Yeah, that's true... I like more around 40 - 45K....
but you have to love the sound a brushless motor running over 100000rpms...

Sorry for the hijack... but.. I once aciddently ran a cheap himaxx 5500 rpm/volt motor @ 22.2V.... she moved my 15Lb e-maxx pretty good... and after a few minutes... I heard cracks... and the magnets looks like small stones...

but my MGM is still kickin'.. ..
