how do you set up the vehicle+ramp to go straight+consistent.?
I have lines on my ramp, and I've lined up my wheels onto the lines. I'm using rollerblade wheels, and its hard to match something that wide accurately+consistently.
Its a little better now that I'm using spacers between the side of ramp and the vehicle, but I am still getting significant left-right innaccuracy..like, .1degrees off,(2cm sway if I try to line it up exactly..)
I believe that one team at my regionals got 11mm off and had some type of pbc tube for the wheels to track on(but I didnt see it in person). The pipes were cut in half so it was like a trough.
Sounds like it would cause friction if wheel was too wide, and if wheel too thin, the track wouldn't do much...but 11mm!!
I have these bearings: 1/4" ID; 1/2" OD

It says its good for high rpm; is this the quality/type for gv?
