The only stealth is the tail and the paint. Not with that big pie hole exhaust. Maybe the wings will be somewhat stealth. One engine not good. A m16 for a weapon. Long time ago I build a stick model sail plane. Powered by an OK cub 409 (I think but can not remember) engine. It had a six foot wing with Dihedral tip wing ends. The tail had a timer that would pop the tail up and cause the plane to circle and crash land. Their as a timer hooked to the gas line that would shut the engine down. Well something did not work out and the plane keep flying. It got in a updraft wind and I never did find the plane. The Dihedral effect in a wind draft will make the plane fly like a gilder. LOL This 401 can not replace the A-10.
