New Fully Loaded Motor question
 

I just bought the new Fully Loaded Super Slick. And purchased the sl-55 tune up kit with the big blue motor and purple gear. When u flip it upside down.. the wheels screw.. there so fast. Then when i put it on the ground its a put put... really slow. I thought it was the 1/4 mile thing.. really fast and punchy. Any advice.

um try using the other motor and see if its still slow. what you mean by the wheels screw. thats all i can think of.
