I don't know of anything specific to what you are asking for.   The only way I can think of is to get a kids RC toy, and hack it apart.  

The other route is to visit an RC store.  Talk to someone that knows a lot about planes, cars and Heli's.   They will know if there is a cheap solution to what you are looking for.

The third thing you can try is to get a wireless switch for the power source.   One that plugs into the wall between your power source and the wall plug.   There are plenty of those on the market.   I have a lot of LED cabinet lights and I have a wireless switch for them.
