Hi, this was just a first test flight to see what the LiIon hype is about and it didn't disappoint at about 24min flight with HD recording turned on, the cells were only 96% charged because I couldn't wait the full 3h to get them fully charged like the datasheet says and on most charges you can't set the cut-off current at all. I've went with a 3S setup to keep the battery weight low and tested it on my current 3inch racer that was not modified in any way, sorry for the wobble the PIDs were set for a lighter 4S setup that I normally fly with this quad and it was a bit windy after the rain.
Flight time could be increased with lower a VTX output setting, a lighter frame, no GPS, no HD recording or better still by not using a runcam split camera which consumes too much power (like 10x of a regular camera).
I'm now working on a lighter 2S LiIon setup for more flight time and better batteries, because at 300g AUW it wasn't very fast or responsive, also when using LiIon cells you have to remember that the voltage sag near the end is quite high starting at 12.6V(40% hover) and ending at 7.5V(60% hover), also the cells can't deliver so much current when needed.
Sorry about the corner artifacts, I think that's a youtube compression issues, I didn't see it on the original video file from the camera.
