DX3R mixing
 

Hello All,
I am having an issue with mixing for mech brakes. I am pretty sure I have done this correctly having researched on here but you never know, I am knew to electric. I dont seem to have power to the Aux on sr3100 when mixing. I dont believe it is the servo (hs7985mg) as I did move the servo to the str port to test and it did work fine. This is a new sr3100 but I suppose it could be bad, I dont know. Any suggestions?
Thanks,
Mark
