Hi, Your advice regarding the ESC assignment was correct and had to restart everything and then it came good, however I have fixed the
problem and pass this info on as it can easily happen to others. I took the top off again to investigate and check all wires and found the
problem it was a black wire snapped in half and happened when I pulled out the connection wires to plug in GUI and the Black wire
was shorter that the rest so it broke in have and soldered it back together and the quad is perfect binding no longer a problem so all good.
Thanks everyone for your help, appreciate it. regards, John
