So it turns out I've built a new aircraft I'm working on sideways in the builder. I know this as when i go to mirror the aircraft it attempts to mirror it horizontally instead of laterally. The aircraft spawns sideways as well and this wouldn't be a problem if it wasn't for the fact that the game is applying drag to the side of the aircraft I'd imagine due to the game still thinking the side is the nose of the aircraft. This is giving the aircraft such massive drag and causing it to lean to the direction of it making it hard to control.
Have I fucked myself over or is there a way to sort this out without starting from scratch?
