You guys are kidding about the RF interference right? Seriously, if you don't do anything dumb and follow the simple rules of engine and servo installation you will never get interference. If you range check your airplane like you are supposed to do you would catch it before you crashed an airplane. An airplane that does not get RF interference won't just suddenly get it years later unless you do zero maintenance on your airplane and have things falling off of it.
I have been flying gas engines for 20 years and have never encountered RF interference from my ignition. IMHO RF interference does not belong on the list as a usual problem or risk.
I agree. I currently keep 7 gassers ready to fly at all times. I don't even own a PCM receiver. I do all of my flying with PPM/FM equipment and never have glitches.

Advantages with glow engines are
More power
Lower weight
Usually cheaper to buy
Smells good when I fly and I can store them in my basement without my wife killing me
The engines looks better and are smaller
No risk for RF interference caused by the engine
More power, you are probably correct if you are talking about 10 - 20 cc engines. If alky engines are more powerful then why don't we see them in 1/5th scale warbirds or 100" ws 3D airplanes? They also gobble great amounts of $15/gal fuel.
Lower weight, have you looked at the weight of BME 110. You are probably right if you are looking at little 10 - 30 cc engines.
Cheaper, have you priced a Super Tiger 3000 lately?
Smells good, I can't smell my plane when I fly. Don't you just love the smell of gasoline in the morning?
The engines looks better and are smaller, have you ever looked at a BME 110? It's a tiny looking engine producing over 10 hp. Looks is in the eye of the beholder.
No risk for RF interference caused by the engine, see above.
It's all from your perspective. To each his own.
