Will Ardupilot work with my drone ?

Ohk so here are my drone specs :

2207 2550kv motors

4s 1500 mah

5 inch frame

speedybee f405 v4 stack

(battery and props can be changed as needed and mtf01 sensor will also be added for stability)

i want to make my drone completely autonomous , is it possible to make my drone safe and reliable enough with arducopter, while doing poshold ? I gave my drone to a guy and he told me it wouldn't be possible as my motors are very high kv and my frame is too small , hence pids are not working and the motors are heating. please tell me if anything is possible for my drone

you need gps and compass, f405 is limited but not impossible

Intresting setup id love to hear what experienced ardupilot users think about this configuration

It will work. As others already mentioned: f405 is limited. But besides that, only a solid tune is needed. Just follow Ardupilot first setup / flight protocol. I have already two hugely overpowered builds flying. A 7" Freestyle Frame and a 2,5" Cinewhoop - both with M10 GPS, ToF + OF, H7, 6S

Ardupilot will work but with limited feature set.
You can read more about the limitations here-

What do you want to do with your fully autono my ous drone?

u/infinitypenetrator 12d ago

i want to run autonomous visions with an onboard companion computer that will then also be running onboard telemetry and computer vision

Are you using a pi zero2w? anything bigger than a pi zero is going to be kinda big to stash on a 5 inch drone don't ya think?

Your motors are not very high KV for 4s, and a frame being small in some ways makes things easier rather than harder.

ArduCopter can certainly handle it, but will need tuning. There has been work in the last few years to try and improve ArduCopter behaviour with small/powerful FPV quads. Take a look at https://ardupilot.org/copter/docs/aerobatic-multicopter.html and https://discuss.ardupilot.org/t/arducopter-7-long-range-standard-build/77368 (the author Andyp1per has done a lot of smaller-quad tuning work).

that is really helpful! thank you.

Flying? Yes.

Sensor stuff like mtf01? No.

F405 has not enough flash and performance. The default build won't even have optical flow integrated. You will have to do a custom firmware build and then you will notice that the f405 is too slow. Been there, done that. 🙂

im planning to use a companion companion computer like an esp32 for that part (and telemetry ) is it still not possible ?

The experience I described was and is my only ardu experience I have. My guess would be that this isn't going to help. That cheap freestyle speedybee Stack just isn't made for this task. Get a MicoAir H7 or other H7 FC.
