Hello all!

I am a novice with Xmods. I recently ordered my first Xmod car!.

Well i got it about 2 days ago, played it for a few hours and found it to be amazing!

Well after racing it, i decided i wanted to upgrade the motor.

So i went on this Xmod UK website and ordered a stage 2 red drag motor. The motor came...but with no instructions, but that's because i ordered the motor on it's own (not the offical set of 4 motors).

But i found a tutorial on the internet and installed the motor correctly...but when i started to race it, the car kept on stuttering while i was accelerating!?

I don't know why...can someone help me?

I also phoned up my local model shop and they said it probably is stuttering on acceleration because i have no heat sinker? Is this true?

What parts do i need to make it work? Or did i install it in-correctly?

Btw i have an Evolution 1 Stock Xmod car - this one - http://www.modelsinmotion.co.uk/product.asp?productid=17920&catCode=539&...

Someone please help me!

Thanx! :)
