Well made and robust all metal servoless retract unit to suit up to 90 size models. This unit operates through an angle of 90 degrees so is perfect for many types of aircraft, (Please note: the leg retracts away from the motor unit). Incorporated in the retract is an advanced micro controller with intergrated circuit to automatically stop the retract when it reaches the end stops or if something jams, this protects the unit from over current draw and also stops the battery being inadvertently flattened.

I bought 3 of these - 1 worked great and is really quiet and very strong
the other 2 did not work AT ALL - right out of the box !
so a bit of a mystery - currently have a returns ticket under review so we will see if HK can rectify
quite disappointing really - paying a premium for what looked like a quality piece of kit
you would expect they test these things before shipping?Very strong , worth every penny :) . Using in a 17 lbs 2m viperjet with hk 130mm 60-90 size struts , perfect fit . Highly recommend these for your next project , I will be buying more .
