I've still got the one I ran all last year, and distinctly remember it coming off the track at Cotswolds 115°C every single run... still didn't fade, and still runs strong!

I disagree ... any engine should not exceed 80°C, if you want to keep the maximum performance, I personally saw a rotor a rotor x12 unhitched ...
Also for GM the temperature limit is 100°C, same as LRP, but personally I advise you not to ever get there.
