Is it Possible to have Two Alternating Pistons in Blender Physics? I am trying to do a two-slider animation using Blender Rigid Body physics.
I want each slider to go on opposite direction at any time.
I tried using Force fields but to no avail. Almost every video on youtube about Blender Physics is about Demolition.
This model is for the ailevon (aileron+elevator) mechanism for a jet aircraft I am designing.

Currently, with the current settings, the ailevon (the Green cube on your left), is only going up, that is, in one direction. I want it to swing up AND down.
I first tried using only one slider. But it didn't work. So, I thought using two sliders would. That too is not working.
Am I missing anything.
Any idea is welcomed!
Robin Betts comment was probably the closest I was looking for.
However, in the meantime I have switched to  a more simple mechanism proposed by the students of Delf TU in Holland.
Here is how I rendered it.


They key in making this happen is by setting the piston to Animated and building keyframes on it. The rest moves by itself through Physics.
Thanks to all!
