I tell people that are just starting out that electric isn't a bad idea but the start up costs can be steeper then glow. I have friends that have never figured out how to set up and tune a glow engine, one friend had gas and glow and sold all his engines and went all electric, even with his giant scale. I have no problems with dead sticks in gas or glow and have all the support equipment so going electric for me would be silly, I do have one small electric.
If you don't know how to tune a glow engine it's best to have someone teach you, even then some people can never figure it out.
