Tell me if I missed anything

With the recent discovery of hollow concave fuselages, I wondered what else there was to discover:

This is every part in the game that I thought would change graphically if I set a value to a negative number, in other words, pistons and rotators aren't here because I think negative values won't change them in graphics, only in gameplay

I only put the ones I found interesting, but all the parts ARE here, except for the hollow fuselage.

Red: Normal fuselage
Dark Red: Fuselage cone
Orange/yellowish: Wing on bottom has negative leading and trailing edge offsets for all 4 edges, wing on top has that in addition to negative hinge distance
Brownish: Adaptive nose cones, with all possible combinations for negative sizes
Green: An inlet with negative trim size, has a different inside color from outside
Blue: A tire set to -2 size
