4s in a TC3

[SpEEdyBL]

Update: I just got done running the 632 with a 17 tooth pinion. Still 180 on the motor after 5 minutes, esc 140, battery 95. Ambient temperature was 90F vs. 75F during the first two runs. Then I increased the timing to 10 degrees, 175 on the motor, and the same esc and battery temps. Now I know for certain this is not a gearing or a timing issue. I'll ask around the tekin forums on the tekin website i guess.

If the Tekin motor doesn't work out, my other choice for a 4s motor and 50 mph speeds or 2s 7700 equivalent would be a novak style motor of 8.5 to 10.5 turns. My novak hv4.5 is the most efficient motor I've tried. During these summer days, it still reaches about 180 degrees, but thats after a full 12 minute run, pulling a buggy that is twice as heavy geared to go 50.
