Before You go Chucking in the Brushless, I will be Build a Speed TT-01 Edition for Just that .. Straight line Speed.

I will See How the TT-01 Handles a 14x2T and let you know how it goes as far as reliability is concerened but for Drift, the Brushless is Overkill

Nice to See a Beefy Battery in there.. that should allow you to get the Motor Maximum power and Duration..

Sports Tuned Will push that Bad boy allong nicely and with some ABS or PVC Tyres, It will Drift Real nice..

Cant wait to see the Finished Product.. Looking great..

Do you Still have the Plastic Prop shaft installed???
Upgrade to a Alloy Prop Shaft ASAP it will flex and will end up snapping in time causing a Whole World of Pain..
