RE: CEN engine in REvo
well everything is possible but i think you willget much better results from a high power .18 or even a nice .21 plus it will be 10X cheaper as you might not need to buy all new gears and to replace all the broken parts... that engine is a monster and i can see it making the revo handle like a dog on lino
at the minimum i can see you needing totally custom motor mounts, and lower gears because that engine wont rev anywhere near as fast as a small engine like in the revo [:'(]
