The Yakovlev EG (Eksperimentalnyi Gelikopter), also commonly known as the Yak-M11FR-1 and Sh (Shootka), was an experimental aircraft with coaxial rotors.
The rear fuselage was fabric covered and supported a tailplane-style unit with twin endplate fins, as well as a tailskid.
[1] The M-11FR engine was mounted behind the gearbox which it drove via a short shaft.
A fixed tricycle undercarriage mounted on steel tube trusses supported the helicopter on the ground.
[1] In early 1948 the M-11FR engine was replaced by a 190 hp (140 kW) M-12, which proved troublesome so an M-11FR was refitted to complete the flight trials by 8 July 1948.
