Well I had similar thoughts to Sam, but thanks Jay, that helps me
understand why its there. Mine had a cobbled up thing originally
which was scrap anyway , so will work on a lightweight replacement
at some point.

You may be absolutely right Sam that is not
needed, but the reason I put it there is not because of
interference or friction, but because I know from solid
mechanics that a minor flex can cause a long thin walled tube
to buckle instantaneously when exposed to a torsional load if
it is flexed slightly out of straight. I did not do the
catastrophic yield threshold calculation to see how much of a
deflection from straight would be required to fail under
normal torsional working loads, but that was my reasoning, and
it gives me peace of mind. The guard weighs much less than one

Honestly, IMHO a guard is not necessary,
just adding weight and complexity. I have had luggage back
there a lot, and I certainly imagine that it was rubbing on
that torque tube at times. With absolutely no noticeable
difference. Same with the rudder cables.

I like the protection over the control tube, is that
just glass ?
Do you think it would be sufficient to use heavy duty
velcro on the flanges rather than nuts ?
