I've made the plane and started a cockpit but I can't figure out how to shape the fuselage around it. If anyone can help me I'll credit you when I upload the craft. My discord is BravoLima2k4#9779, so just message me and I'll give you the link to the file. Thanks!
Perhaps this can help
Blueprints are a good start, mate. Then use slicing to match the outline of the canopy (if the canopy is external). if the canopy/cockpit is internal or more inline with the fuselage, just slice that area out!
.
Another thing, if you use the first method, I'd suggest making the fuselage larger than needed and then slicing it down
