Geesh guys... I'm 50 years old, and have all my fingers and toes... I've done things that would make most any of you run for momma, and you get all worried about a wheelchair? OF COURSE i would have to change the caster wheels to a steeringwheel setup, make the rear tires run in unison, etc. and maybe cantilever the wheels out at the bottom to help with cornering, but lets face it, just like the muscle cars I grew up with, they didn't turn too good, but man, did they do a fun strait line... that's what I want - a button like nitrous to a third battery.... I'll try it and let ya all know... I wish I could afford the rocket powered chair, but he cheated - its a rocket with a wheelchair frame welded on.... I want a real chair!! I have three, and getting a new one, so I'm ready to build...
