What are the modifications required for drone canopy leaf sampling?

• Make sure the prop blades are protected.
• Modify the tail to include a collection device.  A very sharp blade at a sharp angle allows twigs to be cut off and often to remain caught in the space between the blade and tail.
• Learn how to drive the drone using the camera.
