Helicarrier

Large aircraft carrier that flies :)

Main Info and Carrier Piloting:

The planes use a locking mechanism that doesn't have them actually connected to the main craft, just held in place. Two pistons extend from the tail when it is inserted into the port. The planes will stay in place as long as you don't do any crazy maneuvers (hard to do cause the craft is really slow) or hard landings (only land on water). To land, slow down laterally, and pretty much let the craft fall (slider one down to negative if it's falling too slowly. It should descend slowly on no engine power.
The craft uses a gyro and rocket engines for flight. Rocket engines can also be used on water. Tilting the carrier slightly forward while in the air will make it move forward. Same thing for going backwards/slowing down. The carrier is capable of going to space, although this is not recommended. Do not attempt to move the planes while maneuvering the carrier; unless the carrier is climbing straight up or moving very slowly, the inertia will cause the moved plane to hit the ceiling and do other crazy stuff.

Plane Info and Piloting:

The planes are each modified KHI-1's. They all have folding wings and a dock/lock mechanism in the tail that allows them to lock in place on the makeshift docking ports. To unlock a plane, click anywhere on the plane, switch to its command pod, and deactivate AG 1. To move around the hangar, the two front wheels are motorized (slider 1) and steerable (yaw controls). To unfold the wings, deactivate AG 1. Wait until above deck to do this. Use the ramps to go above and below deck. If the wheels aren't giving enough pull up the ramp, use a little thrust from the prop.
To relock the plane in place, go back below deck (wings folded), and back the tail end of the craft (with AG 5 deactivated) into one of the little ports. The wide opening should make the job easier. Only attempt this while on water, or very stable flight. Simply switch back to the carrier or another plane when you're done.

P.S., if there's too many parts, get rid of some planes, they make up most of the parts. Having only 4 planes on board brings part count down to like 555.
