I'm flying a 110 and have for several seasons. I have to say that I'm happy with it. Some have had issues with BME engines, but the only problem I've had was with the Falkon ignition system. The 110 now has an RC Excel system installed that I got from the new BME folks and it's running well. I also have a ZDZ 100 that is running very well, so I would say make your choices and take care of those engines.
