Just thought I'd give a quick report... The transmitter worked beautifully! F/S and IOC modes worked great.
I wanted to program my switches to match what I was used to on the Phantom's stock transmitter, so it took a bit longer for me to fully absorb it all and make the desired adjustments versus what was presented in the videos. Not to mention that some of the channels are labeled differently from the model in the video. The key, of course, was to simply correlate the channels rather than their labels (e.g. in the video, ch 5 is labeled AUX4 vs. ch 5 labeled GEAR on the T8FGS) -- and then set the respective CRTL that I wanted to use for each. As I said, I'm a noob. So I'm grateful for the leg-up and happy to be flying with my new Futaba!
Since it was well into dusk by the time I finished up, I was able to see the Phantom's lights as I eventually flew out about 1,500'.
Now, about that FPV...
