    Goal: to assign switch #2 to altitude hold on/off

    We've gone through the steps in the Graupner manual and the MK Graupner supplement to assign the switch to channel 9. It shows up in the Graupner display as assigned to that channel.

    Kopter Tools shows the various setting accurately; it shows the gas, nick, roll, and yaw sticks working properly. It also shows the three-position switch assigned to the channels for GPS, Attitude, PH, and CH operating properly.

    Kopter Tools shows channel 9 assigned to altitude hold.

    It shows switch #2 assigned to channel 9, but operation of the switch shows no effect in Kopter Tools. The value on channel 9 remains at 33, regardless of switch position.

    We've repeated the process multiple times, with the same result. Each time, we write the settings to the vehicle and get the beeps showing that it was written successfully.

    We've also tried assigning other switches to channel 9, with the same result.

    Any ideas about what we're doing wrong? Suggestions?

    Hank: Could you use MK Tool to Save the settings to a .mkp file and post that file just so we can double check the settings.
    Can you also confirm how you have the SUMO setting on the MX20 please?
