Disclaimer: This is based on Nef680's work. They did an excellent job on it and I couldn't have made this without the base model that they created. You should check out their version also. This has always been a favorite plane of mine ever since I first saw it. I fully enjoyed Nef680's work on this and just wanted to do some updating. The base plane and flaps are Nef680's work. The landing gear are modified versions of Nef680's work.

This has working navigation and cockpit lights as well as a light in the bombardiers station. The control yoke moves as it should in flight, the forward green lever in the cockpit is for the flaps, the red handled lever next to it is for bomb bay doors. The two levers below them are for throttle, and the red handled lever at the back of the instrument cluster is for landing gear. The wheel is for trim. The bomb bay doors and turrets are fully functional.

There are 4 cameras.
Camera 1: jumpseat in cockpit
Camera 2: pilots seat in cockpit
Camera 3: bombardiers position
Camera 4: rear gunners position

AG1: Top Turret Rotation
AG2: Top Turret Elevation
AG3: Flaps
AG4: Bomb Bay Doors
AG5: Bottom Turret Rotations
AG6: Bottom Turret Elevation
AG7 Turret Guns
AG8: Navigation and Interior Lights
All AGs are controlled by VTOL except the lights. The landing lights retract and turn off when you raise the gear.
