Choice Of Motor For Brushless Jato

But the 4600 on 14.8 volts give 68080 rpm:035:
I've read on a forum that brushless notor can't spin more than 40000 rpm !!!!!

The Feigao 10L turn 2458 rpm/volt, they give about 36378rpm on 14.8 volts, maybee this setup will last litle more time than the CC 4600:026:

And i've an other question about the Jato drivetrain, how it'll hold all this brushless power ???
