As story elements in Fallout Miami called for a heavy-lift Vertibird, a new design was needed. The new Vertibird is designed to carry out tasks which require heavy-lifting as well as troop transport.
Some of the main inspiration sources for this design were insects, real-life cargo helicopters and airplanes. Since being lore friendly is an obvious requirement for any design on this project, the existing Fallout 4 Vertibird design was one of my design anchor points for this vehicle as well.
