When Great Planes acquired the Andrews line of R/C aircraft, only the actual engineering of the kit was changed for production reasons. The outlines and airfoils did not change one bit. The Great Planes versions flew exactly like the Andrews versions.

The kits went out of production because people stopped buying them. If there was enough demand, they'd still be in production. Even kits like the Great Planes Super Sportsers and Ultra Sports had to go out of production because of low demand. The people who are spending the money are spending it on ARFs, which is why there are so many of them.
