Developer Alex Pepelatz has announced the development of a Yakovlev Yak-18T for X-Plane 12 here on the X-Plane.org forum. Following his Yak-55M, this marks the next Russian classic from his portfolio. The Yak-18 is a radial-engine-powered training aircraft from the former Soviet Union. The Yak-18T is a cabin-modified version of the base model to feature a four seater cabin.

 

The first preview screenshots so far only show the bare, untextured 3D model. However, it looks extremely detailed.
