My question wasn't about changing the size of the propellers. I was wondering if one would get more range by substituting a battery pack for a gas tank and a tiny generator.
- falcolas 10y agoIt's still a weight problem. Gas engines and generators are heavy. You also have to add a capacitor system to handle spikes in demand for sudden maneuvers or stabilization jumps in electric demands. Increasing the weight increases the engine & prop size, which increases your energy needs. EDIT: From the few multirotors with a gas engine that I've seen, the right combination of weight - maneuverability sweet spot appears to be around the 750mm size - around 2 feet in diameter. They also tend to have good flight times, but still in the sub-one hour range. Again due to weight.
- mcculley 10y agoI get that one still needs a capacitor or battery. My intuition is that this is still better energy density in watt hours per pound than a battery. Maybe I'm just too used to old battery tech.
