I am using a flywoo f745 GOKU which has a built-in 4 in 1 ESC (up to 45 amps each).
I want to make a rover from it by using the built in ESC to the motor. I do not want to use the servo out to a separate motor controller. is this possible?
If it’s a brushless motor you can. Brushed motors are more common with Rovers as brushless usually require some tall gears.
How do I go about doing this in ardupilot? can I set them to go forward or reverse?
Ah, that’s a good question. No, you will have to make that change in BLHelisuite assuming bi-directional is supported. Not to be confused with bi-directional Dshot. I’m not sure BLHeli_S supports that.
