The 1931 Stone & Fry S-2 registered N10642 c/n 4 was a single place open cockpit monoplane, powered by a 120hp Anzani engine.

Stone B-2
In 1931 Edward R Stone of Wichita KS., USA, built the B-2 type of aircraft. It is known that it was registered N568Y and powered by a Packard diesel engine.
Stone Hybrid
The ‘Hybrid’ was completed by C.B. Stone in 1936. The fuselage is part of a Heath Parasol built about three years prior. The landing gear and centre section were designed by Stone, and the radiator was from one bank of a Hisso engine.

Stolz Torpedo-Flugzeug
Franz Stolz built his design in 1909 in the German town Rastatt. Due to its form it was named the ‘Torpedo-Flugmaschine’ [Torpedo Flying machine]. To fund (further) construction the design of Stolz was exhibited against payment in the Carl Franz Halle, but this financial help was not enough. Stolz had to auction his machine in December 1909 and the machine never did fly.
Stolp SA-900 V-Star
Designed by Lou Stolp as a low-cost, low-horsepower, fun machine, it is inexpensive, easy to build, and very easy to fly. Basically a biplane version of the parasol-winged Starlet. First flown in 1981, the light wing loading insures a slow landing speed and short takeoff. Stability is excellent and ample control surfaces give rapid response to light control pressures.
The structure is stressed to withstand both plus and minus 9 G’s, and horsepower may vary from 60 to 125. With the 65 HP Continental, the rate of climb is about 600 fpm, cruise speed is 75 mph, stall speed is 35 mph. This aircraft also flies well with a Rotax, Subaru, Suzuki, or Lycoming engine.
The fuselage is constructed of welded steel tubing, and the wings have spruce spars and plywood ribs with 1/4″ cap strips. Raw material kits as well as kits with the tubing cut to length and scribed for fitting are available. Wing Kits may be bought with finished spars, spar plates, ribs cut out, and fittings cut to size.

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.

Stolp SA-700 Acroduster 1
First introduced in 1973, the SA-700 Acroduster is a single-seat, fully aerobatic biplane suitable for engines in the 125-200 hp range. Its fuselage is an all-metal structure constructed from light alloy, and its wings are conventional two-spar structures with spruce spars, plywood ribs and fabric covering. A unique feature of the Acroduster 1 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.
The Acroduster uses com¬pletely separate wing panels pinned in the center with a pivot type joint and tied to the fuselage with an open stance ca¬bane that has four mounting points on the wings.
They are always building from a kit because Osborne won’t sell a set of plans without the com¬plete materials kit to keep them compa¬ny. The kit is literally a complete, but disassembled, airplane that needs only the engine and propeller. Even the motor mount and gas tank are completely fin¬ished and ready to nail in place.

Stolp SA-500 Starlet
First flown in 1968, the Starlet is a single-place parasol-winged monoplane. This ship was originally designed by Lou Stolp to handle a Volkswagen engine but now has been modified to house small air¬craft engines. Engines most commonly used are the VW 1500 or the 108-hp Lycoming.
Construction follows standard Stolp Starduster practice. All basic structure except the wing is made of 4130 steel tubing. The wing uses spruce spars and plywood ribs with cap strips. The airfoil is a Clark Y, High-Lift.
Optimum engine is the 108 HP Lycoming; however, engines of 85 HP to 125 HP may be used. The Starlet will fly well with Rotax, Subaru, Suzuki, or Continental engines.
The drawings are quite complete and easy to follow, with ribs printed to full size. The drawings are printed on an offset press so they will not fade and shrinking is held to a minimum.
All material kits are available from Stolp Starduster Corporation at reasonable prices. In addition, we can furnish fabricated wings ready to cover, complete welded assembly, turtlebacks, nose cowls, wheel pants, windshields, aluminum fuel tanks, etc.
The Starlet SA500 is easy and economical to build and fun to fly. It is stable and relatively fast. The parasol wing makes it especially suitable for operating out of rough field. Although a small airplane, the Starlet has a roomy cockpit suitable for a large adult.
Kits and plans were marketed for home-builders for $35.00.

Stolp SA-300 Starduster 2
Designed by Lou Stolp and first flown in 1971, the Starduster Too was built to fill a need for a reasonably sized, two-place, open sport biplane. It was built to fly just for fun and is not intended to be an aerobatic airplane. It is quite strong, however, and many owners use the aircraft for aerobatic flight, but this is beyond the original concept of the machine. The aircraft is rated +/- 6G. Stability is good and the light wing loading makes slow landing speed and short-field operation outstanding.
Stolp SA-300 Starduster 2 Article
The main structure of the airplane is built of 4130 steel tubing, wood faired and fabric covered, and sheet stock and has no machined fittings or other complicated bends, which is an advantage for the average homebuilder with limited machine equipment to use. The wings have spruce spars and the ribs are made of 1/4″ plywood using a modified M-6 airfoil and fabric cover. All four wings carry ailerons. Construction of the plane has been kept as simple as possible.
The prints are quite complete with ribs and most fittings full size, which saves considerable time on construction of these parts.
The O-360 Lycoming is the best optimum size engine either in the 180 HP or the 200 HP version. Quite a few Starduster Too aircraft have been constructed with the Lycoming IO-540, with as much as 375 HP. There are Ranger powered, Ford V-8 and V-6 powered, Continental powered, Jacobs, and even some R-985 powered examples. The airframe is a proven unit and allows for many different types and kinds of engines. On the low end of the power curve there are some 125 HP aircraft in service. Stolp recommends the 180-hp Lycoming with a constant-speed prop as the Optimum powerplant. There are several aircraft with over 2,500 flying hours, and one with more than 5,000 hours.
All raw materials as well as certain prefabricated parts (such as fiberglass turtlebacks, nose cowls, wheel pants, cockpit cowlings, welded aluminum fuel tanks, plexiglass windshields, canopies, and so forth) are available at reasonable prices.
