How would I go about creating aircraft?

Hey Developers!

So in my downtime, I decided to start an Airline in Roblox… one of my biggest problems in development, I just can’t seem to figure how to make aircraft… I’ve been hearing to use PlaneKits however I have absolutely no idea how to do this, if you have tips or links to plane kits I can use please leave them in the comment section, your help is much appreciated!

Thank you!
