I'm trying to figure out how you would get 75.000 RPM out of the Castle 1412?
It's a 2S motor rated at 6400 KV. So that's 4.2*2*6400=53,700 rpm. Which is screaming but it's a far cry from the rated 75K rpm.
There is LiHV batteries that can be charged to 4.35V, but it's still not enough (55,600). To get to 75K rpm I would need 11.7V or (5.8V/cell @ 2S), which, eh doesn't exist?
So what's the secret?
