The Heli-Russia 2019 show daily reported on a new ultra-light co-axial helicopter built in Kumertau by the Moscow based firm of Aeroelecktromash , developed by with assistance from OKB Rotor and designated the R-34. Apparently it had started flight testing in 2019 and development envisaged included a fully electric version as well as an unmanned variant.

According to Aeroelectromach "The R-34 has been built to a patented design of a coaxial helicopter and is the most compact, efficient, and low-noise aircraft in its class. The helicopter is equipped with a 130 hp gasoline engine Rotax 915. The AC design features hingeless suspension of blades, a composite torsion, and a parachute rescue system."

Also on display at HeliRussia 2019, “Aeroelektromach for the first time presented a full-scale prototype of electric motor ВД-25000 designed for driving aircraft airscrews. The motor is based on the converter-fed motor with permanent magnets. Its rated power is to be equal to 25 kW (34 hp), with nominal rotation speed making approximately 2500 rpm ".
