Hello,

Few weeks ago i purchased a GST 7.7. I ran three tanks of gas through it and then started playing around with it in my parking lot. At first, i was having a hard time getting the truck to move. With the controller in hand i could hammer it down and the truck would rev up like it was going to move and it would move... just about three inches... and stop. So, i started leaning it out thinking that it might be getting too much fuel and it seemed to be helping. However, tonight i got out again and start playing with the truck and it is doing the same thing. I can hammer it and it will rev up and stop. What is causing this? I need help!! Where do i look/start??

Also, the breaks are somewhat stopping the truck now, but not what i would expect. I expect the truck to do a nose dive when i apply the breaks, this isn't happening. When applying the breaks, the truck will stop, but by no means is it immediate.

Thanks,
Magikman
