| I'm close but yet to test -What's a T - Curve ???
Right know the numbers posted above were obtained with ATV's set at 100% and a full obtainable mechnical total collective pitch of -10 = +10.
The design of the SE front end, limits pretty much any deviation of geometry changes in the linkage except for length or shortening the related rods since all servo ball centers and arm pivot points are fixed geometry.
The collective servo begins buried in the frame, using a wheel and two ball links and parrell push pull rods leading in a vertical up posistion to a T type tiller, attaching to the bottom leg of the inverted T.
The ball link center distances of the wheel and the bottom legs of the inverted T are factory matched and fixed parraell geometry.
The top leg of the inverted T, leads off with a link to the aileron cyclic servo which rests in a seperate rocker frame pivot and is allowed to tilt. These center distances for the rocker, the pivot of the T and the cyclic spread are fixed.
This adjustable collective link actually attaches to the center servo wheel hold down screw. The left / right cyclic servo wheel then has rods leading back to the 90 arms for left and right and to lift the swash.
Hence you rotate the collective servo, it swings the top of the inverted T via push pull, top of the T leg rocks the cyclic servo for collective lift, and it also rotates for cyclic.
The only thing I can really tamper with further is to shorten the four links that lift the swash, hench lowering the swash, then go back thru the train again.
