I have a Graupner MX-20 and GR-12.
When using the sum signal from the GR-12 receiver. the channel order is wrong. I cannot find a way to change it in the Graupner equipment so I have started looking to change it in the source for the arducopter software. Not being a "C" programmer, I am having trouble locating the proper place to make the changes. I meed to map GR-12 ch 1 to 3Throttle, GR-12 ch 2 to 1 Roll, and GR-12 ch 3 to 2 Pitch. Could you please point me in the right direction. I have tried changing it in a couple of places but it didn't change the result.
Thanks,

Yes, it is possible to reassign channel from the radio menu.
Go to page 206 of the Mx20 manual "Exchanging TX channels" or something similar as title .
Mapping is not very intuitive, anyway this is the setting in the Graupner MX20 Menu:
TXCH1 ---> out3 (Gas)
TXCH2 ---> out4 (Yaw)
TXCH3 ---> out2 (Pitch)
TCCH4 ---> out1 (Roll)
