CH-54 Sky Crane (Lift >20,000 lbs)

Sky Crane - lift over 20,000 lbs plus! (20K lbs container provided). Very stable for hovering and lowering.

- AG1 and VTOL up to start rotation
- TRIM up for lift (~20% takeoff unloaded, ~50% loaded).

- Roll to roll (good for slow turns)
- YAW to rotate.
- Pitch = nose down/up for moving forward. (Use TRIM to maintain correct altitude).

Cargo Operations:

- AG2 to release cable/cargo.

Alternative cargo lift:
- AG3 and VTOL up to extend clamps.
- AG4 to close.
Sequence: AG3 on, VTOL up. AG4 on. AG4 off, move VTOL down to pull cargo into position, once ‘tight’ AG3 off.

Engines:

Throttle for thrusters: When in flight, one can use thrusters for more speed. Remember to reduce lift (TRIM) as speed increases.

AG5 and Pitch (forward/reverse) for auxiliary engine for ground movement (front wheel only). Turn off AG1 and AG8.

Notes: I tried many swashplate assemblies for this and when load is put on these designs they tend operate erratically and therefore I went for a more basic design.

    @SpiritusRaptor Why does it try to pull the cargo container and explode?

    Fantastic and almost at 100K!

    @SpiritusRaptor Yes, that might be the case. I, myself have succeeded in making a stable 8 bladed system that can lift a considerable amount, however problems also started to occur when it reaches 20,000. The aircraft starts to wobble excessively starting at 18,000 pounds and starts to tear itself apart after 22,000 pounds.

    Hiya, yes I tried about 10 different types and versions of rotors. 4, 5, 6 and 7 bladed, swashplates, and down loaded many, but when the load was being taken up they either became erratic, we'rnt stable and she would move forwards properly... I think its partly due to the use of pistons and hinges in swashpltes that may do this...
