Can someone please confirm that the CH6 tuning method is working with MP v1.2.4, method outlined below (from the wiki - http://code.google.com/p/arducopter/wiki/AC2_Tweaks):

Select the "ArduCopter Configuration" tab in the Mission Planner, choose the CH6 option you'd like to tune. e.g. CH6_RATE_KP.

From MP v1.1.44+ these high and low values can be adjusted in boxes just below the CH6 options. Alternatively you can also adjust TUNE_HIGH and TUNE_LOW in the left hand pane.

Input the high and low limit of the parameter you'd like to tune, choose a value of + and - around 30-40% of default, (so for CH6_RATE_KP set 'low' to 0.100 and 'high' to 0.180 from the default of 0.140)

Then click 'Write Params'. To check the values click 'Refresh Params', your high and low values should be correct in both the Parameter List tab (under TUNE_HIGH & TUNE_LOW) and in the adjustment boxes. If not enter them again.

To test that the values are changing: move the lever or knob then click 'Refresh Params', the value should be displayed in the center pane in the respective box, move it again and click 'Refresh Params' again, the value should've changed. Alternatively select the Terminal tab, type 'test' and then 'tune' and your value will scroll down in the window, adjust the knob or lever to see the values change.

Now set your CH6 knob or lever to between 0 and 25% on your transmitter, then carefully test fly, land and tune the parameter with the knob or lever, test fly again.

To read your final parameter, leave the knob or lever on your Tx in your chosen position, connect to the MP then click 'Refresh Params', the value should be displayed in the in the respective box in the Parameter List tab (under TUNE_HIGH & TUNE_LOW). Alternatively select the Terminal tab again, type 'test' and then 'tune' and your value will scroll down in the window. Enter this value into the correct position in the Configuration tab. Tune another parameter or, if you're finished, set the parameter to CH6_NONE (important!)

All I get is the upper and lower value but nothing in between...?
