nitro newbie need advice
hello to any one who reads this i have just bought an xb8 and have an sh .21 engine in it, but am having trouble keeping it running on the track as it is a tight and lose gravel track i have traction problems any advice there?
but as far as the engine is concerned i can tune it right to run without the body shell cover on it but as soon as i run it with the body cover on it seems to struggle at the bottom end until it hits top end though i need good low end punch for the small tight loose track any engine advice is much welcomed thankyou ..............Aaron.
