I shared Vulkan model 1, which has an identical diameters of 2 and 3 stages (simplified variant). Now I prepare for sharing the model 2, which answers the project of authors in a greater degree (different diameters of 2 and 3 stages). Anatoli Metzger heroically helps me in this work (test building). I show his pictures in a gallery. Also after testing I going to show modernized LEK with the folded legs, which can it will be set under the fairing of Vulkan.
