Those plans look like the same ones I've used to build about 10 or so different Versa Wings. If you're watching the original build video, he's using a speed build kit and I THINK the build video talks about how there's a fold that's introduced so they can get the packaging to be smaller and cheaper when sending it out. That said, it's been a while since I've watched the video, so I may be mis-remembering it.
Are you trying to build it in tractor configuration (with the motor and prop at the front), or in a pusher configuration (with the motor and prop at the rear)? I know there's a supplemental video for doing it in pusher configuration, and the plans are missing the power pod for tractor configuration...I've never built a tractor configuration Versa Wing, though, because we all fly ours in pusher configuration for our combat events - keeps it from having the streamers tangle in the motor and burn up.
