RE: 3D AIRPLANES DO YOU seal ALL hinge gaps ? PLEASE HELP
As JAS noted - gap sealing is a preferrence thing -If you have gaps -seal em if you like - as for wind tunnel tests - Bull s---.
As for stopping flutter - again Bulls---.
If- the seal is tight enough to restrict free movement - yes it can help reduce flutter .
On my own stuff - almost never exept for my small foam models -somehow I can seem to avoid sealing the hinge line --
