Last weekend I made up a new set of lines for my Vampire (36 profile carrier plane). After I was done I noticed that there was a hitch in the action, when exercising the up and down movement at one point there was a bit of a snag. When I looked at the plane it was obvious what was happening. The bellcrank is under the wing and fits is a slot in the fuselage. The bellcrank had developed some slop and was tilting up and down more that it had before thus causing it to tip enough that it hit the side of the opening in the fuse. The base of the bellcrank was still solidly mounted to the plane but the slop was in the slider/bearing area.
This bellcrank/airplane has about 4 seasons worth of flights, not really that many. I would hope that it would last longer than that.
My question(s) are, has anyone else had a problem with the bellcrank becoming sloppy like this? Is there a way to relliably fix it? I am concerned that if it gets too loose it could come apart in flight, not a good thing. I am also afraid that if I try to stake the bearing or slide it will not be reliable and smooth.
Any help?
