Just a note: We are running the Can Am motors. If you haven't visited that thread you should do so. At the USIC I tested about 9 of the WGT-R motors and found them to be very close in Kv and amp draw. On the track I didn't see one pass or even much speed difference on the sraights. Now several local tracks have adapted those motor rules. It ticks some people off because they spent $$$ on motors and gained an advantage that way. The motors are around $65 new and are set to a spec then sealed at the manufacturer.
