FAQs About RC Plane Engines

Remote control planes allow you to experience much of the excitement of flight without actually becoming a pilot. More than just toys, remote control planes are used in competitive and display settings as well, and are a fun hobby for both children and adults. There are two main types of engines that power these small planes, and each has its own distinct strengths and weaknesses.

Q: How do electric motors work in RC airplanes?

A: RC airplanes are frequently powered by electronic motors. These motors are typically powered by a rechargeable battery which is charged when plugged into a standard wall outlet. The engine has a rotating post that sticks out of the front of the motor and is inserted into the plane's main propeller on the nose, which powers the airplane's movement. Electric motors are typically preferred for RC aircraft because the battery power is lightweight compared to gas fuels. An electric motor is quieter, easier to control and has a longer flight time than its gasoline counterparts, but it is also slower and less powerful.

Q: Are gas motors ever used in RC planes?

A: Yes, some larger aircraft do use gasoline combustion motors as their power source. A gasoline powered motor cannot carry too much fuel or the aircraft is weighed down, so most gasoline powered remote control vehicles can only run for about 15 minutes before they must land and refuel. These motors are capable of significantly higher speeds than electric motors. They can go up to 50 miles per hour, if controlled well.
