I am posting this in the general electric section because not may people respond in the Team Acadamy area. Ijust got the car assembled and the motor will spin up, but the car would hardly move. I opened up both diffs and tighten both up. This has helped considerably, but I just put in my new brushless system, and the diffs just seem to slip a lot. I have to start out very slow and be very gentle with this car. Is this normal for a 4 wheel drive buggy? My last car (a back yard basher) was able to accellerate harder than this car.I can't tighten the diffs anymore than Ihave. Are there any other suggestions? Someone please help me out.
