Rudder/Yaw values stay active even when stick springs to center position

Posted by Robert Beatty on October 12, 2010 at 8:52pm

Please forgive what is probably a very novice question regarding the configurator, RC aircraft, and the Arudcopter. 

I've attached my Arducopter to the configurator to re-confirm my sensors, calibration, etc.
I've completed the Arducopter wiki Pre-Flight Test and everything is working well. My question is this:

When I move my rudder/yaw stick left or right, the motor controls shown in the configurator respond appropriately, but when I let go of the stick it springs back to the center position and the motors stay at the earlier position. In other words, they maintain the yaw. It seems to me that would cause my Arducopter to continue to yaw even after I've let go of the stick (and it's sprung back to the center position). In order to stop the yaw, I need to push the stick to the opposite side and make little adjustments until I get the motors re-centered again.

Is this normal and desirable behavior for RC? If so, I'll learn to fly it that way. Or is this something I should change? If so, how?

Reference Info: I am using a T10CHG Futaba Transmitter in basic H-1 Helicopter mode. The yaw/rudder stick is on the left and springs back to the center (unlike the Throttle, which stays where you put it).

    Like John said, earlier you gave "command" to your quad to rotate left or right. Returning yaw stick to center does not return your quad on original heading. It still tries to rotate as you asked it to do earlier. IF you then physically rotate your quad to direction where you commanded it by stick move, you should see that motor levels are getting even:ish.

    So with rudder stick you command your quad to rotate it's "nose" heading either to turn to left or right.. Not absolute direction. Just like in airplanes, if you give rudder, it start to turn and when you release rudder it will continue new selected heading.

    You can expect the motors to keep trying to yaw the quad if it hasn't responded to your input. If you input right rudder while the quad is on the bench the motor commands will indicate that it's trying to yaw the quad. if you then manually rotate the quad to the right you should see the motor commands level out again.

    I don't understand the question, I'm afraid. In flight, the ArduCopter only yaws when the stick is pushed to one side or another. When it returns to the center, the quad stops rotating.
