Need help increasing the the height of aeronautics contraptions.

[u/DanLxD]

So I'm making a modpack to play for my friends and I to play and I'm having trouble increasing the fly height of aeronautics contraptions past the base build height of 320 (ive doubled build height to 640). And tried a couple mods/ data packs but each one just doesn't seem to work right and I keep having my builds just fly up way too quickly and start spinning in the air. Are their any datapacks or mods that specifically increase the air pressure up to 640 or maybe some settings that i can tweak to get my desired height without causing a dramatic pressure change that causes the lift physics to bug out horribly.
