Thanks guys! I never drove the Wraith with the stock trans and motor, but I'd guess on a 2s pack it's as fast as a stock truck, probably 15-20mph. Fixed the low RPM issue, the sensor wire wasn't quite all the way in on the ESC. It crawls great now, very little difference between the pro4 and the 35T brushed motor I had in low range.
Just came in from my first full pack, slipper is still slipping occasionaly, and it's 1/8 from all the way tight, guess I'll crank it on down or look into another slipper setup. I got around 40min with a 4000mah pack, mostly short blasts up hills second gear under high load, and could lay my finger on the motor endlessly (didn't grab the temp gun since it never got warm enough to worry about), even at the end of the pack at LVC (3.2v per cell for me). Racing tomorrow, but got a new spot scoped out for next weekend to go shoot some dirt hills on 3s. I couldn't be happier with this thing, honestly I'm ecstatic at how the motor / ESC combo works. Too much fun!
