Coaxial helicopter

I have assembled a coaxial helicopter with an automatic skew. It runs on 3-4 coal engines and is controlled using a typewriter. The helicopter is capable of performing yaw, roll, and pitch. When first launched, it will shake until all the mechanical rotors are activated (there are a total of 8 rotors). The optimal speed for operation is 6-8 levels of redstone signal. No additional mods or add-ons are required for the helicopter to function.

When assembling for the first time, activate the 2 bearings under the screws and set the angle for all the bearings on the screws. On the top screw, press each valve once. On the bottom screw, press each valve once while holding down the SHIFT key

Controls:

Space - increase rotation speed

Shift - decrease rotation speed

Ctrl - disable

Caps Lock - enable

Q - counter-clockwise yaw

E - clockwise yaw

W - forward pitch

S - backward pitch

A - right bank

D - left bank
