LOL, what I meant to say was:

High quality motors don't need a lot of timing to perform well. :lol:

you know you could prove to the world how good CC is and make us some roar aproved motors and change up the game untill everyone else catches up again.

then we wouldnt have to race with red and bash with green:party:

quick thred jack while i am here



can the MM handle 144300rpm or are the shudders comeing from the poor motor:whistle:

sadly the motor is running pretty cool for being that far over voltage

The issue is the ROAR rules -- they require a three slot, two pole motor with a tiny rotor and a huge number of turns. This would make a good low RPM, low torque motor, but we use them as high RPM high torque motors. High RPM motors should have a low number of turns to minimize inductance effects, iron losses, etc.



How many poles is the motor? If its a two pole motor, then yes -- that RPM is no problem. If it's four poles or higher, that's pushing the ESC a bit.

Really the only issue with high RPM is that the timing will retard slightly at high RPM because the microprocessor starts to fall behind on the rotor position estimation. Adding a bit of advance will help.

Thanx!
