Walkera Runner 250 Advance /w Devo 10 all but GPS

Hi all,

Yesterday I managed to get a working config for my Devo 10 with the Walkera Runner 250 (R) / Advance.

The quad flies nicely plus I can activate the video / photo.

But... I can't get the GPS (hold / RTH) to work. I was told to set it up on channel 5 / GEAR using MIX0/1/2. I've set a complex mixer giving -100, 0 or 100. Does anybody know what's not right here?

Kind regards,
Steven
