I have this esc, and it's great. No thermals and completly adjustable (active current limit, rpm limit, timing, rev-up time, minimum+maximum brake, forward only or reverse, autorun).
It is able to deal with sensored and sensorless motors. I think this is the one to get for racing.

But don't forget about the Motors. the Genius 95 is compatible with Novak and Reedy Motors. But GM also delivers a full range of brushless motors from 3.5 turns to 10.5 turns, sensored and sensorless. All motors are available with special sintered rotors, capable to deal with very high temperatures (180C, I think that's about 350F). The sensored Motors are available with bonded rotors to conform to ifmar rules.

I don't know about the avbailability and service in other countrys, but here in germany there are absolutly no problems about that.

By the way I used the 5.5 turn sensored Motor with bonded rotor last week at the team orion speed weekend and no car with brushed motors was able to follow on the straights. I think there were two guys with the 4.5 turn version in the A main.

180C that isn't too much temp? i remmember you that the hot and magnets aren't good compains, a magnet will lose it's magnetic power easierly if it is hot like a 180C temp. But if the rotors are cheap let's do this

@mmgteam: At TOSW I used a ratio of 8.4. Motortemp was 70C after 5 min run with the bonded rotor. Smaller tracks require ratios of 10 or even higher.

I don't know what to do with a motor to get it to that high temperatures. But I never saw a one of this magnets get weak. GM says they use a special alloy specified up to 180C.
Maximum I reached was slightly above 90C.
