This is a good mount to overpower your tribe. You are able to hover above gigas and shoot tranx without it touching you. You can build turrets and a whole base on the quetz. Go to the red obelisk to get one. This Dino will make you OP!!!
The fun way is to jump off and grapple to your argie and whistle it to attack and since argies are slow it won’t catch up in time so tranq till it goes out also bring parachutes and consider liking so more people will know
If you manage to knock a quetzal out, try starve taming. If you never tried starve taming it’s just leaving a Dino’s hunger go to half way or lower and then you start feeding. I’ve done this many times and it’s very useful taming trick.
