Thanks for making this mod, your heli is awesome and fits the game very nicely.

Did you consider adding textures with tilted model? Given that you have the 3D model, just render it with 4 tilts to all sides.

And apply the front and back tilt maps when player is hitting W and S keys.
And the right and left tilt when player hits A and D and the heli speed is > 0.

I think it would make it feel really like a helicopter.

maroder has random tilting animation in his Raven mod, and it feels really like you flying in unstable air instead of rolling on a flat ground.

Thanks! No, I did not consider that yet. It's a great idea and I'll see what I can do. For now I'm working on fixing some nasty issue with inserters trying to insert into the wrong entity tho.
