Hi there, I'm considering ordering a plane for use with Arduplane for my lab.  I was hoping some of you could suggest good planes for my lab's purposes.

The plane will be carrying about approx. 300g of payload, including the camera, gimble, and of course APM2 and RC receiver.  It needs to fly in a waypoint grid over a forest snapping pictures, going a minimum of 5 m/s.  The point of the flight is to blanket photograph the forest for ecology purposes.  The longer the plane can fly for, the better.  Basically, it has to outperform our hexacopters that can fly 5m/s over the forest for 15 minutes. 

Thank you all for any help or advice you have!
