Hi everyone! I am having some issues with my tricopter that I built recently, when I'm flying the tri one of the motors will stall for a second then come back on. It does this randomly when it's flying and has not resulted in a crash yet. The set up is David's Tricopter Design with Afro 30amp esc and DT700 motors and a kk2.1 flight board with stock firmware. Any help would be great and happy flying!
