RMMV?

Heh, tx V!

Love the gofastgamernutball replies that I just KNEW I'd garner from yous folks (queues "I love you guys")...

If I read the web correctly, derby wheels have a square surface contact and
are hard. In that case, camber will reduce the contact surface and the
contact point will be very close to pinpoint contact, so scrubbing from
camber will be reduced to a minimum. Worth experimenting with at least.

As for toe, 0 toe will minimize the friction but will make the car change
direction at the smallest pebble especially with high camber. A slight
toe-in may be preferable for stability at the expense of little speed lost.

As for the wheel/hub genius idea, if I understand it well, having the wheel
rotating on a fixed hub will increase the contact surface and decrease the
linear speed. This, IMHO, will increase friction. I would rather go back to
the original design, with a slightly viscous lubricant, to create a liquid
bearing. Once more, experimenting will be required to determine which
viscosity will be enough so the liquid bearing can support the weight of the
car without slowing down the wheels. Since every pebble will kill the liquid
bearing effect, I would go with dry lubricant plus liquid lubricant so you
still have lubrication when the wheel hit the axle when the car goes over a
pebble.

Of course, this is all theory, so Reality Mileage May Vary.
