compared to HW,Sp and many others at 3300kv .please read about increasing the kv rating and how its done its about the config of the wind .delta or star.

No!
ROAR don't mess around with essential things like connecting a motor Wye(star) or Delta.
I think iv'e heard someware that a Delta connection makes the squareroot of Pi or 1.77 times more power than Wye or something along those lines...
8.8.2.3.3 ROAR Spec 10.5 motor: Only three slot “Y” wound stators are permitted. No delta wound or slot less stators are allowed. Only circular (round) pure copper magnet wire permitted. The three slotted stator must be wound with 10.5 turns of 2 strands of a maximum diameter of 20AWG or 0.813mm and two strands of a maximum diameter of 22AWG or 0.643mm per slot. The resistance for each slot of the stator shall be tested and a minimum resistance figure will be determined upon submittal.
It is very easy to get a high Kv by adding more endbell timing but torque suffers.
That is also why it could be a really good idea to have more timing avalible in software!
