Ya know, thats cool when you can go out and just snap a video to prove a point. LOL. But...... i hate to tell ya.......In the videos its driving through the maneuver. A snap is when the wing stalls and i gotta tell ya the wing is not stalled in the video. Your plane is about 2 feet over from where you started. On snaps your fuse stays on the same line. Or close to it. Try it without elevator. It will look more like a snap. Or give some elevator to start and then get out of it. I guess it all depends on how you look at it.
Technically...no its not a snap. General flying ya its a snap.
to me it not. SORRY.
