we tried to get some FPV shots today with the Spark and ran into a few issues.
Camera is powered with a small lipo (6S). One time the camera powered down when hitting record. On every flight the camera self-cut before landing. As there is no record indicator its impossible to tell when it cut (could have been right after take-off). Very frustrating experience but was curious if anybody else had similar issues (e.g. is there an issue with the camera not being able to handle vibrations) or the other way around: has anybody successfully flown the Spark?
Yeah somehow a 6S (even discharged to perfectly hit the 24V) did not do the trick. We ended up flying a small V-mount, which is obviously not great for high-speed, agile shots. I will have to test a 14V regulated input coming from the Lipo - that should hopefully fix it.
Likely a voltage spike or sag. Did the drone have a dedicated power source or was it sharing the Lipo? Having a good BEC and/or a low ESR capacitor in-line should mitigate the power hiccups.
I purchased a Mutiny cable and soldered an XT30 PLUG for a smaller <750 4s Lipo then made a 3d print that holds the lipo in the vmount. Worked fine. One battery gets used per flight almost like the SSD. I have yet to figure out out a servo switch for record button.
