control column pitch centering using gas struts

Great work ! Could you tell me where you got the actuators from ?

Cheers

Wow Claus,

This looks fantastic. What force are the gas springs? Those actuators look interesting indeed. Source?

Michael,
Very nice installation. What size are your gas springs and where did you get them? I think something like that would wwork on my sim and I can put it beneath the floor board (out of the way).

Sorry for the late reply.
My gas springs are 200 newtonmeter. You can find this gas spring in a kitchen store. It's used for vertical hinged doors. Or here https://shop.angst-pfister.com/ishop...E844843AB13436

Then, the cockpit has been reassembled, and 2 nights has been used with small short flights from one airport to another, to test and to make small adjustments on the flight controls.
It become really good, and the trip to fitness center can now be skipped when you have to pull and push with approx. 6 kg on the steering gear, almost like the real airplane. So you quickly learn to use the trim button.
The autopilot dons't move the flight controls yet, this function must be integrated later on. But who can also get the idea to fly on autopilot .......

Have not even made control column yet, but have had these thoughts about the design.
If you connect the 2 rails together and mount them on a different track system, this system towed by a motor controlled by the autopilot.

this is basically the same design I am going with for my dual controls but with springs for centering. I have an electric linear actuator that will drive the shaft inside a linear bearing. The linear bearing will mount inside the 2" square tube that the actuator is currently sitting on. I plan to use a L shaped control arm so I can adjust the throw of the actuator.

This is is the linear bearing that will be installed in the square tube. A shaft will pass through it and springs at each end will attach to a lever on the main control axle. If anyone sees an issue with this plan I'd be interested in hearing your thoughts.

Be aware that there may be major forces in the different anchor points.
Your design looks good.

Thanks Claus, the weak link will probably be the actuator itself. It's rated for 135lbs but I'm not sure what the holding power will be?
