Barrett: Kindly allow me to bring your attention to site guideline #11:

"Share. Although we are not limited to open source projects, the ones that tend to get the most participation tend to be open source. Don't wait until your code or design is "finished"--post it as it is, and you may find that others will help you finish it faster. The best way to contribute is with your creativity--we love data, code, aircraft designs, photos of UAV projects, videos of flights and build logs. Post early and often!"

 

I'd personally be more responsive to outright commercial advertisements from members who have been mostly silent since 2008 (and did not directly contribute much even then) if you shared the plans for free rather than offered them for $250. Or if you elected to contribute in other ways. In fact, if you offered the plans for free, then some people might purchase parts (maybe not entire kits, but parts) Just a perspective. 

 

No offense intended, just a suggestion.

Of course if you are not in a position to share plans, or help other members with ideas and solutions, you might offer your local Arizona friends from DIYDrones some spare hours here and there in your wind tunnel ;-)

Thanks for the thoughts Mike. 

I'll definitely be more active in the coming years. I've been extremely busy with college which happened right after I initially joined. But now I'm living the dream! Building and designing UAVs (quite frequently crashing new experimental aircraft). I'll formally and publicly make the goal of answering one post a day for the next 3 months. I've got plenty to give, and still plenty to learn. 

Thanks again for the feedback Mike, and I'll talk to my partner about the offering of plans for free, sounds like a good idea to me.

Yes, but the difference is that they contribute. He's already offered to share info, just give him $250.

The recommended power plant for the P-10C is the Desert Aircraft 100L (http://www.desertaircraft.com/engines_detail.php?Page=DA-100). For those on a more frugal budget we recommend the G62 by Zenoah. 

The recommended power plant for the Shadow and the Pioneer is the Desert Aircraft 50R http://www.desertaircraft.com/engines_detail.php?Page=DA-50-R

Check out the "Watch video of conversion." link.

Can you share some details of this crazy beast?  With a payload of 60+ pounds it must have a pretty big motor?

What I can tell you about the spinwing is pretty limited.

There is a great document written by Randy McDonnell (the man behind the idea), which i've attached. It explains quite a bit of the fundamentals behind the aircraft. 

Another piece of the spin wing puzzle is that it's been tested powered in the vertical and horizontal flight profiles, but the conversion tests have only been done unpowered. I'll ask what power plants were used in the powered tests.
