Went out to the desert yesterday and had a great test flight. This is a shot of our first prototype. Some of you may have seen the the #2 plane at the Golden West test at Florida jets. I will try to post some in flight shots later.

Enjoy

Couple of more shots of it in the air. It is such a great feeling after working on this for so long to see it up and flying.

Default more pics

The pics of the above plane is the number one prototype built by Tad and his staff of Golden West. There is so much lift generated by the wing, that during the high speed taxi test, the plane became airborne, so away they went.

I wished that I could have been there, but I plan to make the next hop session for sure.

Follow the below link to some shop pictures of the number 2 prototype, being built by Henry of HVN Custom Models. This will hit the ramp totally dressed up as the Attack version of the T-37 Tweet, known affectionally as The Dragonfly.

Good Job Henry, and Tad.

...looking forward to when they get this "monster" all ready kitting.

As the fortunate soul who got to test fly this bird I want to thank Tad.
The Dragonfly is big, 132" of wing, about 18 square feet worth. The plane only weighed 41 pounds for this test flight, making a wingloading of about 42 oz. / sq. ft.. On a plane this large, that is nothing. This combined with a symetrical airfoil of over 4" thick makes for one sweet machine.
This model was powered with twin 17 pound thrust turbines, makes a cool sound. I didn't make it to full throttle on the takeoff, it flew off at just above half throttle, climbed well, and figured I'd get some altitude prior to openning it up. Aileron control was strong and smooth, good elevator control, and stable in all axis. I would bet this airplane will even fly well on one turbine should the other one ever fail.
The Dragonfly flew more like a 1/3 scale Extra than any jet I've ever flown. I would estimate normal cruise speed at a very scale, and manuveurable 100 mph. The lift of this huge wing makes (with flaps to) resulted in one super slow landing. I don't know if one can get hold of the video of the landing, but the touchdown speed was incredably slow.
I can't wait until the next time I can get together with Tad and terrorize the sky with this bird, aerobatics, touch and goes, and general flying with this giant scale warbird is cool, and I want to stretch the limits with this one. Tad never gets scared by my flying, does he?

ps. you better have a good Golden West Fuel pump to fill this bird, it holds over 6 liters of fuel, enough for some long flights.

Default Whoops

I forgot to mention in the last post that its not a full size HotSpot in front. Thats the Baby HotSpot built by Ewald Schuster, I believe it has a wing span of 40". The most amazing thing about it is not its size, but the tiny tiny turbine that he built for it. Ewald's tiny engine is about 2.5" in dia. and 3.25" long. It is the cutest thing I have seem and it sounds great.

Default another one

one more for here,
A lot more have been added to the H.V.N. Custom Models site, go have a look at some of the nice scale detailings that Henry has incorporated, like "working" trim tabs, stores racks, landing light and lots more.

Tad is gotta be one proud pappa over this, eh Tad.

Now can I get on the list to fly it?
