I always carry a Large Pillar and some Ceilings on my Argy. If I see any big dinos worth taming I place the pillar and the ceilings on it, land on it and just tranq safely from there. Just make sure your flyer doesn't go flying in front of the dino. Also, as usual, get ready to run after the dino before the last shot. So probably better to clear out the area first if you can.
