Amazing signal

I'm an utter novice. Can you tell me how you can control the plane at such a great distance? I thought most RC stuff could only propagate a signal a few hundred feet at most? When I see distances like this, and such good video, I wonder if a remotely-controlled helicopter could deliver envelopes or very small packages to faraway points in the city, such as those yoiur Zephyr visited. It could create a whole new kind of messenger business, as I see it largely due to the ability of the signal you generate to access the camera from quite a few miles away. It would appear to be relatively simple to make drops on the street, even, and certainly on rooftops. But could an RC helicopter actually do this?

no, won't be possible. we weren't flying over and through the city for this reason. R/C signals don't propagate well between buildings, and new york has a lot of interfering sources.

R/C control is maintained by using the EzUHF system. there's a thread here on this forum about the system and what it can do.

Trappy, I saw the video on Drudge, it's fantastic. The truth is that to accomplish what you have takes time, money, patience and skill; you cant just duct-tape a camera onto a $99 dollar special and fly it. So all of the people worrying about imitators, stop. If they go about it the right way as Trappy did, there wont be much to worry about.

A side note to people posting here, radio propagation refers to radio waves bouncing off of the ionosphere and traveling hundred/thousands of miles. UHF signals are line of sight, and do not "propagate" from the transmitter to the receiver.

Also, as any licensed ham can tell you, VHF (50 Mhz old school FM transmitters) or UHF systems have a range limited only by the line of sight and your equipment. Voice contact up to 10 miles on amateur radio on these frequencies is common; and we routinely bounce our whopping 5 watt signals off of satellites and up to the international space station.

Whatever you do Trappy don't remove the part of the plane from the footage, I think its TBS's Trademark .
