This. THIS. Is a satisfying build. It’s mechanically sound and well designed, especially visible in the legs when transforming. The most intricate components of the mode are the wings, which between the two of them and the backpack use over 70 individual pieces (if I remember my count correctly) all interlocking and layered to still maintain the flattened form of the original design. There are points to improve, to be sure, namely the kneecap which dislocates during transformation, and the delicate claws on the forearms that don’t have any one position they fit into. Overall, it’s a strong design, highly detailed, well thought out. Definitely worth the money and definitely worthy of being a Master Grade.
