The Os-19 “Vulture” is an amphibious multi-role utility transport that can perform various roles such as search-and-rescue, troop transport, medevac, plane guard, and mine clearing operations.
This design is intended to be “cheap” to build (i.e. using parts that often come in multiples in a set) and uses parts from the SV-51 Lance, ST-33 Trident, and AC-75 Gladius sets. The cockpit depicted comes from the FT-12 Maul set, although any two-peg cockpit can be used.
