The E-1 was not the only domestic electron aircraft. At GAZ No. 1, at the same time as the aircraft, a glider was built from the same magnesium alloy. On its first flight, its tail broke off during landing. The remains of the airframe, which had no protective coating, abandoned in the yard, were destroyed by corrosion in less than a year.
MAI graduate M.L. Babad, with the participation of Gimmelfarb, built Airplane E-2 "Klim Voroshilov". Unlike the E-1, which had a fabric-covered wing and tail, the E-2 was entirely made of electron, even the propeller was riveted from two 10-mm sheets of magnesium alloy. According to the design, the aircraft was a cantilever monoplane with a mid-mounted rectangular wing with rounded tips. Blackburn-Tomtit engine 18 hp. soon replaced by "Anzani" with 27 hp. But the all-metal plane turned out to be too heavy for this engine.
A.I. Zhukov performed only one flight on it in 1934, which showed that the engine power was insufficient. The E-2 was not allowed to fly again due to suspicions of structural corrosion. Despite this, during the November holidays of 1935, this aircraft was demonstrated on Mayakovsky Square in Moscow as an achievement of Soviet aircraft manufacturing.
