I just installed an Axial NVS per the instructions. Run the set up. With no control input one blinker constantly blinks. When I add opposite input it stops and the other blinker does work, back to neutral the first blinker starts to blink again. I run a Spektrum dx4s with a sr410 receiver. I've talked to axial and they don't know how to fix, they think it's the radio. My trims and sub trims are at "0" plus my end points are at 100%. Can anyone help?
