It's been longer than 5 years since I looked at nitros. Back then the top speed was 88 for Nitro and 161 for electric. Nitro really needs a CVT to make use of the power they make. They were just coming out with a 3'speed transmission and they need about 10 speeds the powerband is just too narrow, it's like an Indy car engine. I tried to use a 2 speed transmission from a Jato and a Castle 2650 motor and Mamba Monster and ate the transmission up on the 3rd pass. It was kinda cool having a 2 speed, but when it shifted I would have to let off its hard to go full throttle with brushless electrics anyway. I should have used a 36mm motor instead. But with my reinforced Rustler transmission with steel idler I was able to hit 89, get a little air under the body and it's all over and flys into the air.
