I do hope so Serum. I was comparing the specs of the HV range of motors:
6.5 = 3100kv = 44640 rpm = 14.4v = 500 watts
4400 = 4400kv (original one I have) = 63360 rpm = 14.4v = 375 watts
4.5 = 4800kv = 69120 rpm = 14.4v = 800 watts

Those figures are way too high on the HV4400 & HV4.5, no wonder they get so hot and suck the life out of my poor cheapo batteries. The 6.5 has potential though- 45,000 rpms isnt too bad on 14.4v, and it has much more power output in terms of torque due to the newer sintered rotor. There is a video or 2 on youtube of someone running their Emaxx on 16.8v with the 6.5, and it is rather quick. I know sensorless is way better and cheaper by-and-large, but if I could get a 6.5 motor for fairly cheap somewhere, I reckon it would make and ideal upgrade having more torque, lower kv and cooler temps as a result. Food for thought, seeing as I am a 'casual' user rather than hardcore racer/basher.
