Yaw sensitivity problem

[ben995]

I'm new to multicopters and multiwii.. On MultiWiiConfig there is no apparent sensitivity/attenuation adjustment. I've tried changing the rate and expo for throttle and pitch/roll but it doesn't change the fact that even if i breathe on the yaw stick, it changes motor speed drastically as seen on the config gui. If someone could shed some light on this it'd be appreciated. I haven't been able to get off the ground yet, it's frustrating...

Try to decrease rc rate maybe or set some expo on Tx.

RC rate as set in MWII GUI has no influence on YAW (as discussed in a thread from couple of days back).
@ben995: YAW on multicopter is far less effective than on CP heli so probably you will not have any issues flying with default setup.
Also on quad to get proper YAW response MWII must decrease rpm on two motors diagonally/front-back and increase on other two to keep quad stable/level.

The way I address the YAW Sensitivity in my custom mixing is to divide axisPID[YAW] by two or what ever value is required in the Output.ino file.

Sorry my bad.

Thanks for the responses. I have it flying now even though there is considerable drift in the yaw. Pid numbers will most likely need tweaked..
