This is what i have been working with.
Its the ACCST model.
I believe I got the QX7 updated but i have tired 3 different SD cards 1 old and 2 band new ones.
the QX7 knows there is a card in but displays nothing.
I have already copied the newest SD card contents from the PC to the Card. Inserted...
I just received a Rekon FPV Rekon5. I also have the Frisky X-xsr receiver. Receiver shows all three lights. Also transmitter will not read SD card. So can not flash receiver. I'm 10 hours in and no closer to a solution.
