This is my second adventure with Armattan frames. The first one was Rooster. And it would be great if not moving arms. I yielded again and got me an Armattan Marmotte this time. I recorded this video before flying it. When I write those words I already know how it flies. It flies good, but I still have to tune and update motors to something more modern and not beaten up. In other words: Armattan Marmotte is great in the air but some of the design elements are extremely bad!
