Great video Lee, and a great tutorial on using Arduplane on lower cost FCs!
Thanks so much for being so responsive to the community and your patrons!
Thank you uncle
This is incredibly helpful to me. Thanks Lee. Once you explained it, it seemed an incredibly easy concept which I should've quickly sorted in my tricopter build a couple years ago 🙂
ah you did this too. I doing this atm to an OMNIBUS F4 nano V6 , just for giggles in an Conscendo S , Might have to recompile INAV to get an extra servo channel to split the ailerons.
You are such a gifted teacher, thank you! I have that EXACT fc and was wondering if I could use it in a rover. I think this puts me on the right track. Thanks!
Thank you my friend… I’ve been bingeing your vid’s and just finished my first rc plane and I’ve been inching to try inav or ardupilot
Thank you, this was a great education.
I've been doing this for a few years now. I started because of size and price point. I have found a few boards thar actually have extra motor pads. For small boards I like Mamba and Skystars. Never tried vtol and using a 4n1 esc make sense. Thanks for posting this.
This is awesome! I've been dying to get one of these guys, or one of the H7 minis and do this!
I really wanna build a whoop scale quadplane!
Very instructive 👍
Such a good video !
this was exactly what I needed. I got one of those ultra cheap omnibus f4 boards without 3 pins for motor output, I think it is the OmnibusF4 V3S plus, only 26 bucks from ali express. I haven't got any of those header pins so I'm going to try to solder up a servo wire connector system.
I have a few AIO boards for quads that have a blown ESC. I figured I could use one of those for this.
Fantastic!
Doing the same with omnibus f4 v2/v3. Have 1 board working the other not sure if its a reciver issue Or uart. Rang your nuts off had the fix for the omnibus. I like the servo extension.😊
Awesome, I was wondering if this was actually possible and turns out you can 🎉, I must admit my soldering isn’t good enough right now to feel confident to spend on a expensive fc and not feel like I’m gonna wreck it with every solder so could be a way to go a bit cheaper or a used one and give it a go , much appreciated sir
Nice video, I have converted a number of kakute FC for use with ardupilot planes. The best thing to do for power is to use a Holybro power distribution board with current sensor. They are usually not too expensive.
Great tip! Thanks for posting! Happy flying
@@Painless360 Also just finished a build where I used a ‘holybro 4 in 1 esc mini’, it has current sensor and only one working esc. But all works great for the plane.
nice!!
Brilliant, Lee! Thanks a bunch for the tip! 😃
Would the wiring work for iNav as well?
Anyway, stay safe there with your family! 🖖😊
I've not tried with INAV... Happy flying
Matek also makes a servo PDB that will do the job of the pin header power rail thing.
What's it called?
I love this video as i have now a way to use my speedybee 405 v3 FC as the esc broke down, one question though i dont seem to get any voltage readings anymore, is that due to the missing fc telemetry?
Probably. If it depends on the telemetry from the attached 4in1..
I am looking for something similar, an AIO with at least 2 integrated ESC, and 3-4 servos for a Heli and Rotorflight.
Is it possible to flash speedybee f405 to flash ardupilot ?
So I think I saw a post/answers on using the VTX control in Betaflight to turn on/off your HDZERO and the author was having issues with the VTX booting when powered using a switch/settings.
A few people said HDZERO does not recommend using that method.
Maybe I misunderstood the question/answer…I’ve never used that setting.
There is a note on the HOLYBRO website for this FC to not use it with DJI too. I wonder if the output can't supply the current that they need... I prefer to use a physical power JST connection in my builds for all HD systems... Happy flying
Thanks for this helpful technique. My situation is on the opposite. Since I am a newbie in this field, I 'mistakenly' bought a relatively cheap Speedybee F405 Wing APP without knowing that it is for a fixed wing plane. For the time being I have no plan to fly a plane (but a drone). If you have videos in the past which may help me converting this FC for quad copter, please let me know, I would be very grateful.
Not really, best of luck!
The board used in the video is a good bit more expensive than say a Matek F405-wmn. I looked at the FC list on Ardupilot and it seems most boards are still over $50. Is there a low cost board that runs Ardupilot and can be converted for use in fixed wings?
The process shown will work with any as covered in the video. See the 4 things you need to check.
Omnibus f4 would be the cheapest route to Arduplane.

Maybe me being thick, how do you power the wing esc? the esc has the + and - wire from it, where would that go on the fc? or could i use the full stack and just connect the 3 motor wires to motor 1 on the esc? or do i run 2 wires from battery to fc and also attach the esc wires to the same battery cable?
16:35 run battery direct to ESC with battery voltage sent to FC to power it. Best of luck
@Painless360 perfect thank you! Looking forward to the new heewing video when you get it and release it 😏
Can't we connect the red wire to the power line of the pin header you made for servo, and use it to power the board as well ? Or the BEC 5V output would be too low for it to work as it needs 2-8S ?
Try it out and let me know.. Best of luck
not a good idea at all, servo power lines are very noisy and that can generate a lot of problem if not correctly filtered
Thanks, how about current reading on this kind of FC?
If you want that then you'll need a companion PCB to read the current and send it via the current pin. To be honest, if you want those kinds of features then get yourself a Matek or similar... best of luck
Thanks mate. Is the STL file for this plastic case on your Thingiverse please?
Done! www.thingiverse.com/thing:5943893
Ta very much sir!
I am a little confused about the ground wire going to the FC, my esc has a 5v bec+ & - which is plugged into the custom pin doohickey. My FC is powered direct from lipo, so would I still need the "GND pin on FC" wire from the diagram? It would link my vbat ground to a 5v bec ground, im inexperienced in electrical so I dont know if thats normal.
I'm not sure I understand the question. The ESC will need battery power, and will only need the signal connected. Signal ground is good to have too... Best of luck
@@Painless360 Thank you for the quick response! The lipo directly powers my esc and the fc. Then the 5v bec being used for servos is from the esc. So would I still need the ground wire soldered out the back of the custom pin thing going to fc? I am signing up on patreon now, you definitely deserve it
Message me on there from now on, I've sent you all of the links on there to Patreon exclusive benefits too.. Thanks again!
hi
Do you think I can add a 10.4 V Lithium battery to this and a powerful out runner brushless motor and 2 HS-82MG or similar servos to this along with 10 Amp brushless ESC? Do you think this particular controller with the modification you suggested would be able to handle it?
And an RC/telemetry system as well.
It sounds like you are new to this. I wouldn't try and adapt a flight controller like this for an early build. I'd get one of the flight controllers designed for a wing/plane (Matek F411-WTE, Matek F405-WMN, Matek F405-Wingv2 or SpeedyBee F405-Wing).
@@Painless360 thank you so much. Do you think these off the shelf controllers would be able to support the Servos and the 10 Amp brushless motor I mentioned above?
Yes, please check out the series building that I do, aimed at beginners.
Great video as always. Unfortunately, this Kakute board isn't exactly cheap. When I saw title of video, I hoped that you would use truly cheap board in range 30-40$ (but with this prices today, I'm not shure that that is even possible).
It is. I'm guessing you're not a regular viewer. See the series using an Omnibus F4 flight controller linked... Happy flying
@@Painless360 Im trying to be regular, but I entered this "sport" few months ago and for every answer that I find, I have 10 more questions :) Thank you for your fast response.
Also check out the new Speedybee F405 Wing FC. $US40!
@@sarahdaviscc tnx, I already ordered one
All my boards are current & in use.
But I do have a few f3 omnibus I could possibly use for a wing. But I just threw it on betaflight & it won't let me flash it with the last hex in 4.0 or 3.5.7.
I knos they no longer supported but what gives.
No target in online so I do a local hex then click flash firmware but it doesn't start.
Do I need an earlier config version say 10.5 or something. Anyone know.
That's something I'd raise in the Github for Betaflight. I'm sure there's a way but they need to make it easier to find... Best of luck
I think in the most recent betaflight they have"cloud" builds where before you flash you select fewer features so the firmware will fit on an f3.
is its possible to use a speedybee F4 V4 drone FC like this
With the Speedybee F405 Wing being so inexpensive, I'd buy one of them now rather than fight to modify a Quad FC... Best of luck
@@Painless360 but is it possible to convert the quad fc ? Rather than buying a wing fc
Maybe, I've not tried it with one of those... best of luck
Not sure how it works in Ardu software, but one thing that is very important to note if you want use a quad board with INAV for a plane is that you cannot remap the signal wires. This is important if your board onlt has 4 motor ourputs, since in INAV the first two signal outputs is preassigned for motor output. This means for a flying wing with just two servos you will use S3 and S4 for each servo and probably have S2 unused. 3+ Servos is not as easy. There is something called "Servos mode" that I have not tried which I believe will make it so all outputs PWM, this means you will have to forego Dshot 600 for example.
Check out the series linked in the description to see how it works in Ardupilot... Happy flying
Nice Video . I was wondering also what i can do with my small FC aio i have with one burnt mofset . so i have 3 motors available . maybe a small 2s wing plane or a tricopter style drone.
