i need a new esc for my tt-01, i got a 19t motor in it right now and i have a 12t laying around, i would like to be able to try to use the 12t motor but if not o well. wut kind of esc should i buy? my funds r limited to around 50-100$ right now. thanks

What size is the 12T? Is it a 550 or 540 size? I think the Novak Rooster can down down through 12T on a 540, and it can handle Lipo if you decide to go that route in the future. I think it is about $75 on Tower Hobbies. There are a whole bunch of ESCs that cost about $50 that can handle down to a 15 turn motor. Novak XRS, MC330 [I think that is the name], and the XL-5 to name a few.

idk wut size it is, its not a name brand motor, it just says on it 12t-3.

Hmmm, well if you are willing to spend the $, the Rooster looks like a match.

EDIT: Oops, my fault. I thought it was $75. It is $85 on Tower. Still a good ESC.

Tazer 15T work very well, i have one and it's very well build and it's dirt cheap...like 29bucks from lhs.
