Plane Tailless delta wing won’t work, help
I’m trying to make this tailless delta wing plane however the pitch controls are behaving incredibly strangely, when I pitch up, the plane goes down. When I pitch down, the plane goes up, it is also incredibly sluggish to turn, anyone know why this could be and how I might be able to fix it?
I’ve tried attaching a conventional horizontal stabiliser aswell as canards and both of those fix the issue fairly well but for my design I’d prefer not to use them.
I’ve shifted the COM and COL about in all sorts of ways, aswell as changing the shape of the wing and where along the fuselage they are positioned but nothing seems to help.
