The PW-5 wings are like feathers compared to anything else I've rigged.


I rigged the prototype of the Russia-1 - at 11 meters span (L/D of 27
iirc) each wing had a weight of 22 kg. Now this is what I'd call
feather weight...

The test pilot Yuri Kuznezov displayed some nice aerobatics to
convince us that the wings were string enough before we took flights.
