Quetzalcoatlus stood as tall as a giraffe, , had a 37-40 foot wingspan and weighed about 500-550 pounds. It was the largest known flying animal. Being that tall, it could look giant theropods in the eye, and combined with enormous wings, it could make itself look much larger than
it actually was. This is a defensive tactic that we see in nature all the time, from the blowfish that sucks in a lot of water to make itself balloon up, to a frilled lizard showing out its frills. Making yourself look much larger than normal can save you from predation. 
Megasquids are roughly the same weight as a T Rex (8 tons), but their brains are smaller than that of a T rex. They are amazingly stupid. Thus, they could easily fall for this ruse. A good thing too, consider that, with its super long neck and super long beak, Quetzalcoatlus
could peck it like crazy. Indeed, it could strike its vocal sacks, which are on its forehead (and bloat like a frog's throat when it makes calls). To have this punctured by an oversized beak could be disastrous for a megasquid. However, the megasquid's two arms are each powerful
enough to swat small trees aside like they are nothing, and, not having bones, can stretch considerably. Perhaps the greater range that a quetzalcoatlus' neck and beak In a face to face encounter might not be enough to keep out of range of the megasquid's grasp. Still, with
its wingspan and already considerable size, Quetzalcoatlus would most likely scare a megasquid off.
Now, if it lands on a megasquid and starts pecking...well, the brain of a megasquids is located close to its eyes and is not very large. Thus, a Quetzalcoatlus will have to peck
Now, if it lands on a megasquid and starts pecking...well, the brain of a megasquids is located close to its eyes and is not very large. Thus, a Quetzalcoatlus will have to peck
through tons of flesh to get to it if it lands on top of its head. Meanwhile, a megasquid can always reach up with its arms and tear it apart.
Nevertheless, this battle will most likely take place in a face to face encounter on the ground. Unless the megasquid was near its nest

I don't see a Quetzalcoatlus landing on its head and pecking away. It also wont try a dive bomb attack (It would probably become a quadriplegic if it tried to dive bomb its beak into 8 tons of flesh). This will be a face to face encounter, and in the end. it wont take much to
fool a megasquid into believing that the Quetzalcoatlus is much larger than it actually is.
Thus, I conclude...

QUETZALCOATLUS PSYCHS MEGASQUID OUT!!!!!!!
