That sinking feeling...

Above the Fog from Jason Short on Vimeo.

This is a video of me loosing my plane into the sun and fog for almost 5 minutes. I was just testing my AP that i've been working on over the last month and a half and it was my first flight with working waypoints. I tuned everything way down, but it was working ok so I let it run loops around the T3 course. One thing I turned off for debugging was altitude control. In hindsight, that was a mistake. I could have just dampened it down more, but I shut it off entirely.The plane slowly climbed the entire time and before I realized it was pretty high. Eight minutes into the flight she turned right into the sun and fog bank and I didn't see it again until four and a half minutes later. I was panicking I couldn't take over manual, because it was in the fog. I even thought about running to the car and chasing it until I realized I had no idea where it was. Last I saw it was headed out to sea. I had nothing to do but wait and count the $ to replace it.I stared at the sky for what seamed ten minutes and all of the sudden I saw it gently doing the T3 above me. I put it in FBW and brought it straight down. Enjoy the video, I edited out the 4 minutes of circling. You can hear me fussing with the radio, and I one point I put it in Manual and turned it left in a futile effort to find it. I just put it back into AP and hoped I did a good job. The plane will fly again.

    Placing the autopilot under the wing, bottom part of the fuselage, looks like the safest place, but not so easy access so not for prototyping.

    I don't think so. I was having issues with the GPS and I fussed with the code too much. I had just put it up in the air and flipped the switch to AP. It started diving and I turned on stabilize. It was totally my fault. I watched it out of control and waited to see if it would recover. then responded too late.

    Yesterday's drop was pure fun. I love the sound it makes when it goes 80+mph. My new plane parts were waiting in the wings so I spent the day building it. I was just hoping to get some more life out of this one because the new plane is pristine.

    I just can't believe how many chips flew off of that Ardupilot board. The Mino is still working; It's a tough bastard.

    Thermopile window got wet in the cloud due to condensation?

    OK, I think that plane just wanted to die. This morning it make a suicide dive and I wasn't fast enough to control it. So in its honor here are both drops in HD.

  • Wish there was a flight recording showing the altitude, but releasing that would probably get you busted.

    I put a wide angle board lens onto my HD mino and didn't get it straight. I left it that way because I kinda like the effect. It softens the sides and make it easier to watch. It also kinda makes it look like I'm flying over a train set.
  • Cool video. :)
  • Still very pretty though.
  • What camera are you using? It seems to have serious peripheral focus distortion.
