Aerobatic Biplane Ultimate
Self designed for german league F3A - X

Source of the plan of this Ultimate, which was published in the German Model Magazine Modell 6/91 (Report)
was the TOC-aircraft of Bob Godfrey. The design is similar to my F3A aircraft Matador
where the Balsa/Styro-Design Features were first introduced. The structure of the fuselage results in a square frame center,
which is coverd by balsa / styro sandwich components.
Technical details
The tail is completely built of Balsa.
The wingsa are built in conventional Balsa/Styro.
This gives you in a very short time a aircraft with very low weight
with impressive aerobatic behaviour.
