I have a new FlySky FS-TH9x (rebranded Turnigy 9X) that is giving me fits. I have a smartieparts programming board installed in the TX and the firmware has been reflashed to er9x. When I plug a servo into any channel, the servo swings back and forth madly or just jitters at best. The red led inside the RX blinks in tune to the servo jitters. I tried several servos with the same result so i don't think it is a servo problem. I bound the TX/RX following the RCMR video steps exactly using a measured 6.4v (I tried 4.8v first but I was still having problems so I tried 6.4 thinking maybe I didn't have enough power). The RX and TX are far away from any other radio equipment during binding and testing so I don't think it is an interference problem. Any idea of what is going on? How do I diagnose this problem? Is it a TX problem? RX problem? Maybe a wrong setting in the TX software? I am new to aerial RC so I have limited experience to solve this on my own. Any help would be greatly appreciated. -Greg
PS-The radio seems to work fine in AeroSim flight simulator software so maybe the TX hardware is OK?
