Thanks. It weights 4kg ready to go including battery. I used to run it a few years back with the standard tt01 and never had a problem. since i didn't own the donar car I gave it back when my mate moved away. now 3 years or so later I decided to get a new donar car being the tt01e and after 5 minutes or so, problem occurred.
As I am not racing anymore, I am not governed by rules so I want to fit new fast motor and gear it up for acceleration. I see dragnse7en there is a picture of the different holes for the pinions for the motor. I only have the stock motor so 3 positions, but what ration and motor did that come from.
