Thanks Ron,
I'll check out Hobby people for that price. I want to make an accurate temp check before making any changes but the changes you suggest sounds like what i'll have to do to get the temp down. I'm running 4 degree grips and get a hover at about 50% throttle. I thought about cutting a hole in the wood crutch behind the motor to allow for more air flow.
What is different on your setup ?
