"@frederic reblewski thanks for your comment. It is true that our current hybrid system is about 2kw, we chooose this power from practical consideration based current multirotor application. We also can provide bigger one if required. The mechanial…"

"@zhanggi with a small piece of paper, high school math and physics and a pocket calculator you can compute approximates for a lot of physical data! my comment on flexibility was that your current system is about 2KW so, on one end, if the need is,…"

"@frederic reblewski very good, you estimation on fuel consumption is ver precise. but your thought about the hybrid system is different from us, our system has great flexibility,  it is our most creatvie idea. our H2 system can be used in broad…"

"@Huges we use the tradional two stroke engine/battery hybrid power system, and Fuel cell we tested before showed low power density and high price, so we discarded it. Our aim is to provide proper performance  price ratio hybrid power system."

"@adrian Nagy we have taken great efforts on two stroke and wankel engine, but wankel engine is too expensive to be used, so we insist on two stroke gasoline engine. "

"with a back of the envelope calculation, it should use around 2 liters of gas per hour, which means that durations above 15' benefit from that approach for that configuration. the main drawback is that there is little flexibility in the power…"

"What about using wankel motors instead of otto ones? Vibration levels would seriuosly decrease. Here are some samples in this size: http://www.barnardmicrosystems.com/UAV/engines/wankel.html"

"Very impressive specs, great work! Flight controller/stack? You do seem to have serious vibration though, that's got to be one difficult to deal with problem with hybrid."
