Hello, Luke100000!

I really like this mod and I have some questions:

1. Could you describe effercts of each modification or send an article when they described? I have tryed to find it myself but I didn't...
2. If we take the power of regular airplane as 1 and we put Nether Engine, the power is 1.4 now. But if I want to put also strong pipes (it increases power 10%) so what is power of the airplane? power = 1.4? power = 1.1? power = 1 + (10.40) + (10.10) or power = 1 * 1.4 * 1.1?
3. Do you need help to translate the mod to Ukrainian language? If you do, I can help your for free :)

Have a nice day

Hi!

Upgrades are calculated here: https://github.com/Luke100000/ImmersiveAircraft/blob/1.20.1/common/src/main/java/immersive_aircraft/entity/InventoryVehicleEntity.java#L84
and are additive, so in your case its 1 + 0.5.
except for negative values (e.g. -10%), it's multiplicative, so 1 * 0.9.

To make math consistent, negative effects are applied first, then positive ones.

So a -10%, +30%, -20%, +40% will be 1 * 0.9 * 0.8 + 0.3 + 0.4 = 1.42 = 42% total improvement

Translations are always welcome, usually via Crowdin :) https://crowdin.com/project/immersive-collection

Thanks for answers for 2nd and 3rd question. Could you describe the "Enhanced Propeller", "Gyroscope" and "Improved Landing Gear"? How they influence on the biplane? Could you describe, please?

Propeller increases max speed, gyroscope disables wind wobbling, and the landing gear increases acceleration on the ground.
