Radiolink Minipix ESC not calibrated

I builded my quadcopter use radiolink minipix V1.0. When I connected escs minipix, it is not calibrated and I cannot armed it. I calibrated motors to connect receiver one by one but it is still same problem.
How can I fix it?

Check the way you connect the all the esc… what kind of esc do you have mount?
if you have set safety switch just press it if you want arm… just in case check all the warnings you have in MP hud…, remove props and connect your vehicle to MP with usb and battery… try arm and check the hud
