REFLECTOR: Dual Throttle Quadrant Part 4

[lawrence epstein]

The system you have in the last photo
looks like a good solution, except I am concerned about having the
controls in a different order left-Right on the 2 quadrants.



I like the idea of completely separate systems back to the engine compartment. This eliminates a single point failure (of both controls) mode.

What does the factory system look like (I think they offer that option?)

Sorry for so many emails. I am lousy at descriptions and I do much
better with pictures.



The next direction is I took three pieces of steel tubing from
Aircraft Spruce and put one inside the other. Then I braised on steel
tabs and used a bolt on each side braised to a flat plate for a bearing
to pivot on. For my linkages, I took flat steel rods which I cut and
drilled
6 exact duplicates which I attached with clevis pins to the throttle
quadrants and tabs on the steel tubes. Then I took the reversing
throttle quadrant on the co-pilot's side and modified it so it would be
non reversing, which is needed with this new idea I am trying.



I attached a picture of what I hope will be the solution for dual
quadrants. I was wondering if anyone has been down the current road I
am headed and has any pointers.



This is turning into a HUGE time sink. Almost makes me
wish my wife were not a pilot too, which would have negated the need
for
dual throttles.
