Glow Plugs

RC Glow Plugs

Glow plugs ignite the fuel in glow (nitro) engines used in RC cars, trucks, planes, helicopters and boats. There is no spark: a small coil of platinum alloy wire inside the plug is heated by a glow starter before starting, and once the engine is running the heat of combustion keeps the coil glowing.

Glow engines run on a fuel blend of methanol, nitromethane and oil, and the methanol is what keeps the plug working. Plugs are made in different heat ranges, so check your engine manual for the plug it recommends.

Heat the plug for a few seconds with a charged glow starter before starting, and replace a plug if the coil is broken or the engine becomes hard to start. Glow starters are in the Nitro Starter Pack category, and fuel is in Nitro Fuel.
