Hi,
I'm developing a fairly large experimental racing drone and have bought a set of 4 VESC's to use on this monster.
Yes it may seem excessive, however I've come to this after testing quite a few large multirotor ESC's - none up them are up to the toque loads and voltage spikes created by a system of this size. I'm not an electronics or firmware expert, more of a frame designer so not really sure how to get the flight controller to communicate to the VESC.
We use a serial based receiver (SBUS) and the ESC/Motor protocol out of the flight controller can be PWM, Oneshot125, or Multishot. Can also do what's known as Dshot which is a newer digital protocol system. Any of them are fine, basically they're faster than PWM in various levels.
The output signal from the flight controller is from 1000µs to 2000µs.
Can anyone please give me some advice on how to make this work?
It would be phenomenal of the BLDC tool could have options for multirotor applications like this. I see huge potential for a solid ESC like this in the multirotor market.
Thanks in advance!!
Kind regards,
Sam
I think you'd be best off to start with using pwm input on the VESC. Sure, other methods are faster and better, but this should at least get you up and running. Optimize later.
Has you tested VESC on this quadcopter? How it works?
DId anyone figure out how to use a vesc with betaflight?
If so please private message me with info if posable.

Is VESC supports multi rotor UAV application ?
Currently I have tested on UAV application by having input from Futaba's receiver. You will need to set it to no reverse in input mapping as no reverse would give your motor weird rotation behavior. I did a prototype using schematic of VESC 6.5 plus which give a very good response on the motor with propellors.(note: it is a T-motor U8 with 28 inch prop)
