RuSky Group, a new team of developers, have announced the development of a Yak-52 for X-Plane 11. Having first flown in 1979, the Yakovlev Yak-52 is a Soviet trainer aircraft that first flew in 1979, and was piloted by pilots of the USSR, Russia and other countries.
The team state they are aiming to create a high-fidelity simulation of the aircraft, with an emphasis on the systems, engine and aerodynamics of the aircraft. Additionally, they claim the RPM (RO-2) regulator has already been modelled, and airfoils will be fine-tuned for realistic aerobatic characteristics.
The two above images are renders from a 3D modelling software. The remainder are screenshots of the aircraft in the simulator.
The team gave a status list of what is reportedly in progress, as well as a list of features with work yet to start on.
The announcement can be found at the x-plane.org forum.
