Helicopter MK1-R11

Helicopter made for Minecraft 1.21.1 Create aeronautics. Not much else to say other than that it is my first shot at making a helicopter, and first time I learned about copycat blocks. Mostly made out of cut deepslate and polished cut deepslate. I originally wanted to build a Huey, but it didn't end up looking very faithful to the UH-1H due to internal size constraints. I still believe it looks alright-ish regardless.

~SPECS~
Drivetrain: 3x portable engines (blaze cakes or jury-rigging more engines is required, 12.5k SU recommended)
Minimum height: ~Y=47
Maximum height: ~Y=220 (note: trying to turn and fly forward at this altitude will overstress the engines, so maximum operational altitude is ~Y=205)
Built-in cargo: 4 chests (2 single, 1 double), 4 barrels (total: 216 inventory spaces)
Maximum safe carry capacity (Y>132) (given cargo is centered with rotor) = 60kpg

~CONTROLS~
(keybinds are for typewriter)
W: Fly forward
S: Reverse thrust (you DO have to press W and S to fly backward)
D: Engage tailprop (turn right)
A: Reverse tailprop (turn left) (as with reverse, you also have to press A and D to turn left)
Throttle: Found in cabin, decrease from 15 to 1 to go higher. Vice-versa for increasing the lever's output.

~NOTES~
- All keybinds come pre-set. You can set the link frequencies to something else yourself, but it works out-of-the-box. Be wary of signal interference!
- The contraption uses superglue, meaning that you will have to make superglue to use this build (by either killing slimes or using dyes and dough), or modify it yourself with honey glue if you want to make this in survival.
- MK1-R11 means "Mark 1, 11th revision)

~KNOWN PROBLEMS~
1. The gearshift and clutch for the rear propeller are exposed and not covered with boards in the .nbt, I only noticed only after I started taking pictures after uploading the .nbt
2. The engine overstresses when going forward and turning simultaneously at max throttle.
3. The front doors use trapdoors, which make getting in/out using the front doors tedious.
4. The helicopter goes to the side slightly when going forward
5. The maintenance access trapdoors for the tail propeller redstone links open due to impulses from the redstone links themselves, TLDR pressing A and D causes the rear trapdoors to open and close.
6. The creation uses intermixed copycats from both Create: Connected and Create: Copycats+
