It has retractable landing gear under the cabin and the wings.
Initially I planned for working ailerons and a tilting wing-engine structure. The vertical stabilizers still visible at the back would have served as feet in the tilted state. However the wings were too heavy to mount them rotatable. With turntables it might have been possible. So I went for the retractable landing gear function instead. But the attachment of the wings is still not very stable.
