Associated TC3 w/ Mamba 7700 Noob Help Please
I have browsed the forum for the last couple months, and found plenty of good info. So I finally bought a TC3 FT kit. I purchased a Mamba 7700, and built a 8.4V seven cell GP3800 battery pack. I use the car on smooth parking lots mostly to race in a straight line. I have a couple issues with the car. If I go up a grade the car will take full throttle, but coming down the grade with less of a load on the motor, it acts like there is a loose connection. It spits and sputters badly. The gearing is the stock 72T spur with a 21T pinion. Should I gear the car lower? As it sits now the car on HPI 31mm and 26mm Vintage D compound tire the car spins out of control often under acceleration. I have not used the software to make any changes to the esc, I had a hobby shop setup the esc. I also noticed today after doing a burnout to heat the tires the car was only front wheel drive. It was way more controllable in this configuration but was much slower. Once I got home about a hour later, I noticed it was back to being 4wd. What would cause this?
Thanks for any help Scott
