What are the differences between a Nitro Sport and a Nitro Rustler?

The Nitro Sport is designed to be an easy entry into the nitro R/C hobby. It has a TRX .15 engine which features single needle carburetor adjustment. This makes it a snap for most beginners to learn how to run and maintain it. Nitro Sport's chassis is a mix of composite and aluminum materials. It also uses a simple direct steering mechanism, and has a top speed of around 30 MPH. The Nitro Rustler is the big brother to the Sport and features a high performance Pro .15 engine, bellcrank steering system, full aluminum chassis, and adjustable slipper clutch. The gearbox, suspension, and shocks are the same on both trucks. The Pro .15's larger, 2-needle carburetor and larger cylinder head propels the Nitro Rustler to top speeds of over 40 mph. Due to the increased adjustability and speed, the Nitro Rustler is better suited for more experienced enthusiasts. Both the Nitro Sport and the Nitro Rustler are now equipped with the EZ Start™ electric starting system.
