As a first entry at simMarket, the Yak-50 recently launched by A1R Design Bureau has a quite impressive features list, and obviously neat commercial screenshots too.

Their aerobatic aircraft model comes with electric and pneumatic systems fully simulated, realistic startup procedure. That should raise the interest of simmers in need of technically advanced addons. And for those who look for beautiful and accurate models, note that it features all the possible visual effects on the textures, and the virtual cockpit uses 3D gauges.
