Hi all
i could remember when this tx arrived to me i was quite disappointed to see that ch5 and ch6 2 and 3 position switches 
today i opened it and replaced thos ch5 and ch6 with variables .
1.remove tx batt. Open the tx 4screws on back and gently remove back.
2. There u can see 2 small rectangular pcb namely g3 a and g3b 
3. Desolder the swith and replace with a 1k ohm potentiometer
4. Repack it
sorry i am a electronics guy so i dont know how to apply the settings of othe variables on these aux channels.
I also did a mod to add 2 more channels to the tx but i only have rz6 so i dont recieve those 7th and 8th channel . But stay tuned i will soon fing out .
Thanks
