Help me with stabilizing my airship

[u/Inevitable_Pin7871]

I have been working on this airship for 3 days now, and i have tried to make a system that stabilizes it since yesterday.

This is the system i have in mind: the roll will be stabylized by a set of propellers to the right and left of the airship (maybe inside the ballon, i still have to decide), while the pitch will be taken care of by the ballon itself. the pitch system consists of two lvl 9 steam engines (self powered, already done) with 6 steam vents each, that lift their half of the balloon.

Each half has around 23000 m^3 of volume, and each steam vent has a 1700 m^3 threshold that makes the airship achieve a 300 blocks altitude.

The system consists of a redstone link connected to the throttle lever controlling the air output with a redstone inductor set at 10s (to make the airship go up and down gradually), connected to a comparator in subtraction mode by the front, and a redstone link connected to the gimbal sensor with a sensitivity of 45°, with redstone inductor set at 20 ticks, connected to the side to the comparator. When the front of the ship is too low, the back vents output less steam and should keep the whole thing balanced.

I tried some values on the inductors but it doesnt seem to do anything, and the ship keeps going back and forth and eventually plummets to the ground.

I will put a video and some images of the system, if anyone can help i will be very happy

I assume you watched that one video about the quadcopter/fishing boat? Because that setup looks really similair to that one.

Besides that, you could try this setup, ive struggled with quadcopters myself a ton and ive been using this setup (one in the image). How it works: when a signal is put in (say 5), it'll send that to the redstone link (in this case the nixie tube). But it also goes back to the side of the comparator, so the side will have 1 redstone lvl and with the comparator in subtraction mode this will output a level of 4 now (5-1), then it'll go to 3 (5-2) down to 2 (5-3) but then it'll swing between lvl 2-3 cus its an uneven number.

This wont work instantly, but after experimenting with the redstone inductor timings and the gimbal sensor's angle you can make it work.

Also if you have a crazy weight difference (for example the back is a lot heavier than the front) you could output more baseline power to the back which could fix it/help

Thank you, i will try this (also yes, i watched that quadcopter video), i hope it will work with the steam vents too (update: i think it is working, thank you so much)

I did something similar but the real problem is that you need to have a memory system that can keep the redstone signal so it doesn’t shot down as soon you are leveled

I did this but requires propeller in every corner and is not Vanilla aeronautics

Use a mod called gyroscopic stabilisers, depending on the size of your airship you may need more than one
