The Nitro Star F3.5 engine provides the grunt needed to get the Trophy 3.5 buggy up to wild speeds - it's loud, it's powerful and it's strong, so you'll be able to rip off huge stunts like record-setting long jumps, backflips, tall jumps, even double backflips! The F3.5 engine will give you eye-opening acceleration and crazy top speeds! The engine is started by a simple pullstarter system and is protected by a
unique water splash cover and 2-stage air filter for extra protection, and the two-needle carburretor allows you to fine-tune the performance for any kind of weather or fuel.
One added benefit of the Nitro Star F3.5 is that it's a race-legal .21-size engine, which means you can drop down to your local track or club and enter in a race as soon as you open the box!
