Ok I’ll make that cargo plane txh very much for the tips :)

Will you be doing the cargo plane that comes with this one?

Always a fan of hotwheels. I see you're just getting started, and buildingon ios. You shouldswitch to pc asap. But in the meantime, Here are a few tips.
When building with a physical reference, such as a model, find a way to measure it to make it look how you want. I used to use maseto tailwinds. I would use a ruler to measure the cockpit, and then build the rest of the plane to that scale.
Don't worry about detailed cockpits. Stick to basic cockpits, and always us two to make a canopy.
You can make them look even better by making whatever fuselage piece they're attached two one click lower on the height, attaching them, then going back up a click.
