...that Percy – The Pulsing Parrot – was, in my opinion, the simplest of all published Jack Headley designs. Published in the July 1979 issue of Model Builder, this single channel glider used a part that might be difficult to source today.

Remember L'egg's Eggs? Those egg shaped containers with panty hose in them? Jack re-purposed one of those for the 'head' of Percy. Add a bit of 1/4 sheet balsa in the shape of a beak, some lines and color in the right place and you have a parrot (or a facsimile of one)! Today we've got all manner of shaped foam items at the craft/hobby chains. A foam egg in the right size might be easy enough to locate. Slice it, core it and apply it. You might even find some plastic Easter eggs in the appropriate size to employ. They are usually already colored and require no painting.

Another item of note in this article is that Jack defines a Jedelsky wing. Quoting from the article, "The all sheet wing uses the Jedelsky airfoil, which consists of a small chord main wing section followed by a large chord flap." This technically perfect description comes from someone trained in the discipline of aeronautical engineering. Previous blog posts, discussed the Jedelsky wing - #24 & #23. The polyhedral would be a tough build using foam boards. Chord rigidity is obtained from the ribs but, the LE and sheet provide the span rigidity.

With our micro servos today, a 2 channel version is not out of the question. If the wing pod were expanded...Continue Reading

Apparently I lost track of time since my last entry, as I forgot to make one yesterday.
Oh well, that's okay... I'll just have to double up this time...

Surprisingly, it seems that my previous entries have drained me of anything significant or decent enough to expand into a post, so... I suppose I'll skip ahead and rant about one of my other designs until I come up with something.

Right, even from the start, it seems I've always been quite fascinated with higher speed models, though everyone may experience this from the beginning, so it may not be just me.

So... with the (somewhat surprising) success of the Striker, I figured I'd attempt to take things a step further. I really wanted to construct a better model of the the hand sanded foam Shrike that I built initially, but I really didn't need two of the same model floating around in the "hangar."
So, I suppose... As I normally do, I attempted to make it better.
I rebuilt the original Shrike from the ground up, and gave it a personality different from its original counterpart. And so, the Shuriken was born.
I originally dubbed it the Shrike II, but it sounded slightly too cheesy to me for some reason... not to mention, I have no idea whether the original designer would appreciate that or not, regardless of being built as a tribute to one of the nicest mass produced (pseudo tailless) wing kits at the time.

The Shuriken is only 24" across, and if I recall correctly, it's only working with 178in² of wing area, if you include the horizontal stab.
It spins a 4.5" square propeller, strangely enough... And it pulls a good 19a at 100% throttle, static of course. Surprisingly, I get close to 90mph out of this little beast... Not bad for budget hardware.

Over the next few days, I'll rant some about some of my more unusual projects, but for now... That will have to wait.
Until next time, of course...

To Be Continued...

Well, about a week ago, whilst browsing the classifieds, I came across this very neat vintage radio and having done several 2.4 ghz conversions of older radios already, I decided to jump on it. The price was absolutely right ( a princely sum of $10 plus shipping), and I must say that the seller, birddogs2, was an absolute pleasure to deal with. Before you knew it, the radio was at my door a mere 2 business days after shipping from Oklahoma to Florida. It arrived unharmed, and after a mild cleaning, looked as though it had rarely been used, if ever at all. This little guy was at very least, very well taken care of over the last three and a half decades.

So, a little info on the transmitter. It's a Tower Hobbies TH-6, which as the name denotes, has six channels (5 proportional and 1 switched), and was made in the U.S.A. by Kraft for Tower Hobbies in the 1970's, and based on their Sport series of radios. It has partial metal, bushed gimbals, and an all aluminum housing. It's just absolutely cool! Plus, I had never seen one quite like it.

It even arrived with four vintage servos (a yet unknown brand to me, but they're three wire, with metal housings.. built like tanks), vintage switch, and a Consumer Hobby Corporation Model VI receiver, also with a metal case. These things are heavy, and constructed solid! I can't imagine the weight penalty that this gear would have imposed on even a .40 size bird! Surprisingly enough, once fired up, the servos and receiver still worked!

I officially started 3D Printing part for people on here this week. I look forward to helping people out with replacement parts, custom pieces, and making ideas into physical form.

I'm offering the service pretty much at the cost of materials and time on the machine; doing the set-up and minor design and tweaking without additional charge. So far I have printed electronics boxes, motor mounts, cowls, and some brackets.

If you're interested in having something printed, please PM me.

Up to 210x210x210mm (~ 8"x8"x8")
ABS/PLA (I prefer ABS)
Various Available (I almost always have Black, Grey, White, and Clear on hand)
200 or 300 microns (100 microns available for an additional fee)
Additional Design Fee:
None if you supply the .stl file (or Sketchup, 123D Design, and Tinkercad files) or it's a simple design.
I can provide a quote for more detailed designs.

$3 for shipping to the lower 48 states
+$1.50 for every 25g of material
($5 minimum)

I'm hoping to use this as practice towards designing and making 100% 3D Printed RC Planes (everything but the electronics). I'm starting with ultra-ultra?-micro (Less than 10" Wing span) and working up to ultra-micro (Less than 18" Wing Span). I need to get more familiar with all the print settings and material properties first, to really take advantage of the technology and create innovative designs.

I am using my old oak computer desk that I made about 25 years ago as my build desk. I have made a temporary shelf system for the back of it. I have my bench top tools on a platform just a few feet away.

This actually makes a fairly usable build area.

Swift 3-Axis Gyro Stabilizer Handheld DSLR Gimbal (Plug in and Play)

The Swift 3-Axis gimbal is specially designed for perfectly working with cannon cameras 5D/6D/7D/60D/70D DSLR with different lens. The cameras and lenses can be quickly and easily dismantled. Unlike other gimbals, it uses common NP Lithium batteries, which is greatly increasing its battery commonality, some other battery models such as NP-F550(1h),NP-750(3hrs) and NP-970(5hrs) can be used on it. Besides, the power of battery can support the cradle head, joystick, monitor and all of the devices working processes.

1. Quickly and easily dismantled, very steady and light (only 2.5kg)
2. Conveniently joystick control (Pitch control).
3. Suitable battery models: NP-F550, NP-750 and NP-970 (not include)
4. Designed with landing skid, can be placed in the ground.

With Powerful big-sized
- Brushless electric engine, the Swift comes with dynamic loading capacity. It is easy for Swift to load different kind of camera, lenses and other accessories, etc. There are 3 groups of non-brush electric engine maximizing the torques' functions at power consumption.

It comes with Strong and Durable Structure.
- High quality material makes the Swift strong and light .(only 2.5KG)
- With aluminum and carbon mixed structural design, it makes the Gimbal comes with high-strength structure to
finish some high load photo shooting action. And it's with a special tripod design, you can lay down the camera...Continue Reading

When in doubt, go to the source.

I bought that little Thunder Tiger Bearcat I've been blogging about from the Pegasus Hobbies booth at the AMA expo. They just put the receiver-ready version on their website, in fact.

Gave 'em a call with the part number...success! My credit card is only eight bucks lighter.

It'll get the Suppo outrunner and ESC I used in my Frankensteinian Flyzone Cessna, now retired after its final crash. For that matter, I got that motor and ESC at the AMA about four years ago and it has very little runtime since that Cessna spent more time tip stalling and crashing than it did flying. It just isn't worth repairing, but it was fun while it lasted.

Oh, and I'll fly it with a computerized spread spectrum radio. 27MHz is so 1990s.

No, no resolutions - I never follow them through anyway
However, as I get a little older, I become a bit circumspect about what unfinished projects are still laying around the workshop and garage and realise some hard decisions need to be made (I've done this purging thing a few times before).
Because, building is my passion and flying less so, there isn't a clear-cut goal of 'hurry up and get it built so I can fly it' In fact it is often 'this is building too quickly - and I like what I'm doing a lot'. The end result is many models started get to the interesting phase and then lose their appeal (for me). Sadly, this has happened to a couple of my models that were started some years ago and which have been cluttering up my limited storage space waiting their turn on the bench. As much as I try to convince myself that their turn will come, I know deep down that many other projects are in my sights and spending more time on the uninteresting old ones will not result in much satisfaction.
It must be said that ALL my unfinished models have given lots of building satisfaction and have left me with a better understanding of problem-solving, new techniques and generally greater modelling experience. So after all that self-indulgent waffle, what is being given the 'Cease and Desist' treatment.
My rather ambitious He-111 was built from old plans and could still be hacked into a reasonable model. The rather complex 'glass house' cockpit suffered a bit of damage in transit to our new...Continue Reading

At the beginning of 2015, I paused to try and remember what had I done last year?
It slowly came back - the scale build-off and the great little Polikarpov that Peter Rake designed and I built - a delightful project of an aircraft that had appealed to me for some time. I loved the fast build and had time to try a few simple detail ideas.
Then I got a burst of enthusiasm over the big Hutson Anson. A lot of frustration working from old plans ('80's) and fair-to-awful laser cut parts (always dicey when cut to hand-drawn plans) and new territory with a biggish model, but it was a challenge and involved engineering and woodwork and a subject I adored so progress was fast.
The Anson gave up time after a few months and a previously started Lysander was almost completed (just some servo wires to the wings to sort out). I need the experience with Polyspan to do many awkward panels on the Anson and so decided to practice on Lizzie first. I am almost sure I can do what I want on the Anson now.
Now throw in a Rake Ryan PT-22 which was built and flown in only a few weeks and all that is left is a big effort on the 1/4 scale SPAD XIII. The SPAD hasn't officially flown but it has been fast-taxied and has gained an altitude of two or three feet before I noticed one of the wheels had fallen apart and so was promptly landed while I still had some strip left Ne wheels have been fitted and await my temperament etc to prevail.......
That just about sums 2014 up! Add into the mix, a bunch of annoying health issues for my wife and myself, a lot of home renovation and gardening and I was running out of steam - rapidly! Consequently 2015 has been rather slow so far - my long awaited desire to paint a 'Brisfish' version of the Bristol F2b fighter has been started and some hard decisions about old projects made.
So that is all very much for-what-its-worth sort of stuff.

I've just launched the new UAV not Drone podcast. In the premiere episode I explain the purpose the podcast, along with my background in unmanned aerial vehicles. I discusses the use of the word “drone” and its negative connotation.

I also talks about the AirDog, an autonomous quadcopter with a successful Kickstarter campain and their latest prototype unveiled at CES 2015.

Finally, “Drones in the News” a segment that highlights the latest stories that the media is talking about.

Please give it a listen. Your comments and suggestions are more than welcome.

Thank you!
