well i went to my local hobby store and got a few parts to get the truck up and running properly but it didnt work. So... i can run the truck well but if ran i think it will break something. so my problem is that the truck wont roll correctly when i dont press the gas at all. When i do press the gas the truck will move fine and run normally as far as i can tell but as soon as i let go of the gas the truck will come to a stop. when idleing the flywheel is spinning but the spur gear is not. so i was guessing that this might be because of my transmission... If anyone knows how to fix this that would be a BIG help!!need to get some more driving time today if can

!!
thank you,
matt
