Here I have 5 different Micro FPV quads – the Mobula 7, Gnarly Primo 2.5 inch,
Armattan Tadpole 2.5 inch, Pygmy Rattler 3 inch and the Diamondback Rattler 3-4 inch hybrid.
A couple of them have the same Caddx Baby Ratel camera and 4 of the 5 fly with TBS Crossfire. But
there's only one thing all 5 have in common and that's an All-In-one Flight Controller also known
as a Whoop flight control board. This is where the flight controller and the ECSs are combined,
all in one board. Not so long ago, these were only used for whoop-type quads with tiny motors
Just within this past year we've seen these types of all-in-one
flight controllers get beefier ESCs with higher voltage ratings like this BetaFPV
Toothpick F4 V3 AIO Whoop Flight Controller with a 20 Amp 4-in-1 ESC that I have on all
3 of these quads and it works great! The point I'm trying to make is, we're in the middle of
an All-In-one evolution and, in my opinion, this trend is only going to increase with the use of
all in one flight controllers for FPV drones of ALL sizes. These all in one flight controllers
aren't just for Whoops anymore! Today, I'm going to introduce you to a new one I've just come
across and compare it with the BetaFPV Toothpick F4 V3 AIO Flight Controller I've been using.
This is the Flywoo GOKU GN745 F7 All In One flight Controller.
It comes with a 470 microfarad 25 volt capacitor and some grommets
and even comes with an xt60 connector and leads. It weighs in at 7.81 grams.
32.94, 32.94. The mounting holes are your standard 25 and a half
by 25 and a half. It's got two different BECs for 5 and 9 volts. It's got a 3.3 volt pad over here.
It's got an 8 megabyte flash black box chip and a barometer. It takes 2 to 6s power input
and has a 40 amp continuous current rating. It's got an eight layer pcb which, among other things,
means it's going to be more durable than others. This is the documentation for it and it's got
the complete wiring diagram for you showing both digital and analog video transmitters,
various receivers, your buzzer and leds, a gps module, and even a bluetooth module.
It also shows you how to configure your ports tab for the various UARTs. Now, if you're concerned
at all about how to make any of these connections to the pads on this all-in-one flight controller,
no need to be intimidated. Let me show you how quick and easy it is to solder a wire to one of
these small pads. I'm going to use this 3.3 volt pad here for a little demo. These are some of the
soldering tools I use. I've got a complete list of all my build gear on the "Build Supplies and
Tips" page on my TMac FPV site I'll link to in the video description below. First, I always set my
soldering iron to 475. That's what I found works best for me soldering these micro FPV drone parts.
I use a narrow pointed tip rather than a flat one. Next, we tin our solder tip
and wipe it down with a wet sponge.
This makes it shiny. Then we tin our bare wire with a little solder.
Now we just gently paint the pad with a very small amount of solder . . .
like that.
Now we move the bare wire into position so it's touching the solder
on the pad and apply heat with the tip of the soldering iron so the solder flows.
Remove the solder iron and the heat and it solidifies. There we go. All
done! Let's see what Betaflight firmware it comes with. We connect to our computer,
go to the CLI tab, and type "dump all."
Then we scroll back to the top. I haven't done any configuration of this flight controller at
all yet. We scroll back to the top and we see that it's got Betaflight 4.2.0 installed with
our target for our firmware as Flywhoo F745. While we're here I might as well copy this dump all file
with the firmware it originally came with and paste it to a Word document. Then save it to
my computer in case I need to reload it again in the future in the "highly unlikely event" I screw
up the firmware somehow! This is always a good thing to do. So we go here to hashtag "Version"
and copy all of this. Copy . . . Word document . . . paste and save this somewhere to your computer
for safe keeping. This firmware that it comes with (4.2.0) should work just fine the way it is and
there's no need to flash it with any other newer version unless you know for a fact, by reading the
version release notes, there's features on a newer version of Betaflight you need or you want to
have. I mentioned earlier I was going to compare the Flywoo GN745 all-in-one flight controller to
the BetaFPV F4 V3 all-in-one flight controller. I thought while I was at it, I might as well compare
all four of the flight controllers I recommend on my website for your micro FPV drone build.
I've also included another all-in-one flight controller which, although I haven't tried yet,
appears to be comparable in most aspects to the Flywoo GN745 F7. The iflight all-in-one Beast
F7. The features we'll be comparing are over here on the left. The three all-in-one flight
controllers are in the first three columns whereas the 20 by 20 flight controllers and esc's are in
the last two columns. So, when it comes down to size and weight, remember for the 20 by 20 stacks
you need to add the weights of both the flight controllers and the ESCs. So,
with the all-in-one flight controllers you're not only saving weight but you're also saving space
with one board instead of two - which means if you have a frame that allows you to lower the
top plate by using shorter standoffs such as any of my Rattler frames, you get the added benefit of
saving weight with the shorter standoffs as well! With regards to power input, I run 4s on all of
my micros with at least two and a half inch props. So all of these meet that need. All have MPU-6000
gyros which is good and none of these have pin connectors (which I also think is good). When it
comes to the number of UARTs (which gives you the ability to connect various peripheral devices),
I want at least three and the BetaFPV all in one gives me that. However, the Flywoo GOKU all-in-one
which has seven is amazing and actually beats out the two 20 by 20 stacks in that regard. They all
have good documentation although the only place I could find the iFlight F7 (documentation) online
is at Pyrodrone. The other three features that are important to me are external buzzer support
(since I like to install self-powered buzzers like the Lucky Box or ViFly buzzers. For me,
they have to have black box capability since that's an outstanding tuning tool
and we're now also able to use the black box gyro file with just about any camera to stabilize our
flight videos similar to GoPro footage. Eight megabytes of flash memory will get you about
one to two average duration flights logging capability before you need to erase the files
to record again, which is really no big deal at all. I want the ESC's, whether they're integrated
with the all-in-one flight controller or as a separate board, to have at least a
20 amp continuous rating. If you're aware of any other all-in-one flight controller
with black box capability, a similar number of UARTs, and at least a 20 amp ESC rating,
let us all know in the comments below. Of course, cost can always be a factor. Looking at all of
these options, if they're in stock I'll be using one of these three all-in-one flight controllers
for all of my builds and preferably the Flywoo GOKU GN 45 F7 all-in-one flight controller.
It's got everything I need and more and at a very reasonable price point. Now you've got an idea of
what this Flywoo F7 all-in-one flight controller can do and I've got a decision make on what build
to put it in. If you've got an idea let me know in the comments section below. For more fun stuff,
make sure to check these out next. Thanks for your time. I'll see you next video. Clear skies friend!
