REFLECTOR: Aileron Rigging

[Brian Michalk]

I think Brett has it right.

Measure the throw of the cable ends where they attach to the aileron 
bellcrank, and make sure left and right extend the same distance.  If 
they do, then it's a misalignment of the bellcrank.
Your mounting of the bellcrank to the torque tube could be off, or the 
bracket that locates the bellcrank in position could be off.
