I was just offering some input to someone on another forum using an Arduino to add force-feedbake to a yoke and it made me think about all of you with the full size sims. Something you may want to consider for your control return springs- you could fairly easily add a proportional feedback to the resistance that could change by speed and also add the feedback when turbulence is encountered etc.

 

The code would be pretty easy with the Arduino as the control device- just the actual mechanics would need to be developed. Perhaps a large stepper motor which shortens or lengthens the distance of the return spring by a swingarm.

 

Thought I would pitch this out there while several SIMs are still at a stage you can work on this area easier. If you can build the mechanics- the code would be pretty easy.

 

I found this that falls along the same line of thinking. This might actually be easier for you guys than most people recreating it for two separate yokes. Perhaps just one heavy duty setup (Driver MOSFET/Output ICs are quite cheap now for 20 amps and more) The feedback on current trim of the aircraft alone would be amazing.

It's funny you bring this up as I was just researching this the other day. BFF males a lot of great products such as their shaker system that I am very interested in trying. They also offer a force feedback/ control loading product that is super easy to integrate. I am only interested in the elevator motion. I have not used Ron's duel linked setup in his sim yet but I am sure now that he has them linked the aileron feels good and stiff. I have a bit of time in our Gulfstream sims and the amount of muscle needed to manipulate the controls is pretty heavy.

Interestingly enough, the card to run the stepper motor from BFF is £119 uk where as the Arduino mega or even the smaller nano boards are £13 UK about $10 that and some priceless code from Eric and it makes a good solution.
