Enjoyed both videos--great, great work, though I wouldn't be comfortable flying so high above a city. I guess you were flying manually in the second video, as there was a KPH gauge and no course map. On both videos, I noticed that your compass was wandering crazily. Sometimes it looked like you were maneuvering like in a dogfight, yet the video remained steady. What's up with that? I hope that's a simple fix.
Besides your skill as a pilot/videographer, I really like the data display. Did you come up with that, or did you buy it somewhere? In any case, it's really kool.
