[B4 Sloth]

Initial Acceleration - Use this to limit the initial power that is sent to the motor when starting from a complete stop.

Using the LOW option, the vehicle will launch very slowly and provide the longest run times. When using the HIGH choice, you will have wheel-spinning acceleration at the cost of run time. This is also very tough on the batteries as the amperage draw can be very high. If your vehicle cuts out, hesitates or loses radio control, you should consider setting this at a lower value.


v Low
Using this option will provide longer run times and is easiest on the batteries. Good choice for beginners.

v Medium
Medium requires more from your batteries, and is good for low traction surfaces.

v High
This option will provide full acceleration and requires stout batteries to supply the load required in this setting.


CAUTION: You may experience what seems like the motor cutting off, a hesitation or possible brief radio loss using this setting.

Taken out of the manual. I had exactly the same problem. Once set up on the pc it was fine. You dont lose top end...must be a fail safe. Try with no load on the road, all would be fine..add grass and stop!!!
