Need to find something new.

Option one:
If RC is boring you at the moment, sell the vehicles but keep the tools, chargers and stuff like that. The reason I say that is the vehicles are probably out of date or will be in a short while but the tools are always useful. If you ever want to get back in RC then buy the vehicle that is popular at that time.

Option two:
Keep everything you have and have fun with it from time to time when you feel like it. Don't neglect the stuff you have though, keep maintaining your RCs so that they are in good shape.

Option three:
Get into some RCs you never had before like airplanes or boats. Or even a Monster truck.

There might be other options for you but I am tired of typing. Whatever you do, just have fun with it.
