I saw it. It was being towed behind that big red Idaho potato truck you see on TV. 😂😂

Hope this link works. Google+ so no guarantees...
This airplane has been discussed here on the forums (years ago), so some of these I got from what was posted here, some I got from Barnstormers. Thought it was interesting enough to save the photos.

Okay, I just previewed the post and tested the link...it works for me...

Enjoy!

Thanks for the pics. I totally missed this when the thread was new.

I wonder why the builder decided to use struts. Must have not used the original center section.

would expect not much room over the pilots head for the standard RV center section :-) ...

I did some investigative work on an RV/Tailwind hybrid. Even have a one-off fuselage CAD drawing still hanging above my desk.

The builder used struts because using an RV center section above your head would mean raising the wing another 4" to 6" to allow room for your head. No cantilever center section, no cantilever wing. Hence, the struts.

The biggest drawback to this design is the headroom problem.

The biggest advantages are:
1) that you can sit in the shade, but most advantageous as we all get older,
2) it's a heckuva lot easier to enter a door and sit down than it is to climb down into a cockpit.

You gotta wonder why Van's doesn't build something different, like this, instead of rehashing the RV-6 design over and over. ???

Agreed. I am sure that a high wing Vans would be ab big success. I mean, the most successful GA aircraft in history is a high wing....

The Bearhawk, Patrol and BH LSA are all RV type wings (strutted) on rag/tube fuselages. They are considerably faster than super cubs because of the cleaner wing/strut design. Good looking airplanes too.

A little extra fuselage height could be useful. The BD-4 is strutless, and the stock fuselage is pretty close to a 2 place with lots of baggage. So it's do-able.

A -14 wing on a high wing fuselage could be the start of a serious bush plane with cross country speed. Anyone care to make a center section with a bit less dihedral?

No, you want to use the -9's wing. The different airfoil will help it land slower.

I wonder if you could build it with external fittings for the wings and avoid the struts altogether?

..how many guys have just gotten out their napkin sketchpads again? ( ok, some autoCad geeks pulled out tablets!).....and started to design,...again?
Most of us have been doing this since they were 7 or so, then kit-bashing old model airplanes into something new.
For the serious addict, there are now CAD modeling tools that will spit out lift numbers and drag coefficients almost instantly.....sometimes I wish I was 20 again and my ol' brain could learn these things!
for now, I'll just say I'm on board, as I am looking for a 'sport' bushplane. Seems most have 32 to 35' wingspans, so Bill's right......I'll have to stretch my -9a wing a bit....maybe extend the fowler flaps to 40+ degrees, droop the ailerons too!....hmmmmmmm gotta get another napkin!.........

beef up the ribs, and skin it with OraTex fabric eh!?
