The TC3 will go about 25MPH with a 27T 24° stock motor. I got mine second hand, and it is a gem. Indoor racing season is just starting in my part of the country, so I just have to replace the slicks with foams, and I'm ready for some indoor racing action! Touring car racing is addictive!
You don't really need exotic stuff to keep up with the fast guys, I use a $25 DuraTrash....er...Duratrax ESC, and Trinity Zip Metal Hydride 2500 stick packs. Sure the guys with matched/Zapped/slammed/buzzed packs and $150 ESC's are faster, but not by much. I am consistently "mid-pack", over some folks with a lot more money in their cars. Just stick with stock class, so the motor is more or less the limiting factor as far as speed goes.
