Hello all,I had a problem where one of my motors would just twitch when throttle was applied. It was debugged here: http://www.diydrones.com/forum/topics/one-of-the-motors-does-notYou should double check the soldering on your motor leads where they are attached to the longer leads about 1" away from the motor casing.I had two of these joints fail on two different motors during bench tests. Not a weakness you want to take up into the air.Have fun,Wes

  • Hi!

    Confirming. I have had 2 cases like described...in air. Don't know if gods at my side were from ancient Greek or from somewhere else :) but I managed to save my copter somehow (deffective motor started again after taking throttle to 0 and then to max). It didn't happen on 3-d time!

    Cause was a motor wire soldering covered with heat -shrinking tube. It was mechanically ok (couldn't tear it apart) but cutting off the tube revealed a poor soldering, probably due to too much heat applied during shrinking the tube.

    As they say - electronics is a science of contacts....
