I go back to my original statement then! It's a Traxxas engine and thats what you can expect! That's the number 2 reason I went brushless, number 1 is that brushless is more powerful.

Most likely your mixture is off, go back to the original settings on the carb which I beleive is flush on the low speed and 4 - 4 1/2 turns out on the highe speed needle. Get it running and then tune it again.
