I too am having serious problems with a pair of E Flite 6-120 electric retracts, including what seem to me to be several design errors, the most important being the grossly inefficient (6%?) lead screw system. This makes marginal operation, excessive current and the risk of flat batteries far worse than otherwise.

Rather than repeat my detailed analysis and fault symptoms here, I refer you to http://www.modelflying.co.uk/forums/...91&p=2#1218304
