Hello; I stopped breathing for the last few metres of the takeoff! I can't imagine flying a model that big. Awesome model and so glad people build and fly these amazing aircraft. Stumbled on this by accident, but couldn't stop watching. Amazing. The sound, the size, the skill building and flying, absolutely incredible. This excellently crafted scale model still carried all the breathtaking awesomeness of the real thing, despite the slightly hard landing! The majesty of this engineering masterpiece never ceases! So every bump on that grass runway of just a centimetre, would be like putting a 16cm high lump in the real aircraft's run way. I'm pleasantly surprised they managed to get it off the ground, and not at all surprised they had trouble with a smooth landing.
