Hambone Posted May 9, 2018 Report Share Posted May 9, 2018 There is "stiction" in the flaperons. It seems to be caused by one or more of the flaperon hinges. It sticks, creaks, then pops loose when moving the stick left and right. It is making pattern work very difficult! It is especially noticeable when the autopilot is working to keep the wings level in turbulence. Anyone else have this issue? Link to comment Share on other sites More sharing options...
FlyingMonkey Posted May 9, 2018 Report Share Posted May 9, 2018 There is sn aileron centering spring, is that what you are feeling? Or is it a new sensation? Link to comment Share on other sites More sharing options...
Hambone Posted May 9, 2018 Author Report Share Posted May 9, 2018 I don't think it's the centering spring. There is distinct stiction as the stick is moved left and right. Eventually the stick force overcomes the stiction, and the flaperons move. Squirting a bit of lubricant on the hinges partially helps until it wears off.

Hambone Posted May 9, 2018 Author Report Share Posted May 9, 2018 I'm afraid it is also putting an excessive load on the aileron autopilot servo... and on my arm, too! Link to comment Share on other sites More sharing options...
FlyingMonkey Posted May 9, 2018 Report Share Posted May 9, 2018 You probably need a thicker lubricant on the hinges, like some grease on a Q-Tip. Youmay have to get your mechanic to disassemble and service all the pivot points and lube the rod end bearings. Link to comment Share on other sites More sharing options...
Roger Lee Posted May 9, 2018 Report Share Posted May 9, 2018 It is up by his bracket and may need the flap bracket bearing broken lose and centered better. It is binding some. Someone may have also got the Loctite 480 in the bearing and it's rubbing and not turning smoothly. Link to comment Share on other sites More sharing options...
Hambone Posted May 9, 2018 Author Report Share Posted May 9, 2018 It appears to be the outboard left wing flaperon hinge. Link to comment Share on other sites More sharing options...
