I'm flying my current 4-Star 120 with an Evolution 30cc gas engine on it. I love the gas economy of it and not having to pay the high prices of glow fuel. It's got a 14 oz tank on it and with that I can easily get in 3-4 flights, depending on how long I fly each flight. I've had bigger glow engines in the past (larger than 1.20 size), but those days are over for me. With the cost of glow fuel I simply can't afford to have a fuel hungry engine like that!!!!
