I think the build mode needs some updates

1: you should be able to test rotators, hinges, control surfaces, etc all inside the build mode, so you don't have to load into a game.

2: More visual statistics, seeing where drag is occurring and how much drag, and not just red to white coloration, also of how much lift your getting and where your getting it, like showing arrows going along the bottom of the wing and the top of the wing, red for no lift, green for alot of lift and varys color or even more in depth.

Mostly show more statistics and visualized statistics
