ok i tuned my tornado and change the throttle servo and the spring and throttle linkage. When i give the car throttle and then let go but don't give the car brakes it will keep going at around half throttle from when i give it full throttle and then i have to give it full brake to stop itfrom sticking then the engine dies please help thank you.

Did you center the servo with your remote, I had my buggy do that once. Make sure your servo is returning to idle position when you release the trigger.

on my remote the throttle is turned over all the way to let it id;e should i center it in the middle at idle to get it to re turn to idle after

You need to center your servo dead center with your remote.....put the knob on your remote dead center. Remove the linkage horn from the servo then turn on your remote then the car. That will center your servo. Then make adjustments from there. You should never have your knob on the remote turned all the way to one side.....sounds like thats your problem....
