These guy are very useful for taming quetzals. But make sure you stay under it. The drivers hit box can get caught in the bow,crossbow,longneck and knock you out. After that your body will fall halfway down to the ground and you will then wake up and die. You should only pump stam,weight and movement.
This Dino is my favorite on the island for various reasons. First, it can hold 2 passengers, a pilot, and carry another. Second, it is the most maneuverable flyer out there. It can fly sideways, backwards, and can land on vertical surfaces (cliffs, redwoods.) Third, it has a tek saddle, so you can have four dubs on that thing (tek saddle, 2 passengers, and one carried person.)
you don’t need to upgrade it’s stamina, if you are in the air and it’s stamina is low, just get in the back seat and wait for it’s stamina to recover, no need to land, if you don’t whistle it to follow, it will land automatically. I hope this helps :)
