Tail Servo Problems

[Brutus]

Just installed HS65MG servo for rudder but its not working....powered up and servo bleeds to the tail and stays there..spool up and just goes in circles.....what the heck did i do wrong this time?:arggg:

Dont have that servo, you mean FAST circles like its chasing its own tail? reverse the switch on the gyro itself :confused:

Use subtrim to stop servo creep.

Better yet, watch the Finless Video on Align/Telebee Piezo Gyro's.
Works the same as the G110.

yes chasing tail!
got the creep to stop until i spool up and input rudder then chase the tail....................

Sounds like the gyro is operating in the wrong direction, reverse it.

yep had to reverse gyro then reverse rudder servo which doesn't make sense to me but seems to be working properly....have to run full test flight tomorrow but hovered just fine.....thanks

E-Flites servos are reversed from most hitec ones.

Reversing the rudder in the TX reverses the way the servo moves when you move the stick, reversing the switch on the gyro reverses the input the gyro gives to the servo to try and hold or bring the tail back to where it should be.

So if you install a servo reversed to the original (which just about every servo is reverse to the eflite ones) then you need to reverse both switches. It is basically two totally seperate devices operating the servo, one being the TX and the other being the gyro.
