Tighting up controls

That is an excellent idea Mike. Looks like version three of the control stick may be needed.

Hi John,

I've only this minute discovered the commencement of this forum. I have had a look at your problem and suggest the following...

I would convert to linear potentiometers, dual carbon track type. I use 75mm long with 60mm travel. I see your roll motion axis probably only tilts left and right about 40 degrees. If you had a small swing arm linked to your axle, it could be directly linked to the linear pot converting every movement of the stick to instant response with minimal components in the drive train.

For pitch you could use the same method. Mount a linear pot on your roll rod and pick up a push/pull point somewhere just up from your joystick's pitch pivot point. This would eliminate all backlash and deadband. Linear pots are much easier to set up than rotary pots in general. This is how I will set up the pot drives in my A320 TQs.

If you would like some sketches additionally to help explain all of this, let me know and I will draw some! I often see gear drives and other complicated methods of interface in peoples sims which are usually avoidable and unneccessary.

Regards, Gwyn

Thanks Gwyn. You and Mike have given me much food for thought. I am 1/3 of the way through a two week bsiness trip. I have time to think, plan, and develop ideas.

I'll make a sketch for you, it might be useful to others too!

Hi John,

Here's a sketch of what I was thinking about!

Looking again at your set up you could pic up a linear pot drive from your centring piston damper.

Thanks for the drawing. I like its simplicity. Since I am going to be modifying my control setup, I want something that won't require me to disassemble the entire sim.

The "KISS" principle is always high on my list!
