Akom's Tech Ruminations

Various tech outbursts - code and solutions to practical problems

Pitts S2A second on-board video flight

This morning I thought I'd test my luck a little more, and mount the camcorder (Panasonic SDR-S10 at 220 grams) on the side of the fuselage. Visually, it just seems safer there - in a crash I expect the wings to protect it. On the downside, it unbalances the craft a lot - 635g plane with 220g of now unbalanced payload! But I did it anyway.

See the video...

Now I knew I'd be trimming the ailerons to the right... Only one issue. From past crashes, the wing was already kind of twisted, so I already had the ailerons trimmed a bit to the right. In retrospect, all I had to do was mount the camera on the other side :-)... But the issue was that now I was flying with heavily extended ailerons, creating a lot of drag, so the plane had to fly at full throttle all the time. But hey - it flew, so I can live with that.

The other thing that happens with ailerons compensating for weight is.... the compensation needs to change when speed changes... such as during landing. As you can tell from the video, I'm not that quick, yet.

The original video is actually very clean, high quality, and does not skip. Have yet to figure out how people convince youtube to keep it that way.
