Excellent. That's a great airplane, a Beech 18, I think. If you're gonna crash, that's a great airplane to crash in because of its monocoque construction its stresses are in the skin.

Go to 4:33. Bikes and planes work better when you add lightness.

Here's another great "tricked" Cub which won the shortest landing roll, Valdez, AK at just a little
over 10'. Empty weight on that delicate little thing is 800 lbs.

Very impressive. I wonder what its normal airspeed is (or would be with
full covering of the fuselage). And what sort of weather it may be
limited to. Any idea?

The Piper J-3 was built in a number of versions with engines ranging
from 40 to 65 hp. Catalog listed empty weight was 765 lbs, with the 65
hp engine. Cruising speed for the 65 hp version was stated to be 75
mph.

My father belonged to a flying club that owned a J-3, I believe with
the 40 hp engine, and a steam train could out run it is there was any
wind at all.

They were a bit rudimentary. No brakes and the fuel gauge was a float
attached to a wire that stuck up through the fuel tank cap :-)

And people wonder why I would never get in a private aircraft.

Actually the no brakes thing worked out pretty well on the grass strip
that the flying club used. To taxi took, maybe, half throttle to get
moving and if you went back to idle the thing stopped moving :-)

The wire on a float fuel gauge wasn't fool proof so most people would
just push down on the wire before cranking the engine and if it didn't
pop back up to it's original position they'd take the cap off and peer
in to see how much fuel they had. Here is a photo looking forward
showing the fuel gauge.
