This is an alternative build for Lego set 42084, Hook Loader. When I thought what to make of it, the two curved panels brought no other inspiration than an airplane. It felt a bit boring at first, but when I started tinkering with it, I realized that it might be a nice challenge to avoid building with straight angles. It’s biggest downside is that some parts stay in place on sheer pin-friction, which doesn’t make the propeller attachment and the connection between the fuselage and the pontoons quite weak. Also, I don’t like the white front windows so much because they look too much like eyes. On the upsides, besides all the weird angles, the tail planes have moving ailerons and the plane has a great whoosh factor. One fun fact about the design: the fuselage only stays in shape because of the axle-pin that connects the vertical tail to the pin-connector next to it.
