[5] The whole trailing edge of each wing was moveable, the inner third acting as camber changing air brakes and the rest as differential ailerons.
[6] Spoilers of the early, single action Centro Volo a Vela (CVV) type were mounted on the upper wing surface immediately behind the spar and at about one quarter span.
The lower line also required the addition of a very short pedestal for the tailplane, directly mounted onto the hexagonal fuselage.
The horizontal tail was straight tapered and round tipped, placed with its trailing edge in line with that of a narrow fin so that no cut-out for rudder movement was needed.
On the ovoid fuselage version with its small pedestal the fin reached only about halfway to the top of the rudder, allowing the inclusion of an aerodynamic balance.
