Stunt Glider Trophy

[Buckwheat]

There aren't really any guides from what I can see, so I thought I'd let everyone know how exactly to achieve this trophy.  You'll need to unlock Glide Dodge in the progression tree by completing the dragonfly side mission.  Once unlocked, you can press L1 or R1 while gliding close to an obstacle.  You'll know if you've done this correctly because the sugar glider will complete a barrel roll animation.  You can probably achieve the trophy naturally while grinding out other trophies, but I replayed the dragonfly side mission repeatedly until I had completed this trophy requirement.  It took maybe 5-10 minutes.

I did this easily by just flying at any tree from ground level and then glide dodging, you don't need to complete any mission. Just fly a couple feet near a tree then glide roll 20 times.
