The Stunt plan is of the Pegasus by Jean A Pailet .. it has a 49.5 WS and weighed a whopping 56 oz,, How did a Fox 35 fly a pattern on these early stunters ... that is a mystery to me.. at this weight it would push the limits of an LA46 ..

The FF Plan is of the Uranus..a 1/2A design sporting a 46" WS ... this is from the Outerzone site.."The Uranus is a high performance contest aircraft designed by and
intended for the serious free flighter. The construction is fairly
simple and any average modeler can manage it. Trimming must be precise
and gradual. If you are inexperienced but have flown some free flight,
the Uranus will offer you a thrilling challenge and reward; as it is a
very stable and exceptionally fast model.
At the end of the 1962
contest season, the Uranus was conceived; when we realized that in order
to compete with the high caliber ships brought about by the new rules,
it would he necessary to have a design that would climb very well and
still have a slow flat glide. To obtain this, we decided on a wing area
of approximately 275 square inches, an airplane with little or no
frontal resistance and lightly loaded, coupled with an airfoil with
which we have had good experience and the Uranus exceeded our
expectations.
