Lipo questions

I don't know - I've never had a TC3! I had a pro4 previously and hte TC4 seems to be a little more forgiving to drive and easier to drive out of the box (I could never get used to the one way front diff). The parts quality isn't quite Pro4 - but then again, it's not a factory team. I don't need to run a 4200 in my track - it's only 70 feet by 40 feet. There really is no use going ove r30 mph cuz the track is so small. In fact, when I'm using 4s, it's too fast for that small track. Going 0-40 in 1 second gives incredible torque steer - almost no front traction also. In addition, after about 10 minutes, the diff outdrives start to melt - even if they're REALLY tight to start with. So, now I've got metal outdrives.

Mike, you should really use a smaller rotor motor for TC's. Get a 400 series motor. The "spool up" is way quicker. When comparing the basic 3600 vs. a c4012s, (3500), the Hacker is quicker and more responsive. Same top speed. With 1/10 tc, the limiting factor is traction. There is no way you can put down 700 watts of power to the ground on a 3 lb TC. Doubling up on the batt is definitely a good thing - with the 4200 geared approx 10:1, you'll be pulling about 50 amp peaks. Geared just a tad taller, you'll pull 60 amp peaks easily. Good thing you're doubling up on the 11.1 volts.
