you move your mouse between screen borders there should be no hard border,
no sticky Windows. Be free. Run wild. And experience the power of the registry
hack.
Fr.
Robert: I know
there are people in the chat room who were saying I never had this problem with
Windows.
Bryan: I have a dual monitor set up that
you were saying side to side is not affected.
Fr.
Robert: Side to
side is really not a problem. There is no edge border. The problem is if you
stack monitors if you have them up top you are always going to run into that
cardboard or problem. For a while it didn’t bother me that that will idea of
having to give your mouse speed to break through some imaginary barrier like
that.
Bryan: To be fair if you also get kind of
crazy with monitors.
Fr.
Robert: I do.
Bryan: Like might edit machine was just
two monitors until you came along and said you could put more monitors here.
And the next thing I know I have quad monitor setup.
Fr.
Robert: I don’t
know what it is I use them all. I have four monitors for my desk here and they
are always full of stuff.
Bryan: It always looks like something
sinister is happening too. Because you usually have IP Viking on one screen,
the chat room on the other one. Okay Padre you've got a tower of quad copters
here. I heard you like quad copters. I have a feeling we wouldn’t be able to
fly all these at the same time.
Fr.
Robert: Since these
don’t have any electronics on them they won’t fly so well. So what we've got
here is a representation of the quads that we are playing with. We’ve got the
trainers. We’ve got the trainers are what we call a 250 class. And we’ve got
this which is a 250 class, this is the one that we are
going to be building the most. We've got this bad boy which is a 450 class, we
are getting bigger. And then we’ve got this monstrosity that looks like this
would be a…
Bryan: Like a weapon.
Fr.
Robert: This is a
full collapsible frame copter called a 525. I’m going to talk a little bit
about why you would choose different types of quad copter frames. The 250 is
the simplest. This is what I like to start people off with in their builds
because it is a unibody. You’ve got a single frame
that has all the members that you need to be able to mount your motorists and
your controllers in your electronics. This is the flight controller that I’m
using.
Bryan: That looks a lot bigger than the…
Fr.
Robert: Yeah. Because this is a way more powerful controller. I can do all
these crazy settings that make it more stable, make it more agile, make it more hostile. It also has detachable feet so that it
stands up. The nice thing about this is that it is very easy to transport. You
are not really going to have to worry about where you put this thing, it will fit inside of the bad once you take off the
landing feet. And it is super stable. This is the second kind of frame that I
have been playing around with. This is the 450, they
call this one the flame wheel. The idea is that you’ve got these for
independent arms fastened onto this. I like this feature this panel here is
actually the power distribution. So it is a PCP. But that distributes power to
your electronic speed controller from your battery to your motors. The other
cool thing about this is that these are super lightweight members but it also
means since they are individual if you break one you can get a replacement
without having to replace them all. Unless of course you
smash the middle. Putting this together was really easy. Imagine most of
these frames are like sandwiches. You have the arms,
you have a layer at the bottom of the arms and a layer at the top of the arms.
That is what gives you the most stability. Something that I have been doing a
lot with the 450 is sort of figuring out the optimal load balance. As you get
bigger you kind of start moving weight away from the center of the quad or you
can have issues. This is the 525. The 525 is going to run into problems because
it is so big. It is very hard to transport a 525. So this one
was designed to be collapsible. It uses a bunch of these fiberglass
parts with weird landing gear. This is the part that allows you to open up and
close them.
Bryan: You want to tighten that down when
you’re in flight the right?
Fr.
Robert: Oh yeah.
This is probably my least favorite of all of the builds that I’m doing. I flew
this one over the weekend and I just don’t like it.
Bryan: Can you pinpoint why?
Fr.
Robert: I think it
just that it is not as rigid as I wanted to be.
Bryan: It doesn’t give you as much control
as you would like?
Fr.
Robert: Yeah. There
is a bunch of different things that I don’t really like about it. But, I’m not
saying that you’re not going to like it. Another thing is that this was also
really cheap. Of the three frames this was actually the cheapest. So, it is
going to have issues.
Bryan: And the controller for this frame,
is that a controller?
Fr.
Robert: This is
actually a power distribution. So on this one the power distribution is
integrated. On this one the power distribution comes in on the little board. On
this 250 the power distribution is just this harness. It is a cable harness
that has power coming in to the battery and going out to each of the individual
electronic speed controllers. Here is the fun part. No matter how small, or how
big your build is, every quad copter is going to have the same basic parts.
You’ve got a frame. On a frame he will have motors, on
the motors you are going to have props. Those motors will be connected to one
electronic speed controller each. It is just this little device which allows me
to electronically control how much power is going to the motor. So this one has four of them because you need one for each motor.
So you are going to have the four ESC’s, you are also going to have the flight controller, you saw that in the video. It is inside this
case. This will give me control over the handling characteristics in the setup
of my quad copter. But it also controls the for speed controllers which in turn
control the motors. And then you have this. This is the receiver which plugs
into my controller, which controls the electronic speed controllers, which
drive the motor, which get the power from the battery. So every quad is going
to have those basic part. No matter how big or how
small. In fact, if I wanted to I could strip all the pieces off of this and put
it on this 525 frame and it would work. It would be kind of crappy because
these motors are small but it would work.
Bryan: And then this controller that you
have works with this remote that you bought. And then you've just link them
together?
Fr.
Robert: Yeah. In the
more advanced remote control setups you can buy additional receivers and then
you use what is called the binding buttons on the back of this there is a key
that I can press to bind it to that particular control. So, I could buy one
transmitter, by three receivers and then bind to what ever
copter I want to fly that day.
Bryan: How much was that controller again?
Fr.
Robert: $60. It is
not that expensive. There is much more advanced ones. Many people decide to get
a more advanced model because they are going to be doing this a lot. So they
can do multiple FPV or some other weird stuff. But you could just buy several receivers, put them into all your builds because you are not
going to damage your transmitter. Your transmitter is not in the air so it is
going to last. Now people are going to be asking what is the
advantage of getting a big or a small frame. Like we have seen with the
trainer, small frames tend to be a little bit easier to control. And you can
fly these things indoors, they don’t hurt as much if
you get hit.
Bryan: That is an advantage especially if
you are working in a confined space like that, we tend to. The disadvantage you
don’t have as much battery. And it’s not like it could carry anything either.
Fr.
Robert: This one could do and FPV system. You’ll also notice that I’m
grounded right now waiting for my replacement props because I ran this into a
chain-link fence. When you start using these do not fly with damaged props. I’m
going to say that several times. There is a temptation to say oh, it’s not so
bad. But these are spending several thousand times a minute and if you have a
damaged prop and it just breaks off it is going to throw shrapnel. Very bad. Don’t do that. In fact if you are going to be
doing that you really should be wearing safety goggles. I don’t because I am a
bad boy.
Bryan: You are a rebel.
Fr.
Robert: No, because
I am stupid. You are absolutely right. The bigger the quad frame the more it
can carry. And the more means bigger motors. Bigger motors equal bigger props.
Take a look at the prop on the 250 and then take a look at the prop here on the
450 or the 525. The reason for that is if I try to put a 10 inch prop on this
the props will run into each other. So the larger frames can do these 10 inch
props without a problem. They won’t run into any other propeller on the
assembly. The 525, you can actually use 12 inch props. That is getting
ridiculous but you could. The bigger the prop, the bigger the motor you are
going to need and the bigger motor you need the bigger speed controller you
need. And then the bigger battery you need. It is kind of diminishing returns.
You could make a huge quad copter out of everything but then you are going to
have to put more electronics into it, which means you need more battery and
then it makes it heavier and so it decreases performance.
Bryan: Does it make it more squirrelly as
it gets bigger?
Fr.
Robert: I think my
building skill just isn’t at the point where I can make a big quad and make it
fly nicely.
Bryan: The trainer when we have we can fly
in circles around things. If you get good enough at it.
Fr.
Robert: I’m not
saying it is not controllable, it is harder to control
a bigger one. Start with the smaller one. Now there are some things about the
fourth 50 that I like. With this style of quiet, with these size props I do get
a lot of power. I actually get more stability than a trainer. Because think
about it, if I take my thrust and I push it out a little bit further I have a
much more stable platform. Even a 250 is like one column of thrust, they are so
close together.
Bryan: Doesn’t get pushed around a lot in
a breeze?
Fr.
Robert: It can get
pushed around. So what I would say is there is a
couple of things you should think about when you are going to choose the frame
for your quad. Choosing the frame is really going to guide all the decisions
you make about your quiet from hereafter. If you get a smaller frame it means a
smaller motor, which means a smaller prop, which means smaller speed
controllers, etc. So, choose wisely. The first thing is how much area do you
have to fly your quad? If you live in the middle of his city and it is really
hard to find wide-open spaces don’t get a huge squad. You are not going to be
able to fly this thing. Get something like this. Because this I actually could
fly indoors. I would never fly a 450 indoors unless I had a palatial estate.
You will hit everything. We could fly it in here because there’s no expensive
equipment in the studio that we might break. The second thing is how will you
be transporting your quad? If you live in a place with wide-open spaces a 525
with a non-collapsible frame might be perfectly acceptable. If you have to put
it in a car or on a bike smaller frames are better or collapsible frames are
better.
Bryan: And whatever fits your budget to
the bigger you get the more money you are going to have to spend.
Fr.
Robert: Now also
are you going for speed or are you going for maneuverability or longevity? I
would say if you are going to embrace then get a 250. They are smaller, you can
stretch out the wheelbase and you can really get them going. 450 and 525 can
carry a lot more, but they don’t have the agility of a 250.
Bryan: So if I want to race them get a
250. If I want to do some…
Fr.
Robert: Go Pro shots or something, get a 450 or 525. Again as we said,
you can transport the gear back and forth on frames just get different frames.
Bryan: What about build time? How long did
it take you to put that together?
Fr.
Robert: This is
slightly faster because it is unibody. I didn’t have
to assemble anything. This one was slightly longer. And this one took a long
time and I really don’t like it. It was mostly because,
especially on these cheap frames the instructions are so bad that basically I
had to figure it out on my own. It was….
Bryan: You didn’t get this at IKEA did
you?
Fr.
Robert: No, it was
an Amazon thing. Also how much flight time do you want? Because that will
determine how much battery power you need, which will also
affect the size of your frame. How much power do you want delivered to
your motors? Because that will size up your electronic speed controllers and
that will determine where you locate them on the frame. Do you want FPV? Do you
want GPS? Do you want NAV to be able to program? And this is something I think
you need to pay attention to early on. How likely are you to break it? Because
if you are going to snap this thing, if you know you’re going to snap it get an inexpensive frame before you by the super expensive
one. Because these, all of these frames on the table are
under $20. You can buy a frame for as low as $12 all the way up to
multiple thousands of dollars.
Bryan: If you know yourself as well as we
do, just get the cheap one.
Fr.
Robert: You won't
be so sad.
Bryan: Mondog in
the chat room asked if there was any advantage to using a triple blade prop
versus a dual propeller?
Fr.
Robert: We are
going to get to that in two episodes. The next episode we are talking about
motors and speed controllers because you do have to size those. But, pick a
frame because that is going to determine your motor and speed controller. There
are advantages to using three blade props, and disadvantages. I prefer to
blades. I don’t like the three blade once. Some people
really like them but I am not a big fan. It actually does change the
performance. We will talk all about that in an upcoming episode. Now I know
this was a lauded information to take in but we are
actually going to give you all these notes in our show notes. Where can they
find them?
Bryan: twit.tv/kh
And not only are our show notes they are bit past episodes are so you are
definitely going to want to go there so you can follow along the parts of this
project that we are doing. And you can subscribe which would be great too.
Fr.
Robert: Subscribe
and as long as you are going to subscribe why not jump into our Google plus
group. It is a fantastic community. I love pooling questions and projects out
of there because there are just really good ideas. Go to gplus.to/kh…
Bryan: We really should do a hang out
soon.
Fr.
Robert: Let’s do
one Friday. Tomorrow. We are going to do a Know How
hang out tomorrow straight from the Know Hole. We are going to talk about what
you want to see in future episodes of Know How. It is just a great chance to
talk to you.
Bryan: I think we figured out how to do a
hang out. We’ll talk to PixelCore because I think
that is what they do.
Fr.
Robert: Also if you don’t like Google plus you can find us on Twitter. I’m
@PadreSJ.
Bryan: And I’m @cranky_hippo.
That is where you can find our daily exploits and lots of pictures of corgis
from me. What else do you post on there?
Fr.
Robert: Mostly
food. And Giants.
Bryan: And don’t forget about Alex.
Fr.
Robert: Alex is our
TD and he’s @anelf3.
Bryan: You never know what that guy is
going to be up to.
Fr.
Robert: The last couple of days I saw him tweeting from the airport.
Bryan: He did like a three-day trip to New
York and back.
Fr.
Robert: Also don’t
forget that we do this show live every Thursday at 11:00 AM Pacific time. Just
drop into twit.tv and as long as you are watching live where you get to see our
pre-show and all the bloopers jump into our chat room
at IRC.twit.tv and we will talk to you during the show. We will figure whether
or not you are receiving the knowledge pouring into your knowledge hole.
Bryan: Sometime we’ve gone over it in our
heads so many times we skip steps.
Fr.
Robert: Exactly. But
until next time, I’m Father Robert Ballecer.
Bryan: And I’m Byan
Burnett.
Fr.
Robert: And now
that you know how…
Bryan: Go do it!
