RE: ntc3 starts to spin under high accel...
welcome to RCU. When a car becomes unstable, it is usually attributed to poor chassis setup. Pick up a copy of the XXXMain tuning guide, it will help tremendously. For right now, take a look and see what way it spins out. most likely, it will spin the same direction every time. which ever way it spins out, tighten the rear shock on the opposite side. Usually spinning out under acceleration means that one of the rear tires is receiving more traction than the other. By tightening the shock on the wheel that is getting more traction, u are transfferring weight from that side to the other.
