STOLP “ACRODUSTER 1″€

First introduced in 1973, the SA-700 Acroduster I is a single-seat fully aerobatic biplane suitable for engines in the 125- to 200-hp range. Its fuselage is an all-metal structure constructed from lightweight alloy, and the wings are conventional two-spar structures with spruce spars, plywood ribs, and fabric covering. A unique feature of the Acroduster I is that when the stick is pulled back, all four ailerons are raised slightly to help maintain aileron control when the airplane is stalled in a normal attitude. The opposite happens when the stick is pushed forward to aid control when the airplane is in an inverted stall.
