They mentioned 83 kWhr battery, a peak power usage of 80 kW, and a "normal flight", whatever that means, usage of around 20 kW. I should note that a conventional airplane rarely cruises at less than 50% power, 65-75% would be more common. But even an hour endurance, plus reserves, is okay for a trainer airplane, so this product is pretty decent already, and your outrage over the waste of your precious time probably was not warranted. If this thing can recharge in ~30 mins, then it would be a pretty good option for a flying school, where pre-flight briefings and checks will consume a part of this time. And given the pre-orders and options, it seems the flying schools in fact agree that this is a pretty good product.
