Hello Paul-

Got the gaskets made & installed on the prototype slide throttle.
Result is (what I judge to be) a pleasant amount of friction to move the
Teflon slide -- about where I would adjust a friction ring on the
throttle handle itself.  I don't know how much more friction will be
introduced by the vernier throttle cable assembly -- it hasn't arrived
yet.  Should the linkage break, I believe the throttle slide will tend
to remain where it was last set -- even under vibration I don't see it
moving forward or aft on it's own.

Someone here was commenting on not allowing the slide to fully close --
this is prevented by the slide itself; even at the full aft position
(against the spacer plate) the slide it partially open (about 5% lets say).

So far, so good...

I did the stop on purpose. You can adjust it by adding a screw
in from one end. To close it down more trim the Teflon.

I think it will free up a little after it wears in.
We had no problems with a long (about six foot) throttle cable on the dyno.
The other option is buy thin sheet Teflon from McMaster that is etched
on one side for gluing and epoxy it to the front and back covers.
Then you have Teflon on Teflon which should be REAL slippery.
Haven't tried it yet so you would be on the cutting (bleeding) edge.
The throttle cable control I specified is also Teflon lined. But it
will have some friction.

If you put a 2:1 lever in the cockpit to get more travel that
will also reduce the force required by half.
