Anybody can fly an aeroplane, alright?

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 :-)

Cubs had brakes since the late forties. In the 50's they got hydraulic brakes.


I can only comment on what I saw and the J-3 that the flying club
owned did not have brakes.

Oh, I'm sure you are correct. A few J-3's were manufactured in the thirties without brakes. Even when brakes were added, they were not much until they got to be hydraulic. The heel brakes on a '46 Taylorcraft are not strong enough to keep the aircraft from rolling forward during a full-throttle run-up. But they do slow it down, and sometimes a little differential braking can help get the tailwheel to swivel when you want to do a 360 on the ground to check for traffic or scare the hell out of your passenger. I know that from experience.
