REFLECTOR: aileron binding

[Andrew Ellzey]

I reamed out my dust covers and it helped mine. I also changed the routing to give a larger bending arc inside the cabin before going through the gear bulkheads, this probably helped the most. My aircraft is the XLRG with the -5 cut down keel option. I called the factory and asked if the XLRG-5 aileron control cables were supposed to be shorter than the standard XLRG and they said no. My thoughts are that they should be at least 2 inches shorter to allow the bending arc inside the cabin to be routed correctly. I'm not flying yet, but they did tell me that the control forces would be lighter in the air than on the ground. I hope to find out in the next few months.

>With the Aileron torque tube travelling through an arc – a spherical bearing will help with binding.  In my case, I’m going ‘old school’ (aka Long EZ/Cozy) – and using a universal joint at the connection between the torque tube and the aileron, in conjunction with the spherical bearing at the wing root.  Parts are available off the shelf from Cozy Girls, and Infinity Aerospace.  Let me know if you’d like part #’s, etc.
