I have just bought an ansmann mad rat. I need help in where to look for parts and what parts are best to get to upgrade it or even make it better.
So far i have bought
The carbon fibre shock towers
The carbon fibre battery holder
The carbon fibre chassy holder
Some blue clips
Some red medium springs
a Big battery 4500

but what else
and how can i make it faster
Also if i turned it into a brushless motor what else would i need to change and what would it cost

thanks and write back
