The fireball motor is a great upgrade to the stock 370 can that's in there. The fireball motor is a 370 motor and is actually an upgrade for an electric R/C truck called the 18MT. The fireball motor makes this little truck haul so much speed, it's insane. Glad someone mentioned it because that's the same motor I had already thought about useing as an upgrade. Yes it is very inexpensive compared to brushless setup. It only cost $12 at the hobby store I work at.
