Thank you very much for your response, Bruce. I am flying mainly electric. Now I have the Edge 540, Cap 232, and my latest addition is the Yak 54 120e, all from Hyperion. I don't really know whether I'm still considered a beginner or intermediate. I've built only ARFs and had flying experience for only a year. I'm trying to fly 3D manuevers now and have succeeded some, and failed some. Now I'm interested in getting a biplane, but afraid of flying without any knowledge abt it. We don't have any airplane experts here in Thailand, that is why I went with the EP instead of GP. And it's hard to get tips and advices from people who somewhat have experience. So, thanks again.
