(All stock Arducopter 3.1 settings.) It wants to roll to the right. I can only even it out with full left input. The accelerometer is calibrated, and the artificial horizon in Mission Planner displays correctly. All radio channels display correctly in Mission Planner. Motor order and direction was verified via the "motors" command. Prop direction has been triple-checked (at least). Also, I find the throttle to be ridiculously hot. Also, the pitch (elevator) is reversed, even though it looked like it was showing up correctly in Mission Planner. Parts List A lot of this was just scrounged together from parts I already had, so I don't claim that this is an ideal build, although it does work fine. Motors: Turnigy NTM 28-26A 1200kv ESCs: Hobby King 30A (flashed with SimonK) Props: Hobby King 8045 SF (have also used 9047) Battery: 4S 2200-3000 mAH (various Turnigy and nano-tech) Flight controller: Pixhawk and GPS from 3DRobotics Receiver: FrSky X8R (connected via SBUS) Frame: FliteTest AnyCopter hub, Knuckle H-Quad parts, and landing gear made from clothes hangers :)
