), 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.
300 Hz max for the 9257, so set the gyro for 1520/250.
If your tail was wagging, that suggests to me that the tail servo was still working, otherwise the heli would have just spun counterclockwise at high speed. What's your gain set to on your radio? It should probably be in the 25% - 30% range on a 9x
Edit: it's been a long day...30% to 45% is a reasonable number on the 9x gyro menu, not 25 to 30
