More Speed!

I don't think your controller is the issue, I think it's fine along with the cell count your running....the 19 series motors will work for you, i think you need to keep your rpm per volt around 2500 or less for the amount of cells your running, this will put you in the 40,000-50,000 rpm range on the motor. the big question is how to gear it for the speed you want without thermaling your system.

I would NEVER run a motor over about 40k rpms. Thats getting out of the efficient range. Stick with somewhere around 35 to 40k....I think there might be a few FET's on your controller went bad...

I agree with you for the Feigao and wanderer motors. They are rated at 50K max. But you should be able to get way with more rpm from the Lehner motors, They are rated for 65K rpm max. I would think you could run it up to 45K easy without loosing much effiency. I could be wrong, but just my thoughts.
