H520 vs "3DR H520-G"

Hey everyone,

I am looking for someone that can help me with the drone I have. It is 3DR's version of the H520, and is named the "H520-G". (https://3dr.com/products/h520g/) I purchased this for $6,500 and unfortunately did not understand that I needed to purchase the $6,000 flight app from 3DR called "SiteScan" in order to operate this drone :-( This means I have a $6.5 k drone that I can't fly (except with manual controls, no flight telemetry data, location, or camera use).

Please help! I was hopeful that I could make connect it to Q Ground Control, but I can't get it linked up. Does ANYONE have any ideas? 3DR just said I had to purchase Site Scan...no other ideas.

Thank you, in advance, to anyone that is willing to offer ideas!

Ben
