Look at the Naza assistant and go to each unused channel in the mixer one at a time. Setting "source" to FULL and the weight to 100. You'll have to experiment with setting the "switch" to SW1, SW2, etc. Then look in the assistant and see if you can get X1/X2 to move with your chosen pot. I'd look for you but after all this, my darn DragonLink RX I used in this is having range/signal issues and I think I'll have to send it to Mike to look at. So, it's not in the quad anymore.
