Now Retract 004 upgrade to FMSRE047, it is better than the Retract 004.

FMS designed rotating retract set for the FMS 1400mm F4U 

This new set of retracts (includes right and left) for the 1400mm Corsair is a HUGE improvement over the old version of the retract. This set has complete metal trunnions, metal jack screw, metal stops on either side of the retract, and a thick and rugged plastic housing. These will not collapse. The micro switch is under the jack screw and trunnion as opposed to the old design where a hard landing could break the micro switch. This design includes channels to stop the trunnion from moving so it physically cannot collapse during a hard landing. We find these retracts to be a HUGE improvement over the old retracts. These retracts also operate at 1/2 the speed of the prior version so they open and close at a much more scale speed (about 6 seconds to open, 6 seconds to close). This is a perfect rotating retract for planes up to 8 pounds and OEM on FMS 1400mm Corsair sold after 3/2014
