Here's my TT-01D drift spec. Out of the box it drifts pretty good BUT it is excellent on low traction surfaces such as tile. Just upgraded to 15T motor so I can get more power on rough surfaces. I prefer drifting electric because it isn't as costly as nitro. If you want something fast then get a good ESC and a motor lower then 15 turns. Here's a [link=http://www.youtube.com/watch?v=KQSKA30oWPk]video of when my TT-01D was drifting STOCK.[/link]
Running 23T Tamiya Sport Tuned motor and Tamiya 23T ESC provided in the kit.

Now running 15T Orion Method R motor and Novak XRS 15T ESC with brake and reverse. (Wiring a bit messy because I ran out of zip ties..)
