The R3 carried two Mk108 cannons in the upper nose in place of the weak 4xMg17. Serial Production started by September 1943 although similar pre-series aircraft under the designation G-2/U9 had already been in production for a couple of month. The production of the standard G-2 armed with 4 MG17 ended entirely when the R3 production started. By Groundcrew Design Group. Requires "gc110_01.zip" (below)
