Verzilov Staliniets-2bis
 
A development of the “Staliniets-2” built in 1935, the “Staliniets-2bis” (Russian: Верзилов “Сталинец-2бис”) glider was designed as a towed two-seater.
 
Structurally it was designed as a monoplane with a high wing in parasol, braced by uprights. The wing featured an R-II profile with a single spar structure and was built in two independent sections, which were fixed to the upper fuselage structure, featuring an upright on each side to ensure the necessary structural rigidity. The entire wing was covered by 1.5 - 2 mm thick plywood sheets and had a total weight of 158 kg.
 
The fuselage featured oval section and plywood overlay. Eighteen frames and four main spars were included in its structure.
The vibration problems presented by the previous “Staliniets-2” made it necessary to locate the tail planes somewhat lower in the empennage. The stabilizer was attached to the keel structure at two points and a bracing post.
 
The landing gear consisted of a rigid, trunk-shaped ski, to which a trolley was attached, which could be released after take-off from the second seat.
 
The two crew members sat in tandem seats. The second position was located just above the center of gravity of the glider, so the absence of its occupant did not bring problems of variation of the centering.
 
As a result of the modifications made, the new glider was 25 kg heavier than its predecessor.
 
For the XI National Competition gliding in Koktebel between 6 September and 6 October of 1935 both "Staliniets- 2" and the "Staliniets-4" were valued by the technical commission, receiving approval for the flights without objections.
 
During the XI National Sailing Competitions on the “Staliniets-2bis”, test pilot Valentin V. Licitsyn with passenger B. Dolya set a new world record for flight duration for a two-seater glider by staying in the air between 2 and October 3 for 38 hours and 40 minutes. Again the record was recognized only as a national one, because the USSR in those years was not a member of the FAI.
