single speed revo with nitro engine

[grenade6]

hey i have a revo runing a trinity draker .28 engine runing 18 bell 36 spur with a 1/8 scale clutch (savage). will i was mesing around i ajusted the trany screw so it would stay in second. well lets just say about 5 min after that my clutch bell was purple and blue and the heat melted my clutch and my spur gear ( didnt strip it but when i came to a stop it melted a notch in it) so i would keep the first gear.
