FWIW, glow isn't that complicated to do. You do have to learn how to tune an engine, and cleanup is a chore you have to do. The only serious drawback, IMO, is that if you don't fly much your fuel can go bad in storage and the fuel passages in the engines can get gummy after a year or so. Batteries on electrics can go bad in storage too, but generally speaking your electric planes are perfectly happy to sit 4-5 years waiting to be flown and will start right up when you're ready.
