Hi Albion,

Just a couple of thoughts on items you have mentioned above, eg the arrester hook wire mechanism & The elevators.

For the arrester wire, you could use something like a fishing reel system with twin motorised spools hidden under the flight deck, the spools will allow a certain amount of cable to reel out freely, but rotated in the opposite direction will have the motors to reel it back in....you would obviously need a right handed and a left handed reel to fix this up. (They are available too)

As for the motorised elevators,
you could build the platform based with 4 nuts, one on each corner, those nuts would lay flat & would be on vertical threaded rods each fitted onto a motor, All the motors would be powered at the same time from a single switch so when the power is turned on, the threaded rod rotates and your platform will move up and down accordingly. You can buy the threaded rods in 4ft lengths in most hardware shops. If you can't quite picture how it works, just look at any sea-drilling rig which uses a similar method to raise and lower the legs to and from the sea bed. They generally use a rack and pinion gear system which is also another way to look at. The threaded rod principle I mention here has been used to great effect on many R/C Jets which use swing wings...eg Tornado, F-14 etc.

At the size ship you are looking at, these should be perfectly viable methods to use....I hope these help.

Regards.........Mark.
