Not really. My point being is just because it can lift a given weight doesn't mean that it can carry it for a significant amount of time or carry it safely. The more weight it carries, the less the flight time, along with reduced performance and safety. This is more of a problem for an aircraft that hangs on props versus fixed wing. That would be bad enough, but the payload basket makes things worse with induced drag and fighting wind gusts, etc.
Back to what I posted earlier, I don't see more than 3 flights in the real world, if that, carrying a delivery any significant distance that DOESN'T weigh that much. This is just based on the amount of time it would need to be powered up and in the air for a complete round trip. Add a pound or so for any payload worth delivering and what are you left with? Not much. So it seems to me that using something the size of the
M2P for what zing is proposing is in the realm of fantasy.
If they want to be taken seriously they need to prove it's possible. Load the basket up with two or three cans of soda/whatever and make as many 1000+ yard round trips on one battery as possible. Do it with a 5-10 mph breeze along with realistic times for the customer to get to the drone and actually unload it, allowing it to make the return trip. And this scenario is for the only one that I see as there being anything close to realistic in terms of market and feasibility due to cost and range - namely running stuff out to boats in a harbor as you suggested. And who is going to pay a delivery charge of 5 or more dollars just to get a soda/beer, etc. on demand when they had the opportunity to plan ahead and pack what they wanted anyway? In other words the majority won't have any need, and most others will just wait 'til they get to shore.
Oh, and the test should also include the drone evading things thrown at it from the angry mob below that's sick and tired of all of the buzzing, etc.
