I’m pretty frustrated too at this **** junk! Never again I lay my money on Yuneec. I throw it in a dumpster soon. I prefere things that works properly without any problems!???
Have you contacted Yuneec Customer Support yet? We are pilots just as you are and have as much insight to what was done in the update as you do. Until someone gets off their duff and gets in touch with Customer Support, all of you will just be having a poo fight.
I don’t have a Mantis Q so I can’t contact them myself.
