I think that my problem is I am under the "P. Mix" I think that I should be under the "W. Mix" in the computer because that is where I set up for the plane to have flapersons.....maybe someone that has the same radio that I have and they could help........well, i'll try what you said one more time......I just read about the P. Mix and it said "press the select........use the data input lever to set the percentage of mixing from -100% to +100%.......ok......THANKS.......
