REFLECTOR: Aileron cables for side sticks

[jerry at jlbent.com]

All,

I don't see the interconnection anywhere in any of these three designs.
One thing to consider is according to how you do the inter connection, the
apparent length goes from the length of one cable to the combined length of
both cables and can actually make the drag unacceptable.  This would happen
if you chose option three with a connecting cable between the airleron
torque tubes.  Any way you connect two long cables you will still have
significant drag.  Another consideration is the flutter characteristics due
to the addition of elasticity with two long cables.

Just my thoughts.

I've chatted with a number of builders in the past few weeks in the
Velocity Builders' Virtual Hangar. I've discovered that a number of us are
installing the side-stick option and want to eliminate the torque tube in
the keel.


Scott Swing has indicated a willingness to think through an alternative
connection method for us, probably involving control cables that run all
the way from the sticks to the wing root. A few options are presented in
the attached PDF. These are my sketches and thoughts, not Scott's, and I'd
love the community's input. I'm leaning toward #3, since it has the fewest
parts and takes the least design / re-engineering, but might be talked into
one of the other options if it is safer, easier, or philosophically more
elegant. :-)


Let me know what you think. Also, please contact me (directly is OK) if you
too are interested in a more direct connection for your side-sticks so I
can tell the factory how many of us there are.
