This is Big John. Plans by Bill Northrop
and scratch built. The plane has 1500 sq. inches of wing and is powered by
an OS 91 Surpass four stroke engine. It has over 200 flights with Ken, the
barbi doll, as the pilot. I recently added a smoke systems to "Big John"
and it flies well. Total weight is 15 pounds. Heavy for a OS
91 and Ken has to sit out as the pilot. You have to fly it like a real
airplane...
