I guess they need to start checking 101 of them because I encountered that same problem, my set screw actually broke after trying to reverse it back out when the strut came lose, and if you have checked for this problem before than it must happen to just me and this other reviewer. Simply put just go buy the eflight and be done with headaches. (Posted on 4/24/12)

Paul, please contact our service dept as we have tested over 100 of the screws without seeing this. Thanks for your help. Matt

i installed a set on a parkzone p-47....installation was straight forward and electrical components worked well......the weak link is the set screw that holds the wire strut in place.......the brass insert that the set screw goes into became loose from the retract body.....as the set screw is tightened, the insert backs out.....i guess i will try a e-flight set...
