Quadcopter Help Please
 

I currently built my F330 Quadcopter with the KK2.1.5 board.

When i do a receiver test everything seems to work fine. It flies nice and smooth but the when turning the throttle stick left and right (Yaw) when flying it doesn't seem to rotate the quad.

I'm using the Turnigy 9XR Transmitter and Orange Receiver and Module.

Please send me your answers as to what my problem could be. :)

*NOTE* I have now fixed the quadcopter and the Yaw is working like a treat!

What did you find out? Others will be glad to have the answer too.
