It turns out I have to use ArduPilot for my project. I'd like to put ArduPilot on my VOXLFlight because of the advantages of a single board flight controller and companion computer.

Is it possible to put on ArduPilot (I know modalAI doesn't support it, but is it possible)? If so, does anyone have any guides? I've tried Mission Planner and QGC and obviously they don't work. I believe the bootloader needs to be modified. Not quite sure how to do this and would appreciate any help anyone can offer. I know I want to do something that is off target for most.

Thanks for your help. Yes, the ESCs use PWM. I may have had something configured wrong, so I'll try again.

I'm a new user and would like to make modalAI VOXL Flight our new autopilot in our fleet, but I have some questions:

1. Looks like you guys don't have a safety button. In that case, how do I use VOXL Flight with DJI ESCs? Or more to the point, my ESCs keep beeping. No way to prepare them to arm. I tried changing CBRK_IO_SAFETY but it did nothing.
2. Is there a place to plug in a speaker, like on other PixHawks?
3. Is it possible to use ArduPilot with VOXL Flight?

Thanks so much.
