An electronic ignition system accounts for this and adjusts the timing The speed of the engine changes, the precise time that the spark plug shouldįire for optimal performance (in relation to the piston’s position)Ĭhanges. Timing of the spark is critical for maximizing the power from any engine. This eliminates the need for an on board battery. To create electrical pulses for the spark plug at precisely the right time. A magneto uses magnets attached to the rotating engine There are two types of electronic ignition systemsįirst type is a magneto. Weight and complexity to your airplane need to be taken intoĬonsideration. Provide electricity to the spark plug at precisely the correct time. For this reason RC gas engines require on-board ignition systems which Generally when your airplane is around 10 lbs or larger it becomes moreĮconomical to use a gasoline engine due to the cost of fuel.Īre you on the fence between which type of engine to use? Let’s talk about some of the additional components and characteristics that true RC gas engines have that make them different from glow engines.Įngines use spark plugs whereas nitro engines use glow plugs to ignite the fuel/air There are many things to consider such as the added complexity,Ĭost, and weight of an ignition system.
