FMS Retracts

I purchased a FMS P-47 Thunderbolt 5 months ago and I have never flown it because of the sorry retracts included in this kit. One of them jammed and failed on the initial startup and I got a replacement. When I received the replacement and installed it the other one failed and burned up the BEC in the ESC. I have seen some of my friends at the airfield having trouble and complaining about FMS landing gear before. This airplane has cost me for landing gear replacement and ESC replacement and has not gotten off the workbench yet . ABSOLUTELY no more FMS models for me because of the landing gear problems! When I invest $500 in an airplane I don't want to get junk.

FMS Designed Servoless E-Retract for 1700mm Planes

This was a needless expense. If there were descent instructions that explain how to use this new board for the connections then the replacement would have been avoidable. I doubt I'll ever buy another FMS product because of the inferior details about assembly. What a shame

FMS Designed Retract for 1700 mm airplanes

I have fitted these items in a scratch build aircraft as they fit nicely but sad to say I had a failure before first flight.(Thankfully) I stripped the offending retract and discovered the culprit is the microswitch board. I suspect the circuitry associated with reversing motor polarity. The switches themselves appear to function mechanically but who knows? The rest of the retract is very good quality. I don't think I am the first customer to have been let down by this item. Perhaps a quality review would be in order? Thanks JD

Good value for the money

It's kind of silly to spend a lot more on a foam airplane part than and most outlive the plane

Better Buy Spares

I have installed 4 of these in my 1700 FMS Mustang so far. Whatever company in China makes these should Use better chips in the motor driver circuits as one of the 2 chips (either the retract or extend chip) fails consistently. A bit of a pain to replaced since the 12als have to be removed in order to access the wiring. A definite weakness in an otherwise great plane!

FMS Retract

I have several FMS Warbirds- For the most part the standard retracts work fine for me. As long as you are an advanced pilot, and dont have hard landings they work well. The P51 1700mm mustang had a servo failure after just 2 flights on it, with excellent landings. The failure occurred at home-not during flight. This replacement- so far as been fine. Most of my FMS warbirds, are 2 years old, and 95% of the standard retracts still work well. Im hopeful this one will as well. For the price, overall Im happy with them.
