Hi I just bought a FC40 and was hoping to take a first flight today but going through the start up sequence noticed that the transmitter was set to FCC standard (two beeps on power up). Not sure why it was set like that considering I bought it in the UK. Anyway, I read the manual which stated that I could change it by turning the potentiometer on the back counter clock wise. When I attempted this the screw just spins and never reaches a limit, and when I power up I still get the two beeps saying it's in FCC mode. Any ideas how I can get it into CE mode? Am I doing something wrong?
