It does raise an interesting question: Is windward a production


aircraft company or a prototyping company? The duckhawk kinda blew


our socks off at Mifflin. Yet, per FAA, there are still only two


prototypes on the registry. Is anyone buying them? Is Windward at all


interested in selling them? And, incidentally, doing the kind of


long-haul, refining, getting the bugs out, customer support, FAA


paperwork, etc. needed for being a production aircraft company? I


count more different designs on the website than gliders of any


design in the FAA N number database!




It's a serious question. I'm a contest pilot and fishing around for


new glider. But I also am a wary customer, and you want a company


dedicated to keeping going the glider you have for the time you own


it and the time the guy you sell it to owns it. You want to buy a


glider that will have several hundred total production run, so that a


base of experience develops on its quirks in the air, on the ground,


and in the shop. You want someone at the company who really cares


about your design, not just adapting 220 pounds of batteries in it so


that it can do vtol on mars.




They do a lot of prototype work, but want to have a steady production


line in addition. The key is "steady", as intermittent production is


more expensive and harder to manage. Even if things go well, I expect


production rates for the DuckHawk will be low compared to the ASG-29


(for example), and because it is a smaller company, there is a greater


risk that it will not here ten years from now, compared to Schleicher


(for example).




If your monetary investment in a new glider must be safe, I suggest you


stay with the big brands; if you can risk some of that investment, then


you should investigate what appears to be a step-change in effective


soaring, and get to know the DuckHawk.




It's been 5 months since I've spoken to Greg, but at that time they had


4+ DuckHawk orders, many major components (wing skins, fuselage shells,


etc) already produced for them, but I don't know the current situation.




My suggestion: Call Greg Cole, and talk to him about the glider, and why


you nervous about buying something so expensive from a small company.


He'd love to have a competitor of your stature in a DuckHawk, so I'm


sure he'll be glad to talk to you. You'll enjoy the conversation, too!




Go right to the source - Greg understands people's concerns about buying


from a small company. He knows they aren't cheap, and that it's a


substantial amount of money for most pilots. But, it's a project he has


worked on for a long time, he's invested a lot time and money in the


concept, and he very much wants it to be successful.






When I first saw the descriptions of the SparrowHawk, I fell in love

with the idea.



Then I started trying to confirm the details. Was it really part 103 legal?

The first thing to check is weight -- 103.1(d) If unpowered, weighs less than

155 pounds; Looking at the specifications page, "Empty Weight - 155 lbs".

OOPS, didn't quite make it. 155 pounds is not the same as "less than 155 pounds"



Well, perhaps there is something that can come out. Or, perhaps it really

weighs 154.6 pounds. After all, Windward Performance calls it "ultralight".

What did they say about it on their frequently asked questions page a while

back?



The SparrowHawk is not certified in any way. It will be an

unpowered ultralight vehicle in the US as defined by FAR 103

(14 CFR 103). Neither the factory nor any other authorities

will endorse it as being in compliance with any regulatory or

certification requirements.



So much for claims that it meets Part 103. I guess you have to buy one

and weigh it yourself.



If I showed that disclaimer to my wife, she would probably make it clear

that she would rather I fly something safe - SGS 2-32, Cessna 172, etc.



To really make a difference in soaring, building a few aircraft is only the

beginning. One needs to get them documented, certificated, and priced at a

point where lots of people will buy them -- then sell lots of them and start

to make a difference in soaring.

I'm not sure why there are so many harsh words for Windward and Greg Cole. Greg is a gifted designer and aerodynamicist with a significant portfolio of successful aircraft including the Lancair Legacy and the certified Columbia 300. He knows what it takes to get an aircraft certified and into production & I have to assume he's determined that the cost couldn't possibly be recouped in the sailplane market.

Regarding Joby's vertical take off concept, It's a start and I'm sure the numbers aren't great for range, but Greg's a master at lightweight construction which is everything for that aircraft. I'm sure he wouldn't have even taken it on if there weren't a reasonable chance of changing the state of the art.

So relax guys and show some support for someone who's taking sailplane construction out of the 1980s and has made the sacrifices necessary to move our sport forward.
