Hello, i have apm2.8 and connected to mission planner when i arm only one motor spin, i dont have transmitter, but also when i kind of test calibrationMOT the other motors spin as well but they donot stop till i cut the energy source.
Yes, even when i connect pins of the motor that work to other outputs is work fine i think there is a problem with esc however all motor work in compass/ motor calibration only
