I've read about
Rakesh Dhawan's new company: Falco Emotors. The original Tidalforce's 1000 watt motor put out 72nm (newton meters) & had a 7 phase motor. Other motors that put out similar power tend to be 3 phase motors (phoenix etc) resulting in more cogging.
The Falco website states that the Falco uses a 5 phase motor & that their 1000 watt motor puts out an astounding 80nm. Their system is also an "open" system (you can use 3rd party batteries). I'd get one, but my 750X is still running just fine (albeit on SLA batteries).
