Randy Schlitter began building “sailtrikes” (better known to us as land yachts) in 1974 in Kansas before moving on to pushbikes and microlights. His first flying machine was the Coyote, which first flew in March of 1983 under the Aeromax name. This was soon changed to the RANS name. RANS standing for Research and Natural Systems.

Ranger V-770

TerryLeave a comment

The Ranger V-770 was an American air-cooled inverted Vee aero-engine developed by the Ranger Aircraft Engine Division of the Fairchild Engine & Aircraft Corporation and first run in 1931.

In 1931, the V-770 design was put to paper, based on the Ranger 6-440 series of inline air-cooled engines, and test flown in the Vought XSO2U-1 Scout. In 1938 it was tested in the Curtiss SO3C Seamew and found to be unreliable with a tendency to overheat in low-speed flight. By 1941 a more developed V-770 was installed in the Fairchild XAT-14 Gunner prototype and found satisfactory for the production Fairchild AT-21 Gunner gunnery school aircraft.

Produced from 1941 to 1945, the V-770 featured a two-piece aluminum alloy crankcase, steel barreled cylinders with integral aluminum alloy fins and aluminum alloy heads. The V-770 was one of very few V-type, in-line, air-cooled engines to reach production. The engine was used in a relatively small number of Army Air Forces aircraft, among them the Fairchild AT-21 twin-engine trainer of which approximately 175 were built, and in the two Bell XP-77s.

By 1944, the unit cost was US$11,000

The Rankin RBM-4 of 1928 was a two-place low wing monoplane powered by a 60hp LeBlond 5D engine. Fist flown by Basil B Smith, they were priced at $2,500.

One appears in a 1936 register as four-place cabin with a 200hp Wright NC9622 (how the NC was acquired is unknown)] c/n 3, owned by brothers Alexander, Arch, and Charles Rankin of Wayne MI. Company promotion also told of a three-place open cockpit with 90hp LeBlond 7D also in progress, with a useful load circa 500 lb and max speed of 110mph, as well as an ambitious plan for a network of national distributors.

Engine: 60hp LeBlond 5D
Wingspan: 37’1″
Length: 25’6″
Useful load: c.350 lb
Speed: 100 mph
