So.. I decided to race my TT-01 in VTA. Man, what a great car! I'm not AS fast as the other guys, but getting pretty close. The main thing was the gearing. I made a custom, round motor plate so I could rotate and adjust the gear mesh (like the old losi street weapons). And, I found out if I drilled out the FF03 gear adapter for the shaft... it fit normal gears!!! Wowza! This car is truly an amazing tank of a car!
