I read where you were looking for the same info Mac. I guess no body really knows for sure. I may just end up buying an after market M11 wheel. It may barely fit. But I would have to slightly mod the DX3R steering mech to fit it on. Both the M11 and DX3R have a 7mm square hub on the radio. However the DX3R unit has small raised lines on the hub to prevent the M11 wheel from sliding down on it. Just a small dremel job to flatten the lines, and there ya go!
