Hi, I have the Thrustmaster RGT FFB also, and ya the Force Feedback can be really stiff, best thing to do is to turn down the feedback in the game, dampening to 0 then play with the force.
But I was wondering if you knoticed a way to remove the insert to the screw for the clamp. Only because I think I stripped that because my tabel is curved and its hard to get it to go on. So if you know if you can or not, just pm me please.
