Hi all. Please can anyone help. When I turn my control and car on everything seems too work fine. But if I turn off the control .about ten seconds later the car just goes off on its own full throttle and won't stop untill I switch control bak on or turn car off. I have a castle sidewinder est combo with a fs gt3c which I brought secondhand.
im a new to RC cars and have tried searching but can't find anything.

Thank you for any help
