| Re: engine to hot Hi there, just a point, what nitro content are you using ? it could be too low this would make run hot. Is the frame in front of the head of the engine being cut away to give air flow to the head. My raptor 90 has a viper headed os cspec and i had to cut away most of the black plastic frame to get the engine to run well. plus a good fan quick UK do a good quality metal one thats better than the std. gray plastic. let us know if you sort it out.
