"@Heung-Jin Choi
No, we don't use fuel cell technology, it is high price and not mature, we have tried it, now we use regular two stroke gasoline engine and bldc starter/generator as as our hybrid power system.
I don't see AUW in the video, sorry I…"

zhangqi replied to Mr N.'s discussion Hybrid 4 stroke multirotor
"My viewpoint:
The Honda GX25 and GX35 can't be used in hybrid multirotor, we have tried it, the power is not enough, GX25 is 1hp and GX35 is 1kw, and now the most efficient multirotor lift power ratio is about 8~10, so even the efficiency from…"
