I'm also an owner of a H520e since December 2020 and you are so correct. Customer service is almost nonexistent with Yuneec and their website I had to going through the website designers to get them to respond to my emails. I have emailed customer service many times about the OFDM firmware not uploading and micro sd card problems and their lightly written manual doesn't cover a fiction of what you need to know about this bird. I wish you the best of luck as well take care!I am an owner of a h520e rtk for a few days but I did not think that there was such a great abandonment of its customers by yuneec, lu will lose all between dji and autel. Is it possible that there is no in-depth manual on rtk and ppk? I found a converter in the sdcard because, is there any procedure to make the files compatible? bohhhhhh assistance is non-existent !!! Rtk is ok but how do i see the accuracy in real time???
The re is someone that can help me to understand something about this h520e??thankss
