How do I do an flying physic like in "learn to fly"?

Hello, I'm new to construct 3 and coding in general.

I would like to make a game where the main gameplay is gliding through the sky but I can't manage to do a good and fluid physic like.

The result I search is when your glider is at enough speed it goes up depending on the angle he is.

I already try to add force or velocity when I reach the speed, but the result is not great.

Here's the c3p file: gofile.io/d/okz6en

If someone can explain in a simple way to me how I can achieve a great physic that would be great.

I already watched some YouTube videos where people explain how flies physic work in the real world, but I don't see how I can put it in construct.

Thanks

Here’s a rough way to do lift. Basically you find the velocity perpendicular to the wing with a dot product and apply a force from that to do lift. It’s modeled after a lift formula found on Wikipedia. You’d tune it by adjusting the lift variable.

Var vrel=0
Var lift = 0.01

Every tick
— set vrel to sprite.physics.velocityX*cos(sprite.angle +90) + sprite.physics.velocityY*sin(sprite.angle +90)
— sprite: apply force -sign(vrel)*lift*vrel*vrel at angle sprite.angle+90

Wow, thanks you so much.

It works really well, way more than what I was trying.

Since I'm bad with maths I will try to understand the code, because right now I understand just a bit of it.

If you have any tips on how to make physics even better, please don't hesitate, I'm all ears.

I have a little problem. I wanted the player to fall when it close the glidder but when the lift is over 0.2 the glidder and the player is stuck middle air. I think is the lift that do that but I can manage to correct this bug. Do you have an idea what I can do ?

I didn't manage to patch the bug. It occur when the objet touch another one with physic. I don't know why but the velocity switching between positive and negative value and i don't konw why. Here the file if you can help me gofile.io/d/4hgMbO.
