I have a toy quadcopter (syma X5) which I've built onto a custom frame (lighter) and hang my Möbius action camera from for footage.
The x5 has a sister version (x5c) with a removable camera and the wiring is present on my X5.
I have made an adaptor out of micro jst leads to remove the battery from the Möbius and power it direct from the quad's onboard camera supply. I added 2x 100uF caps to act as a reservior., however:
(1) with no caps, the camera works but footage (saved to the SD card) becomes briefly corrupted if he quad goes behind an object. E.g. a tree is between quad and operator.
(2) with the 2 caps, there is a lot of signal noise and the camera shuts down (and looses footage) within a freecycle seconds of flight.
I wonder why it's worse with the caps than without?
