The problems were twofold: first from a distance, it's hard to tell whether you're anywhere above your target, not not. Then, from a greater distance with a smallish plane, it quickly gets hard to know which way your plane is pointing. I even lost it in the sky a couple of times at Rancho when I was pushing distances.
First, I always made sure to have a full battery to start with, and a flight timed to only be half my battery capacity due to how I have to push the motor a lot more to sustain the extra weight, and also keep plenty of altitude so that I could make errors or have a chance to glide somewhere somewhat useful should I lose power (I hadn't quite planned for losing the prop like in the first Google/Shoreline video, but that one worked out quite well :) Then, when I start to lose the plane and can't even tell which way it's pointing, I do gentle turns to raise a wing, making the plane more visible and the turn then shows me which wing is raised and which way the nose is pointing :)
(needless to say that this is somewhat pushing it a little bit, this may not work for you and you may just lose your plane into the horizon ;) Now, given all this, it'll make more sense when I explain that given those conditions, and non live video (recorded onto SD and downloaded after landing), it is
very hard to film something on purpose, so don't be too critical if you think videos were shot badly: that's because they mostly weren't shot :)
Now that this all out of the way, here are the videos and a few frames I hand picked:First, flights around the Rancho San Antonio park:
Then, flights around Google and the Shoreline Amphitheatre:
Better flights of google and Shoreline Amphitheatre (especially 2nd video):
