Well to all that have been following this thread ,, I've started having trouble with my retracts too .   I first started with them powering up off the flight battery, that was ok for a little while then they started stalling on me and using a l;ot of juice ... Now I have them hooked up to a deducated power supply with a 6v life battery .   Got wiring diagram from this thread . But one side would fail to cycle  only about about once in 6 trys .. When it was mounted in the plane , it was very sporadic, take it out and it worked  every time . It was detrimined that there was a slight shift in the retract  to cause it not to cycle .  I put a 5/32 washer under the 2 screws closest to the wheel . This let it shift , but not shut off .  now they work ... if they don't I'll post up ..
