All wheel designs to be tested in the next high speed run.
On the left is the 1/8 scale on road based wheel and on the right is a much larger OFNA style on road wheel. The OFNA based wheel has a much larger inside diameter and outside diameter. The idea with the OFNA based wheel is to minimize the sidewall size of the wheel while keeping the outside diameter close to 3.25". The tire needs to be trued down to correct size. You can also see that a hub isn't used to attach the wheel to the motor shaft. Instead a mount using setscrews is used to tighten the wheel on the motor shaft.
"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.
