I am new to RC cars I recently purchased a car. I took the wheels off and upgraded some parts to the car. Now even when the wheel nuts are well tight they come loose when I drive the car. Which has meant I have lost a lot of pins from inside the wheel. Is there are solution to this? I read that some people use nail varnish or blue loctite to keep them in place but I guess that may cause problems when I need to change the wheels. Any help would be greatly appreciated.
