I’ve just got my X220. I’ve followed the instructions in Sam’s blog post from 6 April (even the paper clip trick which I haven’t used since Windows 3.1 ) and have setup the flight modes in Betaflight from the post on 5 April. Everything on screen looks fine, but when I switch the Arm and try to lift the quad it attempts suicide! I’ve got it about 2 feet in the air using a mixture of inputs but it’s pretty much uncontrollable. Has anyone any idea what I’ve done wrong or is there a way I can wipe it and start again?
