that first one OUCH!!!
the second one iepes! right in the muck!
third one surprised those geese didnt rip it to shreds!
very cool plane! been looking at building a biplane sometime. plans anywhere or still in the prototype stage?
I have a set of plans here http://forum.flitetest.com/showthread.php?13126-Foam-Board-Jenny/page4 One change I might make to them is adding a lower surface to the top wing.
The struts were foam on the prototype but weren't strong enough in a hard landing. I would take a BBQ skewer for the leading edge of each strut and drive it all the way through both top and bottom surfaces of both wings to give the whole thing some extra rigidity.
The Jenny flew well, but was a 0 wind plane because it was so light and had so much lift from the undercambered airfoil. Making the wings both double surface should reduce the lift, and add weight making it a little more wind-friendly. The lower drag airfoil would theoretically increase the top speed too. This plane is a scale flyer and doesn't like to be over-powered.
