Chadwick C-122

The Chadwick C-122 was a single-seat ultralight helicopter developed in the United States in the 1980s. It was a minimalist design consisting of a fibreglass shell enclosing a truss structure to which the engine, rotor mast, landing gear, and pilot's seat were attached. A wide variety of roles were envisaged for the aircraft, and therefore it was equipped with attachment points for spray bars, a cargo hook, external cargo racks, and even weapons for law enforcement work. The skid-type undercarriage could be quickly fitted with wheels for ground-handling, or floats for operations from water.

gollark: I think that might be allowed too, actually? But you need to be in some sort of training thing.
gollark: You are not, apparently, legally allowed to do full-time work until you're 18, and must be in education/training of some kind.
gollark: It looks simpler than your diagram, although I suppose that covers all school stuff while I'm only talking about my specific school and there are other options like vocational training of some kind.
gollark: My school has some convoluted thing where for A-level (high school, ish), as well as the regular 3 A-levels, you *also* have to do two of these three options:- EPQ i.e. a big independent-research-y project- a bunch of 3-month nonexamined "carousel" courses about random stuff like sign language and cooking and photography- a "complementary studies" course, which is *either* a nonexamined random thing or something like one AS-level*or* a fourth A-level.
gollark: Hmm, that's quite a lot longer than "high school" here.
