RE: Bellcrank choice or similar for plane
Macommy
It's my opinion that the carbon rod would flex the 1/2 inch you need without endangering the rod. The rod is of a fairly small diameter - .070 I think, so it will bend some without breaking. If you are lucky enough to live close to a LHS that carries the CST display you will find CF rods there and you can get a feel for the flexover that 8 inch distance you mention. I'll have to measure my 2m pattern plane and see how much I have sticking out of the fuselage and maybe disconnect one of the clevises and see how a half inch deviation from it's natural position feels. I'll try to remember to do that this weekend and let you know.
Thanks,
Tom
