I don't need convincing thanks, just reiterating what Kloner talked about earlier in the thread which perhaps you haven't read.Suggest you watch some YouTube videos for SuperX, many have been made by users showing the accuracy of position and maintaining station in all types of wind, needless to say many users are from the DJI camp and won't go back.
SX has a logging system called black box that records all data from the FC this can then be played back for problem solving of reliving the flight here can also be seen, to 6 decimal places the GPS coordinates of the entire flight.
Please do your research! it is not my thing to try to convince you, other than to say your comments were not related to the OP's question.
X
"the heading magnetism showed an awful lot of movement for it sitting still.... gps lock was not even close to solid in the last graph,,, it showed good on the first graphs that it crashed on."
and a further question relating to why it wouldn't be a good idea to take off in GPS.
Super X accuracy is 1m plus or minus vertical and 2m plus or minus horizontal, just read the manual, so I would say that it isn't good practice to talk off or land in GPS.
