Hi Bruce,
We had problems a few weeks ago when a few of us met up to fly together. Three of us had the 200mw 5.8ghz Hobby King kit and we found that, no matter what channels we all selected, if one of us turned on our plane on the ground, it wiped out the signal from any planes up in the air. It was understandable, since we were all within about 20m of each other on the ground while the planes were 100's of meters away in the air (scary stuff if you were the guy in the air), but I wonder if you could address this in your FPV videos. Is there better quality receivers, or transmitters, that will be more exact about the frequencies? Should we have all stood 50m apart (can't really chat then)? Any other ideas? As it was we just took turns in flying, but really the point was to be able to get up in the air together.

PS, Will your video backpack have channel selection? Also, please add audio to it, being able to hear your motor is very handy.
