Yes, the could have written anything there. What matters is what the weight of the combination is to achieve that range (even in theory). It takes a lot of energy to fly a plane with aerodynamics such as this one, far more than your typical glider and batteries are very very heavy. Also there wasn't anybody on board. If this whole contraption weighed more than 100 KG for the demo I'd already be very impressed, even more so if 80% of that wasn't battery weight and if it could stay aloft for more than the one minute demo. This is not so simple. |
