You'd be surprised.
We are on contract with the Navy for "morphing" wing technology...and other companies are working hard as well.
Screen shot:
We have millions of control cycles without any failures. We fly a small UAS that is completely MFC controlled.
Our next UAS design is a UAS that is stored in a canister and is flown to a drop point on the wing of a jet. Once deployed, it unfolds. It will be 100% MFC.
