I have been running my GA250 gyro with my Emax ES 9257 servo for a while on my hk450 and its been amazing until this afternoon. I went out for a fly at midday and it went without a hitch, did a flip, some circuits ect, i then went out to fly again this arvo and as soon as i put the heli in the air massive tail wag and no response from the tail servo when i give an input, at first i thought i had changed the tail servo frequencey, i tried every single one without success. i then i checked my settings on my remote (turnigy 9x
), no problems there i could see. So could someone please help me with this issue or at the very least give me the frequency for the tail servo so i have a base to sought out the servos from.
