These are general tips for building RC planes/quads/whatever:

* Propellers have a direction: The top usually has letters like, for example, "6040" (which denotes the size and pitch of the propeller), and the top needs to always point towards where the plane will be flying (the front). No matter if you have a pusher or puller, the top of the propeller needs to be pointing forward.
* When it comes to cameras/standards, the difference between PAL and NTSC is that PAL has higher resolution (625 lines, ie 576i for PAL vs 525 lines, ie 480i for NTSC), but lower framerate (25 fps for PAL vs 29.97 fps for NTSC). I use PAL because I prefer having higher resolution.
* If doing manual/hand launches of planes/wings, you'll notice that you need to have your hand on the pitch/roll stick when launching, which means you need to launch with your left hand, which is where the arm and throttle controls usually are. That makes it hard to throttle up to start the launch, or down (or disarm) in an emergency.

  To make things a bit easier, I set the back right switch (SG) to override the throttle and set it to the launch throttle (40% for me, for example). That way, I can arm, keep the throttle down, and flip SG with my right hand. That will throttle up enough to easily launch the wing, and if something goes wrong I can still either disarm or flip SG down so the motor stops again.
* ESCs that run on the DShot protocol don't need throttle calibration, you can go ahead and use them right away and they'll do the right thing.
