I have a Falcon 250 pro quad: https://www.fasttech.com/product/615...r-c-quadcopter
which I recently crashed and had to replace an ESC and motor
ESC: US$8.99 VGOOD 20A 2-4S 32-Bit Brushless ESC With 4A SBEC for Fixed Wing RC Airplane RC Parts from Toys Hobbies and Robot on banggood.com
Motor: US$31.37 4X Racerstar Racing Edition 2204 BR2204 2300KV 2-3S Brushless Motor CW/CCW For 250 260 280 RC Drone FPV Racing RC Parts from Toys Hobbies and Robot on banggood.com

I have replaced all of the motors and ECSs, the board is oriented correctly in Librepilot and the motors are spinning in the correct order/direction with the correct props attached.

I have calibrated the ESCs and also gone through setup in Librepilot however the motors very quickly de-sync and the quad flips. If I power up the throttle to 5% the motors will slowly start building up throttle themselves before the quad eventually flips by itself with the stick at 5% he entire time.

Does anyone have any ideas as I am starting to lose hope with this one!
