Hello all, My Phantom 1 has the latest firmware. Everything works well except every time I make a yaw input, the Phantom goes off and moves about 8 ft intend of just rotating in-place. I've done Basic, Advanced, and Compass dance calibrations. The compass xyz values are all within +/-400. The mod value is 1400ish. Can anybody here suggest something else to try. Could this be cause b a bad prop or motor? (I don't suspect either bu I honestly don't know what else to investigate) Any help would be appreciated as this behavior makes it imposible to fly in tight spaces.
