when radio is cut on the mast goes up, but when fully extended the motor continues to run and there is a loud clicking sound. this will stop after a while. Have tried to impress on kids and wife to stop running it up until we fix, but ugh.... if the antenna is up when cut car off it stays up. as soons as cut the car on with the antenna up, it does the clicking thing also. based on reading on here I am not sure that it is the mast, is their a sensor that needs resetting or replacing?
