Those Jabiru aircraft are the worst thing I've ever flown, honestly can't find one good thing about them, I've no idea why anyone buys them.
Pretty sure that's the stall warner you can hear blaring at the start of the clip, so he's probably trying to drag it into the air as early as he can, obviously without success.
The left turn doesn't look like he initiated it, perhaps that it just drifted over to the left due to the prop slipstream. Who knows, but at least it's one less Jabiru in the world and noone hurt by it.
