Motors spinning out of sync

[droneboy43]

I am building a quadcopter and just finished it today. I set it up in Betaflight, and went out to test it. However, the motors spin out of sync, to point that the quad flips repeatedly until I un-arm it. What is going on? Here is a list of parts I am using:

Transmitter: Frsky Taranis X9D

Receiver: Frsky X8R

ESC: https://www.banggood.com/Racerstar-...hot-for-FPV-Racer-p-1068210.html?rmmds=search

Motors: https://www.banggood.com/4X-Racerst...50-260-Multirotor-p-1066837.html?rmmds=search

Flight Controller: https://www.banggood.com/Upgrade-NA...Multirotor-Racing-p-1010232.html?rmmds=search

Have you calibrated the esc's yet? did you go thru normal set up and set center points and end points for the receiver?

Watch this and make sure you have done all the proper set up and have not overlooked anything.
