A variety of Traxxas trucks are available in both electrical engines and nitro engines (nitro is an engine powered by fuel that contains a combination of nitromethane and methanol). Both types are frequently used for outdoor fun, as well as in many amateur and professional R/C racing competitions. However, choosing whether or not you would like an electric or nitro truck is only half the battle, because each category contains diverse machines that differ in their shapes, sizes and performance.
