This quadcopter was dismantled on 1.8.2013 after 21 flights. Using U-shaped motor arms proved to be a mistake due to lack of rigidity. Also the maturity of the ArduPilot software left much to desire. The motors and ESCs ended up getting used in a H-frame quad.

Lessons learned

  1. The collet type prop holders are too often out of balance and vibrations then cause problems
  2. If you plan on flying high then attach some leds for helping seeing the orientation
  3. Watch were the props are when carrying a bigger quadcopter through doorways :-)
