If taming with a two man tapajera team, make sure your tapajera has LOTS of stamina. You will have to speed to follow the quetz around. Make sure to have a good point man too, they will fly through forests and be next to impossible to see without a good eye. And always make sure to bring extra supplies!
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
In order to solo tame a quetz, you could use an argentavis and a pulmiscorpius. Just pick up the pulmiscorpius, and do whistle attack target while looking at the quetz, your pulmiscorpius should start attacking the quetz, raising it's torpidity until it is knocked out.
