I'm trying to get my DX6i configured with dual ailerons on an AR6200 rx. The right aileron deflects in the correct direction when I move the stick left or right. But the left aileron moves in the same direction as the right aileron. That is when the right aileron deflects upwards, so does the left aileron

I have it setup as follows:

Transmitter setup with Wingtail as DUALAIL
Right aileron plugged into the AIL port on RX
Left aileron plugged into AUX port on RX

I also have the transmitter setup to reverse the servo throw on the Aileron channel so that the deflection of the right aileron moves in the correct direction. It's almost like I need to reverse the AUX channel, but I don't see a reversing option for AUX in the DX6i.

Can someone help? I looked through the manual and only saw information on how to setup it up, which is what I posted above in the "setup"

Try reversing channel aux 1 flap channel.

Thanks. I didn't see AUX1 in the reversing menu. But I do see FLAP. That fixed it.
