Motor power is different(diagonal)

Hello, I made one aircraft this time, and I found out that the average output of motors 1 and 2 is about 100 different from those of 3 and 4. What does it mean to diverge diagonally? I guess it’s not because of the weight, but because of the PID setting. Is that right?

Not, to PIDs are not to blame. CG, propeller differences and twisted motor arms are to blame for that. And you should fix it.

Thanks for the solution! :wink:
