This plane bears an uncanny resemblance to the Lagg-3. Is there any connection between the two? Beautiful model too!

Yeah as almost when look at picture as D.520 have much narrow and sexy. That's explain why most of used use Lagg-3 series 3 as D.520 in create missions all time. I just took a look at their Specifications and found out their size and weight almost same as slight more power engine and weapon on Lagg-3
