Compared to a real airplane, yes.

There may be some niche applications, like unmanned surveillance, where they
might be useful but they are terribly fragile.

And a range of 90 minutes....
That's barely enough to start a crosscountry.
If you want a fun machine that goes places cheaply
The Bantam B22 Microlight has a 4 hour range at 60+ knots.

I was referring to the unmanned research things that stay up for days, mostly
because they are little more than gliders covered with solar cells with an
electric motor.
