Hi,
I'm just a few months into the gas world and really am loving it! I got a used WM extra 300 PW with the zenoah G45. This is an excellent first gas combo for me and the engine runs really good, is easy to start and has never given me problems. There is a man in our club that has the taylor craft arf with the zenoah 23 and he has a blast doing all sorts of scale manuvers and really floats in for a landing. What ever you decide, it is really fun and less equipment and less mess to clean up.

HTH

Joe
