I burned out the elevator servo today in my trex 450XL. after replacing it. went out to fly some more. the fulcrum for the elevator felt really stiff. probably why the servo burned out in the first place. after the heli warmed up inside the house everything was working as it should. Outside temphere is 20*F, so I can only guess the bearings for the elevator fulcrum tightened up or the lube couldn't handle the cold. what do you use to lube the bearings. I have WD-40, a very lite machine oil(sewing), teflon spray. It never crossed my mind that the cold would be a problem. ah, live and learn..
any suggestions?
thanks
