Just Flight has today posted via their Facebook page a set of previews showcasing the currently developed Diamond DV20 for Prepar3D v4. The aircraft is developed in cooperation with Propair Flight.
The DV20 is an all-composite, T-Tail GA light aircraft. Featuring advanced avionics but for a low cost, the DV20 has been a popular trainer aircraft since it’s introduction in 1994.
The pictures that can be seen below are just renders, not screenshots from the sim. Based on the In Development section of Just Flight website, the aircraft should be coming soon, but based on the Facebook post, the aircraft is still some way off yet.
