Fairly Limited Capacity
On the Yuneec website we can see some figures showing a fairly limited capacity.
Max Takeoff Weight - 946 lbs
Smaller 6 pack battery - 159 lbs
Empty Weight (w/o battery) - 392 lbs
Since it's a two seater, calculating out the max average weight of each person with no cargo at all it comes to a mere 198 lbs.
If it has the 10 pack battery instead of 6 pack that drops to 145 lbs /person. Granted it's a niche product but they should've never put a 2nd seat in with so little margin, IMO, and I haven't even factored for the weight of a parachute or two, flotation device, etc, and a few pints of ale onboard.
