Just one of the videos that I made of my friends and I driving our R/C (radio controlled) Traxxas Revo trucks. They are powered by a .18ci (3.0cc) nitro-methane powered engine that puts out 1.9hp and can rev up to 40,000 RPMs. They weigh about 10 lbs and reach speeds of 40 MPH. The blue truck is mine. There are some front, double and triple back flips in some of the videos.
