The V3 was rushed. I forgot to add parachutes and trim for elevators. Also i added an extra airbrake in the back. just to be cool.

AG 1 for parachutes (The only thing that can stop the plane on touchdown when you're below 300 mph)

Original V3 Here

Also, the reason It's not a successor of the V3 on the auto credit, it's because when i uploaded the V2, i made a V2.1 but don't want to call it V2.1. So, i deleted the original V2 and upload the V2.1, calling it V2. But by doing it, it's no longer crediting the first version, instead, it credits the original second version which is gone. And when made new version based of V2/V2.1 of this plane, it no longer credits the V2,V2.1, nor the version made after it.
