Very interesting.  Thanks for sharing Dave.

I was making noise over your house this afternoon.

Next time, I'll pick you up and we can fly down to Hanscom to pick up a few toroidal props to test. :)

One other thing for the reflexor control. Do not put a detent at your neutral position. Neutral at 900 lbs will not be neutral at 1250.

 Take care--------------  Chris

I use the lawnmower type ratchet throttle cable from Aircraft Spruce. It's compact and works just fine. I have it mounted in my center armrest, just aft of the stick. I normally only touch it two or three times during an entire flight.

Re: Reflexor

I like that idea Vern,
I think that will work way better than a coil spring

Thanks for the advise guys

Re: Reflexor

Frankenbird Vern
 

 The centering detent makes sense and having a "stick" backup to the elevator is also a very viable point. Redundancy is good. 

  So..on this line, my plan is now to incorporate both but for the concerns about holding a position the easiest "factory method" design 
I can think of is a larger flat steel washer, then Belleville washer with the correct smaller AN flat washer under the bolt head. The stack 
keeps the assembly in compression.  Install on the reflexor pivot bolt.
 
Use a drilled head bolt and safety wire the pivot bolt to prevent any chance of it backing off, thus loosing compression pressure. The idea 
is to add friction to the system but keeping it smooth acting, so a bit of flight testing is in order to obtain that "best feel".  Belleville washers 
are a very good design for maintaining tension. The lifetime wear limit on this item with a bit of candle wax as a lube would exceed other items 
on the aircraft.   

  Very little weight or cost (Grainger has a big selection of these types of washers). Only the bolt and smaller flat washer needs
be AN hardware. Your safety wire hard point could be another drilled AN bolt floxed in the bulkhead or whatever design you decide. If a 
hardpoint "tab" I would make it in steel. .025" is more than sufficient.     


Best regards

 Vern

Bruce raises a good point here. In an emergency, for example if one or more of the links to the elevator breaks or becomes jammed, the reflexor is a back-up pitch control, you would like it to be usable in that regard.

Looks delicious!  Will the vernier let you move the reflexor quick enough?  Will pushing the button be an extra function that will slow the movement down to much?

Re: Reflexor

Kevin Boddicker
 

I have a vernier cable on my plane as does Fisher. Where I got the idea.
Haven’t flown with anything else, so your concern my not be relevant, as I don’t know any other 
control movement. Seems perfectly natural in the arm rest below the throttle.
Also pushing the button and moving to desired location is quick, and second nature.
The fine adjustments are made by turning the knob very slightly. Literally an eighth of a turn will
have a profound effect on pitch.

My 2 cents. FWIW

  Mike---------------  My reflexor is set with the control on the
forward side of the bulkhead, same design as yours.

Because the reflexor donut is snug and the aileron torque tube is well
lubricated there is no creep, or any other movement in my system.

My actuator is a lawn mower throttle with the normal lawn mower throttle
friction. No detent at all and it stays where you set it.

  I am using the heavier wall solid  bowen cable. Not as big as yours
and if you use a lighter cable it may flex instead of moving the reflexor.

  With my hand on the throttle I can easily tweak the reflexor for
desired position.

  You are making good progress and i always look forward to your
