Vertibird v3 addon

Here is my third version of the Vertibird I have been creating. It's Easier to control while still being quite a challenge. Incredibly fun to fly around in and lightning fast too. I have optimised the design as a whole an now it can be run at 100% game speed with no lag. I have also reduced the size so it can now run in the mission bounding box so you can now complete missions with it. Controls: Up: Rotate propellers forward Down: Rotate propellers backward Left: Turn left Right: Turn right T: Increase propeller speed G: Reduce propeller speed F: Fire cannons R: Bombs Y: Bombs
