A rebuild of my first take on the airship Tiger Moth, from Laputa.
Some of the changes: I replaced the landing gear with struts, which seemed more appropriate; I reorganized the action groups to help prevent accidental explosions; adjusted trim and ballast; added three flapttors to the cargo bay (non-functional, sorry. There are not enough action groups!); completely rebuilt the glider as a powered plane; fixed minor camera and cockpit view issues.

Below are operating instructions, in this format:
Controls: Result

Roll: Rudder (yaw) + minor roll effect for stability and realism
Pitch: Elevator (pitch - internal gyros have a governor in place to prevent flipping the airship upside down)
Yaw port: explosion, probably
Yaw starboard: open cargo bay doors to reveal flapttors
Throttle+AG3: throttle wing-mounted props
Throttle+AG4: throttle centre-mounted props
Throttle+AG7: throttle powered glider prop
Trim: adjusts trim of wings for powered climb and descent + adjusts trim on glider elevators
VTOL up+AG1: adjust ballast (throttle internal jet engines for lighter-than-air flight. Full up = slight positive buoyancy.)
VTOL up+AG2: stow landing struts
VTOL up+AG5: Unfold glider (full up for stable flight)
AG6: detach glider (detaching at full speed will result in a clean launch, after which glider will assume a relatively stable unpowered flight attitude)
AG8: disable all pitch, roll, yaw, and trim controls for Tiger Moth (useful while flying the glider)

Cameras:
Camera 1: forward lookout (above cockpit)
Camera 2: glider chase cam
Camera 3: glider cockpit cam
Camera 4: flapttor bay
Camera 5: aft deck

Notes on Tiger Moth:
Adjust trim down slightly when at full speed for level flight. Should be able to make around 90 knots. Trimming full up or full down will result in minor yawing to port. I had to do some weird stuff to the drag scaling in the wings to get a nice straight level flight, and that was the trade off. I'm working on the next version, with actual cabin, galley, and engine room internals, but that's a ways off. And yeah, I know there's supposed to be four flapttors - my proportions aren't perfect yet, but I was striving for scale based on a standard cockpit. I don't much like using an infinite fuel hack, but having to use jets for a lighter-than-air effect pretty much mandates it unless you want a very short flight time and a lot a ballast adjustments.

Notes on the glider:
I opted for a plane rather than a kite because it's more fun and because I had a devil of a time getting a kite to work without stupid gyroscopic shenanigans and cables getting in the props. Very fast and maneuverable when throttled all the way up. Trim up a bit when under power, down a bit when gliding (I had to mount the engine above the center of mass because of some obvious design constraints, but I think I found a happy medium). Landing gear allow for runway landings and takeoffs, and a buoyant bottom and wingtip floats allow for very careful water landings and takeoffs. She has a ridiculous glide ratio. As a separate craft, the fuel in the wings is enough for a good long flight time. Unfortunately, the game doesn't recognize separate fuel sources, so you've got the Tiger Moth's infinite fuel reserve to play with instead. And no instrumentation, obviously.

TL;DR: throttle full up, VTOL full up, then activate action groups in sequence from 1 to 7, pausing to observe effects. AG8 will disable TM controls during glider flight.
