Ok, 2 runs so far.

Vehicle is a pede vxl 2wd, with the stock 4.6" tall talons. Castle creations sidewinder sc system, no fan on motor or esc. 50% puunch control, 50% reverse, all other options stock.

3s lipo, 5000mah 25c. 14/58 gearing. 10min run:
lipo - 100f
motor - 120f
esc - 125f

2s lipo, 6400mah 30c 20/56 gearing. Not quite 10 mins before it thermaled, repeatedly
lipo - 100f
motor - 120f
esc - 148f

Thoughts: well it appears that even running 3s lipo thru the stock bec is better than trying to pull the same watts out of a 2s setup. I plan to make another run with the internal bec bypassed and a ccbec to power the servo. See if that helps the esc temps on 3s. Keep in mind I have thermalled the esc running 3s on a longer run. Maybe a fan over the esc would help. I would prefer not to have a fan.

The motor does not seem to mind the load. Even with lower voltage and higher gearing it is about the same temps. Actual performance was not as good on 2s, I have a feeling the esc may have been the limiting factor and not letting the motor pull as much as it may have wanted???

The sidewinder sc is a fantastic value, and I think that it would work great on 3s in a vehicle like a slash 2wd or rustler. Maybe my pede is overgeared slighly, and I know my bashing style is tough on electronics. I think the sidewinder esc will be replaced with a trusy MM in this truck, and put in my M03 tamiya that strickly runs 2s and a much smaller motor. I will do more testing 1st as I want to see what it is capable of.
