Summary:
This thing rocks!
With 32pitch gears i hit a peak efficiency of 88% (!!!!) but i didn't have a low enough gear ratio and ran out of brake on the dyno.
...
Overall this motor performed excellently.
88% through gears into the dyno -- And with gear losses, the real efficiency is even higher...
All in all, excellent news on the Neu/Castle motor front.

whoooaaa!?!?!?! ran out of brake on the dyno? awesome! what voltage was this at? these new motors make some serious power in a 1/10 scale size package! I ran a few high speed passes with the 4600 today on 2s with the watt meter and was impressed to say the least. highest amp draw was 100 amps and peak watts was just shy of 760 watts!!! under this load it recorded the voltage droped to about 7.5 volts. dont know how incredibly accurate this turnigy meter is but it works well enough to get a real good idea of whats happening. great power output! next time i go to the track i will try it again in a race situation and then again with 3s to see what she does.
