Mind me asking which "version" of your product is being used in these videos?

Comment by trappy on June 9, 2011 at 7:25am

ssozonoff, thanks! they have bought the EzUHF/EzOSD version and were using a 14dbi/7dbi lawmate and oracle ground station with Carl Zeiss Cinemizer goggles.

Does this system provide GPS info to recover the plane in case a crash happens in the forest?

Comment by trappy on June 9, 2011 at 7:47am

yes, the current GPS coordinates are transferred via audio-link down the FPV stream. you can record that footage (we also sell a recorder) and then play it through an available windows application, which will give you the GPS coordinates. You can also connect an iPhone or iPad to the audio-stream and it will show you the plane position in real-time. this is even faster for recovery, as you can just grab the iPhone and start walking until the "Home" pin meets the "plane" pin :)

Thanks, so this way all OSD info goes through the audio link instead of the vdo?

What iOS app is used?

Very interesting system.

Comment by trappy on June 9, 2011 at 7:54am

The OSD info is shown on screen "analog" and sent "digitally" down to the ground station. The iOS app is claled "iTelemetry", it's a free download and tied to the system we use (immersionRC EzOSD, EzUHF). You can also receive all other information such as RSSI, Voltage, mAh consumed, speed, etc. Same applies to the windows application, obviously. If you want you can pipe the live-feed to your laptop and receive all information there. But we don't like bringing laptops out to the field.

Awesome stuff. You say no FPV experience.. does that mean they had RC experience? If not, how difficult is learning to fly on a delta wing?

Also, do you happen to have any specs/datasheets/links on the antennas used here? Thanks.

Keep posting the vids :).

yeah, they have plenty of R/C experience. Learning to fly it, and learning to fly it fast down the mountains is 2 different pairs of shoes obviously. I've learned R/C on a flying wing, it's much easier due to the "bank & yank" kind of flight. However, I suggest to start with something a little more docile like the Maxi Swift, or even a Zagi. There's also a handful of simulators out there that can help you get into R/C, which is essential before you move on to FPV. If you rush the R/C part, you'll never fully feel comfortable in FPV.

The ground-antenna used is the 14dbi patch antenna available at most FPV hobby stores. It's pretty basic, cheap and a good beginner antenna.
