Stolp SA-750 Acroduster Too

Designed by Jim Osborne & Morgan Schrack the Acroduster Too, originally called the Schrack-Stolp Super Star-duster Too, is a scaled-down 9/10 scale version of the Starduster Too and first flown in 1984. The Acroduster Too SA750 is a fully aerobatic, two-place machine stressed to plus & minus 9 G's. It has modified symmetrical wings and is meant for minimum of 180 and up to 360 horsepower. It possible to remove the front windscreen, cover the front cockpit with a hatch cover, and add a sliding bubble canopy over the rear hole. The fuselage was also metalized back to the rear of the cockpit.

The optimum engine is the fuel-injected 200 HP Lycoming, with constant speed propeller. The prototype cruises about 160 mph, climbs 2300 fpm, and stalls at 55 mph. Although it has a comparatively sharp stall and sensitive control response, wings can be maintained in the level attitude with rudder alone or with aileron. This with stick full back by reducing power to idle and zero climb until stall is obtained.

Construction follows traditional biplane practices with steel tube structure and spruce wing spars. Ribs are plywood with cap strips.

All materials were available from Stolp Starduster Corporation, either in kit form or as raw materials.
