Guys, I met a fellow this past weekend who says he has had great success converting weedies to glow. He said he makes a glow plug adapter, hub for the prop, replaces the o-rings/seals with some that are compatible to glow fuel, removes the flywheel & mag, and may or may not replace the stock carb. I'd like to try this on my next big plane, and I'm thinking of a 31-36cc ryobi or mccullough engine. It seems that although the fuel would cost more, it would save a lot of weight without the stock or even an electronic ignition, not to mention the savings over buying a large glow engine. Anyone have any success doing this? Sound stupid? I'd love to hear some qualified opinions!
