Dude I would definitely encourage you to look up www.fantommotors.com as they are a real racing engine and wow what power. I mean for the price of what that motor is going to cost I am almost sure you could have a fantom for something close to that price. Great motors full of power.
the fantom is a good one for a little more money , more rpm. the epic is also very fast for only 150 bucks at towerhobbies.com. i use the fantom 15 and its a rocket. i also heard good things abuot the epic. but if you get either one , you need a REALLY high flow pipe. even my 15 pipe pushes more air then a lot of pipes can handle.
