Pixhawk 4 + Arduboat Airboat

I’m trying to build an Airboat with differential thrust
I have:
Pixhawk 4 with the power module
R12DS Radioink receiver
AT10 Radiolink transmitter
2 80A ECS
2 brushless motors 620KV

I have installed AurduRover/boat

I have connected the ESCs to M1 and M2 in the power module,
however, the M2 (motor 2) is not working

anyone out there that could help me out


Hi, luigi. The servo output is M1 and M3 whether you’re in Separate Steering and Throttle or Skid Steering. Please check this article from ardupilot.org
