REFLECTOR: Aileron slop

[Pat Shea]

Rene,

I think you are suggesting one tension cable
connecting both aileron bell cranks together. If so,
based on the previous discussions of asymmetrical
throw of the ailerons, you may want to consider using
a spring in-line w/ the cable to allow for this.

FWIW, Pat
