REFLECTOR: Ailerons

[Alex Balic]

Are the joints placed right up against the aileron with just enough room to
rivet/bolt them in or a bit further inboard?

I can't send you pictures since the universal joints are inside the wing.  

 

All you have to do is purchase the proper size universal joints that will
fit the inside diameter of the aileron connecting piece and the torque tube.


 

See  http://www.aircraftspruce.com/catalog/appages/ujoints.php

 

You will have to shorten the torque tube to make up for the additinal length
that the universal joint adds.  remember that the inside diameter of the
aileron connecting piece and the and the torque tube have to be the same.

Jim,

 

Can you send or post pictures of your universal joints?  Even better, do you
have a recommended part number?
