@Jasperjl You're welcome

Thanks!@JovianPat

Did you mean Symmetric? XD
Symmetric : Provides no lift in the air. Good for vertical and horizontal stabilisers.
Semi-Symmetric : Provides slight lift, especially in high speed. Use for primary wings, but DON'T use for vertical stabilisers as it'll make your plane unstable.
Flat Bottom : Just like semi-symmetric, but provides even more lift. Use this if you want to make a slow plane, like a glider. This also reduces speed, but very slightly.

Thank you :)@DanAviation

@Jasperjl semi symetric provides lift even on air

@Jasperjl np

Thanks@TempestAviation

i only know that flat bottom means it provides lift when the wings bottoms are facing down. i think
