I'm a little slow and was wondering what the difference between proper rudder pedals and racing rudder pedals were, but a synapse finally fired off I guess you are talking about clutch, brake, and accelerator? Yeah, I guess it's possible. I use digital buttons for steering my SRV in turret mode, but it's not ideal - and neither is the twist stick.
I wish I could use rudder pedals, but I think I'm just to big and fat right now and I'd probably break them, but I'm losing weight quickly. I can't even think of playing BOS/M/K w/o pedals. But when I lose the weight, I'm going to look for a nice set of heavy duty, wide stance pedals (because I'm still big guy), like my old aluminum frame Thrustmaster pedals I had back in the 90's. Then I can lose the twist stick and get a proper joystick. And hopefully by then ED will have really recaptured my interest.
