Mine is high voltage spark ignition and has a spark plug.
You can now buy glow plug petrol engines but they are close to $1000 (Australian) There are some reasonably priced glow engines out there but once you go to petrol there is no going back. LOL. Saito also make excellent glow 4 strokes.
I tried running mine on a (special) glow plug without the ign system and it ran quite well but idle was a bit unreliable.
I have a FG-11C and a FG-14C, both 4 strokes. They use very little fuel. I can fly for an hour on about 8 oz of fuel with the FG-11. I flew 4 times on Saturday on one tank.
Glow fuel is getting quite expensive and very hard to procure nitro methane in some countries. Hence the popularity of petrol engines, albeit a lot more expensive initially than a glow engine. Running costs make up for that.
I might add that the Glow Plug Petrol engines have a special platinum element that causes a catalytic reaction with the fuel to help keep them hot.
The oil mix in the fuel goes through the crankcase to lubricate the conrod and bearings. There is a crankcase drain nipple for excess oil.
The petrol carburettor has a built in pump unlike the glow engines. A new carb is around $200.
My next engine will be a 3 cylinder radial petrol 4 stroke 19CC. There are 5 cylinder radials as well and in fact pretty much anything you can think of.
