What little hair I have is puled out!! I'm working my way through setting up an apm 2.6 for the fist time and am stumped. I'm using Afro 30's and have calibrated the radio and the ESC's but when I arm the copter the motors spin slowly as they should but only accelerate very slowly and no where near full speed when I apply full throttle. The are very responsive in the calibration procedure so they can spin up to full throttle but they won't under flight conditions. Any help would be really appreciated.
