R/C enthusiast and I've been to a lot of his events and it's hard not to charmed by the look of childlike joy on all the racer's faces.
Experienced R/C enthusiasts often find that the most satisfying aspect of the hobby is pushing their vehicles to higher and higher speeds. Small model making is all about customizing components to the hobbyist's preference and skilled racers have gotten their cars up to 50 mph. Before you're zipping around your R/C car, plane, or boat at top speeds you're going to need to know about aftermarket motors.
R/C modeling kits are sold either gas engines. Electric is the lowest power of the three and the easiest for new R/C racing enthusiasts to practice with. Replacing engines is usually as simple as unscrewing the motor casing, removing the wire leads from the car's body, popping in the new motor and attaching the leads, and finally making sure the radio control syncs with the car.
R/C aircraft and powerful racing cars, gas engines have many more parts and require a very precise mix of fuel and a lot of priming and preparation time. There are dozens of enthusiast sites and tutorial videos on gas engines, but the big thing a gas engine racer needs to pay attention to is keeping the engine clean, making sure the moving parts are properly lubricated, and that the operator is using the correct fuel.
