RE: Building the Mick Reeves Hawker Hunter
Here you can get an idea of some of the parts included in the kit.
The first pic shows the fuselage formers, all plywood, and all nicely machined. The fit of the formers to the fuselage is prety good, such that thin CA (or in my case, PlastiStic) can easily hold the formers in place until such time as you get around to epoxying them.
The second pic shows the wing parts. The ribs around the landing gear are again plywood. The other ribs - I've seen Mick refers to these as "lite-ply", but they don't look like the kind of lite-ply that I am used to seeing. The material actually looks more like balsa-ply.
Finally, you can see the landing gear : retract units, struts and wheels. The main wheel tires seem like hard foam, whereas the front tire is a rubber shell with air inside.
