This is a faithful reproduction of the BAT 21 O2 Skymaster with as much detail as could be squeezed into it to the point of crashing systems due to memory usage. All Flight control surfaces, and propellers can be moved, angled, spun, except the undercart, that can be in the scene, or hidden from render, retracting this unique undercarriage set-up was a bit too much to get right, and presented further complications. Though this Model renders Just Beautifully as it is. Cockpit, Instruments, Seats, and interior panels, make scene placement look very compelling. Just Add PILOT :)
