Thank you.@Skua

@Wanley the tilting of the wing is called the angle of attack

@Wanley in real life terms, the airfoil is the shape of the wing's cross-section. If you got a wing and cut it in half from front to back, then looked at the shape of the face left by the cut, you'd get something like these:

The cambered one is basically the same as what the game calls "semi-symmetric"

Is it the tilting of the wing? @skua

Lol u sure do a good job in helping people, but I may seem dumb by asking this but what is an airfoil?@Skua

@Wanley sorry, I get worried that I'm not explaining myself clearly enough and ramble on too much haha

Thanks for the help, i didnt expect an essay,but thanks for taking the time for helping. :)@Skua

Also this was my favourite one, nice work!

Okay so I tried out all of your planes. It's pretty cool to see you improving from your first one to your most recent one. The two biggest things I'd say you could work on are airfoil types and the relationship between CoM and CoL. Airfoil types are found in the settings for wings, and they affect how much lift the wing produces when you're flying straoght and level. Symmetric produces none unless it's at an angle to the air flow, semi-symmetric produces some, and flat bottom produces a lot. This is mostly used for making sure you plane hold level when you don't touch any of the controls. If your plane noses up a lot (this one does), use an airfoil type with more lift near the back - this forces the back up and counters the nose-up tendency. The CoM and CoL, or centre of lift and centre of mass, are the biggest things that govern the stability of your planes. Most of your planes are actually much too stable, and as a result they struggle to turn or lift off. The closer the CoL is to the CoM (the blue and red sphere respectively), the less stable your plane will be. Having the CoL in front of the CoM makes it completely unstable. Try to adjust your centres so that lift is fairly close behind mass, and your planes will handle a lot more nicely.
