I finally got around to trying to fly the Pencam SD that I picked up a while back. But I seem to be having problems with the batteries. The first flight the battery door popped open in flight, and I got nothing. A piece of gaffers tape cured that problem. The second flight apeared OK, but shot no video. I know I got the camera started (in movie mode) because I waited for the LCD display to tick before I stepped back and they launched. When I recovered the camera, it was off, and again the SD card was blank.
Ground tests show that the camera functions properly, creating files on the SD card. Has any one else flown this camera? Any ideas on why it keeps shutting off? Are the internal battery springs too loose? Something else?
