raise the idle. Nitro engines tend to run on the fast side when cool but when it comes up to temp it will kick back down

Did you try and lean it out, You mentioned that you richend it up but if you have fuel that is unburnt coming from the exhaust then that usually indicate's that your to rich. How many gallons have gone through that engine, and is the enigne up to temp when you try and do these high speed runs. Also you can try another glow plug and see if that helps a little, or try and clean your air filter.

i would lean it out but is real hot after just 30 secs of running to hot to touch and then it loses power and dies but is blowing a lot of smoke it will idle for a long time with no probs the motor has only had 15 tanks thu it at the most
