REFLECTOR: Aileron Belhorn Configuration

[Brian Michalk via Reflector]

You may have already examined the design, and I'm just mentioning this 
for informational purposes.

If you look at the stick roll arrangement, it's asymmetrical.  The stick 
is mounted to the right of the torque tube.  Rolling left causes the 
stick to rise out of the keel, and the opposite to the right.  The net 
result is that you get more travel in one direction than the other.

The second nit I have is that a bolt carries the torque from the stick 
to the TT.  Yes, you can fashion a bearing surface, and I have done 
this, but the result is that there is some play generated by this 
arrangement because you can't tighten this bolt tight enough to remove 
the play.  It must allow the parts to slide against each other and 
transmit torque to the tube.

One of these days I plan to move the TT to the center of the keel, and 
make a new stick that the TT pierces.  The torque will be transmitted in 
shear through a bolt, meaning that it's working on both sides of the TT.
