Servo help needed

[mcl fabrication]

I know it can be done on a open source radio and my dx8 threw mixing, running one servo threw two channel. I remember doing so when mixing channels for the first time on my dx8 when trying to . don't know if all channels are mixable on the dx6 its worth a try. If I remember correctly I may be wrong but You are limited to how many channels can be mixed in a dx6. You basically want to figure out which channel will be your master channel and then set up a mix and assign it to the slave the other channel or half and half.
Half and half ( use one stick (gimbal) one of the channels to control two channel two different functions or one function),a way how to get 8 channels from 4 channels. Which may help.All this is depending upon your radio. check your manual on mixing on your dx6.
No I'm not a expert just had a few radios past threw my hands.
