ED wanted to release the F4U first and didn't want the La-7 taking sales from it, or OG is still polishing it. Those are the only reasons I can think of why we don't have the Lavochkin yet
Day one buy for me as well. The La-5FN and La-7 are favorite warbirds and I've been eagerly waiting for the 7 to get added to IL2, OctopusG beat them to the punch. Beyond stoked for this plane.
