Im with Metallicajunky, I started with my Wild Hare Baby Edge 540 (1.60 glow size) and have been flying it for three years now. Over the past three years or shortly after flying the Baby Edge 540 I started saving up my money to purchase a 50CC gasser. You can sometimes find really good deals on used 50cc gassers plane engine and all. Well after slowly buying a 50cc plane, chooseing my gass engine, and radio gear, this year I finally get to step into the gas engine world. I hear its like the day when you dad took your training wheels off your first bicycle. and Im looking forward to it. Good luck and have a great time.
