At first glance these retracts seem good quality and made from metal alloy.
Unfortunately there is a weakness in the design of a little aluminium peg inside that the motor winds in and out. The peg is very fragile and one of mine broke after just a few uses.
Fortunately for me, I have a lathe and managed to make a new one from steel which is going to be much stronger. Just a big hassle though as I'll probably have to replace the others too at some point.
Good points..... Good strong retracts that look great and work smoothly
Bad Points........Liable to brake little aluminium peg on motor driver due to design
quite heavy for the size.This is a real heavy duty retract. It would easily support a 10-12 lb. model. Bought this as an aftermarket replacement for a 90mm EDF jet. The nose retract needs the flange for mounting on the upper side and not the lower side.
