Looks like your all set there, the kit comes with a speed controller. U might wanna invest in a better charger and battery. Maybe a charger that can charge NiMH batteries because those are the most popular. Get a gp 3300 Nimh and a charger that can charge it, then u will be satisfied, basically like anything else, u get what u pay for, so only spending 40 bucks on a batt/charger will probably not satisfy most ppl.
