New wheels installed, "X2" ready for high speed testing

"X2" with new wheels installed

These new wheels are now the correct diameter and trued for high speed running.

New wheel on the left, old wheel on the right. You can see there is much less sidewall of foam. Hopefully this will reduce the likelihood that the foam will fly off the rim. The new aluminum wheels are much heavier than the plastic ones, but they are much stronger.

Data from a slow speed test using new wheels. High speed for this run about 28 mph.

Weight of "X2" with all electronics installed except for the body, 6 lbs 8 oz.
