Very fast small airship (steam)

The case was taken from Qwsxlt
(https://createmod.com/schematics/airship-akis)

This is a small airship designed for exploration, adventure, or fast movement between bases. The airship reaches a speed of 88 m/s, the air balloon lifts it to a height of 200.
The airship can rotate its propeller by 45° and 90°, which allows you to control the altitude. Using the altitude sensor you can climb to a fixed height and hover to park on a flying island (disable this function by removing the redstone link from the altitude sensor, or switch it to reception mode)

The airship is powered by a steam engine and consumes approximately 270 coals per hour, one full chest of coal will keep it running for 12 hours.

Assembly instructions are provided in the video. I can't describe it in words, because the physical bearings cause a lot of problems, and the circuit can't load the full setup, so repeat my steps in the video to avoid problems.

W - Foward
A- Backward
S - Left turn
D - Right turn
Arrow -> turn to the right on the spot
Arrow <-turn to the left on the spot
Shift - 45° rotate (Tap again to turn back)
ctrl - 90° rotate (Tap again to turn back)
left throttle lever - speed control
right throttle lever - high control
Mid lever - turn on the propellers (I left it for flying without your direct control and for hovering in the air when using the altitude sensor.)

P.S. If you want to disassemble this thing, then first you should disassemble the propellers, and only then the ship itself, otherwise the physical bearings can literally break everything.
