Ok Here is the Deal...

You spend money on Turning a Toy RC into an Even Faster Toy RC , in the end it is still a Toy..

Drift the Drift King till it Breaks then buy a Hobby spec RC and Swap the Wheels and Shell over..

It will never performa as Good a TT-01 even if you manage to Put a 5.5 Brushless into it

Why is it called a Toy RC??

1. Unmodifiable... Good luck pushing more then 7.2 Volt without frying the Board..
2.. It has Very little if any spares available for it.., so when its Bevel gears go it all over rover/
