Lee, I just came across your question, soory it has not been more timely. The short answer is that the only real must have for drone2map is a system that produces nadir or low oblique images (camera pointed down) and a way to record the 3D GPS coordinates of the location of the images. Along these lines the 3DR Solo and Phantom 3 work well.
Generally, the essential characteristics for best integration are:
+ Camera or Platform collection of the 3D GPS location of the images
+The ability to record nadir or near nadir imagery
+A camera model supported in Drone2Map specifically or by default.
+A passable quality sensor
In addition, helpful characteristics are:
+ Efficient way to download the images
+ High image resolution
+ Auto triggered Sensor
+ The ability fly generated way points
+ A mission planning system to generate waypoints with proper overlap
