For the first ten years or so, they're cheap insurance against a bad day at the office. Recertification, though is expensive. But again, still cheaper than having a bad day at the office.
All the "you can buy more expensive ESC" talk is just plain, reckless stupidity. Companies ALWAYS cut costs. This aircraft has a design fault built into it, where a failure of the engines, batteries, ESCs or lack of energy leads to an uncontrolled dive.
Airplane manufacturers go to extreme lengths to provide safety in their airplanes - even adding BRS to a plane, so it's beyond me why you would intentionally allow a design fault and not correct it with a canard or a front wing.
1.) Ford only changed AFTER it got caught! In this case, getting caught after an accident would mean someone already had an accident.
Also, according to your logic, helicopters should be an impossibility. A single rotor? with a rotor head, that is more or less a complicated mechanism with many small parts that each can fail and each is necessary?
A guy I used to know said you had to keep an eye on the "Jesus Nut" in a helicopter: the one fastener which, when it fails, cause the occupants to yell "Jesus!" as they descend rapidly.
This is what I call any part which is a single point of failure that could lead to catastrophe. The old O-rings on Shuttle SRBs, for instance, were "Jesus Gaskets".

Also, this is just a smaller prototype, the real version looks more like a Scaled Composites VariEze
