I wasn't prepared for the change in perspective! I was momentarily confused (1 minute into the video); then my wife shouted "Pull up, pull up!" I slid the glasses back and saw the plane dive
, killed the throttle and pulled up just in time.
I tried again once I'd regained altitude, then flew smoothly for 10 minutes. It was helpful to have a spotter - I lost my sense of direction several times despite having watched numerous keychain camera vids of the site. I finally started orienting to the shapes of distant hills.
The video signal was good to the edge of the soccer fields, almost half a mile. It flickered a time or two, but I just did gentle turns until it locked in again.
I wasn't brave enough to land FPV due to trouble judging altitude (hints welcome!). I slid the glasses back as it passed overhead, then landed LOS.
Afterward, we did a ground test at the University of Alaska. The video signal was strong at 0.5 miles but barely detectable (lots of snow) at 0.7 miles. The Dx6i still turned the rudder at 1.1 miles. Beyond that, trees obscured the line of sight.
I have a patch antenna coming for the Dx6i. Now I'm pondering how to improve the video range. 5.8 ghz 600 mw transmitter? Switch to 1.3 ghz or 900 mhz? A solid signal for a mile or two would be cool!
try finding some landmarks (large buildings/soccer fields/highways) before flying, and rehearse with yourself where and how they are located with respect to your starting/landing area. Check out the area with google maps from various heights and angles.
Maybe you can start with your goggles on? Taking off from the snow sould be an easy feat for the ES
It's difficult to compare ground range with LOS range. My 200mW 900MHz HK provides reasonable signal up to 1 or 2 miles range (with 2 home made 120 degree Y antennas). But if I mount the set-up on a gound test-vehicle...
... I can hardly make it down the driveway of my house, before the signal disappears.
