21.5 conversion is easy. Pick up a Yokomo BL-SP3 (cheap), 21.5 motor and three lipos. Boom you're done.

I wouldn't say it's not competitive, but the R1 Wurks Ultra Premium is built under ROAR rules. Which means it's not an outlaw motor, and in Japan outlaw motors are allowed and the way to go. When I mean outlaw I mean outlaw. Maybe R1 Wurks might come out with something for the Japanese market. Who knows?
