Got to ask whats the plus side of going from a plus to a 520 besides the mapping aspect ? What I'm trying to figure out is how a novice like myself would benefit from this upgrade. Mapping of the 520 doesn't seem to be a hard task to get to perform, but the outside software could be difficult in grasping. I also see that DJI seems to be a better product at mapping from a quick look into it ? I hope youse (yes a Bostonian accent) can enlighten me somewhat ?
