Hi guys im new to this, bought a lunchbox for a few laughs. But some time when i try to accelerate the hole car jumps and doesnt move forward. Its like it jumps from to much torque. It moves forward if i push the throttle slowly but if i go full wack it just jumps and moves about an inch.

ANy ideas? Maybe a problem with the electronic speed controller or the radio reciever not be the most compatable?

Any suggestions would be appreciated
