The instruction manual that came with my Futaba has a section that explains how to tighten the gimbal springs
When I got the controller, I tried to tighten the springs but realized that option wasn't available. So, I like using my real controller instead since it doesn't feel cheap and is exactly what I will be flying with. I just don't like having to charge my transmitter after a day of simulator flying.
And funny thing is that one of the reasons I didn't get FS One was because I thought the controller felt cheap. I guess I kicked myself in the face on that one.
