MMM getting HOT!

[Jahay]

neil.. thanks for taking your time to explain this to me... It really has put things in perspective... I tried doing my reading and asking people what would be an ideal motor that would meet my expectations. I guess i am pushing it a little too high.
I was originally wanting to go for the 1518 but due to having no motor at the time and no 1518 in stock anywhere... i went for the 1520.
I have a few gearing options... I will chuck my 17t clutch bell in there first... with the rc calculator it will bring the top speed down from 75mph (very unrealistic, i wasnt even aiming for these speeds) to 60mph... if its still running too hot. I will take out the the high speed idler gear and put the stock one back in and run the 21t pinion which should gear me for around 50-55mph... I will just watch my temps and gear accordingly.

I am going to work out a way to try and cut weight on my truck... At the moment its only weighing 1 ounce heavier over stock. each wheel is 10gram heavier and the tvps weigh only very slightly over stock. Thats the only weight i have added. (maybe the motor too)

Anyway i really appreciate your help! I will get back to you and tell you what happens.

THANKS!
