As far as mounting it to the quad, I think having it stuck to the side might be good. This way the GPS antenna faces more towards the sky ( pointing down is the worst , is it not ? ) and after a fly away, there is more chance that it will still be sideways because it's unlikely the quad will be balancing on it's edge . What do you think ?
I'm new to the Garmin 10, but I've used around consumer GPS devices since dirt was invented, and my opinion is that you don't need to worry about the exact positioning of the unit on the Phantom. I just want mine to be securely attached and out of the way of stuff like the GoPro mount and my gimbal to be.
Every GPS will say in the directions that it needs a clear view of the sky, and that is most certainly optimum, but not always necessary for them to function quite well. As All In Austria pointed out, his will report it's location indoors, two stories down, inside of fairly thick walls. That's typical for today's GPS device's capabilities. The first test I did with my Garmin 10 was to take a trip to the store with it inside my camcorder case and inside the trunk of my car, and it later showed a string of locations on the report that exactly matched the path I took. It even tracked me inside the store, although less accurately. However, it was at all times accurate enough for me to find my quad or my dog if they had gone astray.
Something that hasn't been mentioned yet, but that I think is really important features of the Garmin GTU-10 are the Android and IOS apps that work with it. I have both, and either one of them would work really well in the field to hunt down the Garmin if need be.
Again, I wouldn't fret over how to position the unit. Remember, as Botbum indicated, you don't need a disaster with your Phantom to have fun with it. You enjoy reliving your flights by going over the saved tracks of the Phantom, or yourself when you go places. However, if you should decide to do crash tests with different mounting configurations, don't forget to take lots of video!
