The Moskalyev SAM-6 was an experimental design intended to test the suitability of monowheel undercarriages, lighter than conventional gear, on tailless aircraft.

The wooden SAM-6 had a conventional tail on its short fuselage but its low wing had, in addition, Scheibe-type, oval wingtip fins and rudders.

[1] It was powered by a 65 hp (48 kW), three cylinder M-23 radial engine mounted in the pointed nose of its deep fuselage and had a single seat, open cockpit.

The trials were reasonably successful and the main ski was replaced by a wheel in a trouser fairing.

No reports from tests with this landing gear are known but by late 1934 the SAM-6 had been modified into the more conventional SAM-6bis, which had two fixed, trousered mainwheels.
