Here is a look at the way to change the high resistance transistors in your BGC to low resistancs high current MOSFETs.
This mod boosts the current going to the motor and turns a standard BCG or MS into a rocket.
Once modded it will pop wheelies after rolling in reverse, and screams accross carpet like its on floorboards.
It now loves high revving motors, the higher the better, and can still pull wheelies with a 3.8 motor and the highest gear set.
Power is improved massively and because its not carrying the weight of an extra cell it takes corners at full speed without flipping or spinning out, its like a different beast altogether.
A 1.2V FET modded car with a 3.8 and high gears will leave any dual cell for dead, both off the line and especially around turns.
The beauty of this mod is that YOU CAN CHARGE THIS HIGH PERFORMANCE BEAST ON AN ORDINARY CONTROLLER CHARGER !!
Here's how it all looks
2 of the MOSFETS are mounted underneith the circuit board
The other 2 are on the top in the same places as 2 of the removed transistors, then both pairs are wired together to form a new H-bridge that drives the motor. Thats them at the bottom near the V+ and F terminals.
Once its finished there is no external differences and you can charge on a standard charger
