How do I make a remote controlled airsoft gun?

Well, first off, they do sell airsoft tanks, that fire remotely.

but, to do it yourself, I'd say you would need quite a bit of experience, building a servo motor to fire the gun, and figuring out how to remotely control it. As far as that last bit goes, I've seen r/c cars with buttons that activate lights and such, perhaps wire the switch for the servo motor to turn on when the button is pressed

Really though, RC airsoft tanks are inexpensive and would save you a lot of work
