Hi there, my name is Kyle and I am new to the site. I found Tony's 3gx setup videos on youtube to help me set up the 3gx on a trex 700 gasser conversion I am building. I had everything set the way I wanted it and was ready to go for a test hover when I noticed I could not get from rate mode to heading hold mode. I know this worked earlier, the only thing I changed was I found that the governor should be in the AUX2 channel. I'm running an AR8000 receiver with the satellite, the TM1000 for telemetry info, and a DX9 transmitter. This has me very frustrated since I was ready for a test flight. I tried updating the software on the 3gx to V5 and then back to V4.1 and still the same problem. When i check the gain in the program no matter what I do it reads at 120. I have tried creating a whole new model and starting over in the transmitter, made sure i tried positive and negative values for the gain, tried reversing the channel, and also tried using AUX3. I am starting to think something went bad in the 3gx itself. Thanks for any help.
