Onboard Glow Igniters
I am currently finishing a build, a 1/4 scale Sig Cub on floats. The engine I'm using is a OS 160 Gemini twin. I got the engine from a buddy who broke the engine in but never flew with it. He suggested that I install an onboard glow ignition system that would help prevent one or both glow plugs from flaming out during flight. I'm confused, wouldn't constant power going to the glow plugs shorten the life span of the plugs? After all, when we start a single piston engine the first thing we do after engine start up is remove the glow igniter. Can you recommend an onboard igniter that would either provide a low enough voltage that would not compromise the life span of the plugs or an igniter that would shut itself off after the engine is running. It would be very convenient to have onboard glow as security against flame out, if there is such a thing, and ease of starting without having to attach a glow igniter. I'm new to this idea and would appreciate any advise on which way to proceed.
