Dean,
You dont have any old pattern kits laying around do you? Would LOVE to get my hands on some,, especially the MK ones. I am building my "sport" flying airforce out of this sort of thing, My ugly stick and others are not as much fun to fly as my ballistic style Kaos! and my Pylon racers,,,, by the way its electric,,
The Aurora "30" will be electric too, goal, manuevarable at 100mph, should provide some fun at the club field!

 I have noticed a lot of that syndrome, funny thing though, even some manual drafting guys use a lot of ellipse shapes. In tracing the Aurora, virtually all of the formers when traced, related most perfectly to ellipse's. The top formers are perfect ellipse with axis on the wing centerline, the lowers are centered on a sloped line, lower in the back.
Bob, really sorry to hijack your thread, its not right, this is a fantastic effort, I feel bad now, all the ideas I have had for years are coming to reality,, ( in other peoples planes lol)
here is my effort to tie it into your thread,, the Aroura will use a set of the Eflight retracts,, and its electric,, ( does that help?)

I have two drawing boards and will gladly sell one of them! 

I know that CAD is the way of the future (Just like electric...), but I still enjoy drawing those long, swoopy lines on paper and then being able to look at the resulting drawing from many different perspectives to get an idea of what it will really look like. In other words the analog method of drawing still has its place.. 

Recently I've been working with Bob Kruger, who is becoming very accomplished at making CAD drawings with the swoopy curves intact, and we've worked out a method of producing drawings in which I send him very accurate pencil drawings and then he scans them in and overdraws in CAD. The first of these that the modeling (or stunt) public will see is the Gene Schaffer designed "Oosa-Amma" (The original Stunt Machine - the one before the published one). Bob is doing the CAD plans and we will donate them to PAMPA to run along with an article on the Oosa-Amma that I am writing. I'm building an Oosa-Amma right now to provide some construction photos to go along with the article. I also have quite a few photos of the original plane, which I have just returned to its owner, Andrea Moore. Her husband, Ray Moore obtained the original and had it in his basement at the time of his passing. Andrea graciously lent the model to me to measure and draw.

The Oosa-Amma is Classic legal and is large enough (approximately 625 square inches) to utilize one of Randy's PA 40 R Ultra-Lite engines, and that's exactly what is going in mine. I know that it is politically incorrect to write about glow stuff here... Tough. In fact, I'll post a couple of photos of the original one that Gene designed in 1969. I'll also post a photo or two of some of the components of the one I'm building.

Later - Bob 

Hi Bob,

I really like what you're doing with Gene's planes.  I can't think of a better person for the job!

Is there a whole lot of difference between the "Oosa-Amma" and the "real", not yet published, Stunt machine?  Other than Classic vis a vis Nos. 30 legality?

A few projects are ahead of either right now, but it would be interesting to know the "differences".

I know that it is politically incorrect to write about glow stuff here... Tough.

  LOL!! Being "Second in Command", I can allow a "touch" of lee way on topics in a thread! LOL!!  I can't really figure out what politically correct means, anyway..... 

Can't wait to see the "Dually" in action!

Thanks,
Bill

LOL, There is a guy in California who is re-popping a bunch of the classic kits, among them is the Aurora, glass fuse, foam wing.

I have an HP 40 that needs a ring? or hmmm
I have a line on a 40 size Mach one that is haunting me,,
The Aurora I am redrawing is slated for laser cutting, then kits will be available with the glass belly pan, I am trying to engineer it so that both Glow and electric are feasible,, its a challenge. right now looking at a Hacker A30 on 4S 3000 mah packs. 500 in^2 and goal is less than 4 pounds using average wood. the only block will be at the vertical stab to fuse turtle deck transition. everything else will be molded balsa over formers instead of the standard MK machined blocks to carve.

I have a preflown glass fuse 60 sized pattern ship. No one seems to be able to tell me what it is. Looks a lot like a Dirty birdy, with anhedryl, but the canopy has a flatspot on the front,, sigh,,
It WONT be electric,, I have the Rossi helicopter engine with pipe to  put back in it after its refinished,,,

hmm how to bring it back on track again,, uh,, oh several other MK kits are in the works for resupply, in the 20 to 25 size, makes them very affordable for electric conversions,,
 

PT Granderson is the master of the swoopy line.  His name came up Sunday.  John Witt brought his electric ARC Impact over to show us.  He parked it under my glass coffee table.  The table has a curved, beveled edge, and the several overhead lights cast swoopy lines on the monochromatic plastic wing covering.  We agreed that it looked Grandersonian, and pictures were taken so the effect could be reproduced in the trim scheme. 

Just a couple of the many 'swoopy doodles' in my puter.  I use a drawing program not CAD.  Can do very accurate drawings such as the Elroy's template for motor mount with cooling holes.

Hi Dean

There is no limit to drawing curves, all curves, elipses etc.. and lines can be drawn in AutoCad and many many other CAD and Draw programs, I have very nice curves in my Eliptical Ships

Regards
Randy

Hi Randy,
Of course there is no limit, just a little effort required; but what I am talking about is how what is convenient has a subtle (and maybe unwelcome) influence on what gets drawn so often. I actually keep an old Windows 95/ "ME" machine alive just so that I can run my old copy of Visual Cad as well as Autocad, because VC has some killer curve drawing facilities, intended for use in cam drawing.

P.S. look for a PM

later,
   Dean

Looking good bubba. Will it be ready for 2011 Nats?

Bob,

But I miss the tail cone pipe exit on the bottom.  It looked cool. 

Hiya bob : See you there..

I think its smart you dont compete in Classic.  You need to put all your focus on getting that Twin running, as always you will be prepared and it will be world class. Just dip your toe in the water with the twin, then after that go for a 4'er...

Keep us all posted so to speak ENJOY NYE Everyone.

The base coat/clear coat systems for the color make painting a model a whole lot easier!  And it is much lighter!  Only problem I have seen is putting on the clear to "heavy".

Pretty quiet here, what's the latest Bob?

Hi Wayne,

I just talked to Bob today. His plate is too full right now to work on his twin as much as he would like to. Between working on our PAMPA STUNT NEWS MAGAZINE around 45 hours per month, and running two businesses, I can't imagine where he finds time to even touch his own models. But knowing Bob, he will somehow find the time and provide us with another progress report soon. I think we all owe Bob a lot for making the PAMPA SN such a great magazine that we all enjoy throughout the year. I am always amazed at how much time he donates to the PAMPA project on our behalf. Without his 45 hours per month volunteer work we would not have such a wonderful periodical and Bob would have the time to finish his twin much sooner.

Regards, 

I have no clue how Bob does it.  I believe he has actually cracked Einstein's theory and has set times where he turns the hands of his own clock back!

Einstein also said that if you are very quick, the time goes somehow slower 

flying under too low ceing





and over too high ground :- )))))

Yes ...
Mongo like!
   Dean

Sweet!  BTW: what are you using to attach your CF veil?

Bill

Looking at the photo of the model, there is room for a 3rd motor in the nose.....

Hi Bill,
Isn't there always a STORY ?

Dean

Obviously there will soon be a very sleek and stylish nose cone added to this ship.

I have been trying to come up with a suitable nose joke to no avail, but this reminds me of a story.  One time in 1968 I was in a Shakey's in St. Louis.  I saw a woman who looked very familiar.  Specifically, the profile of her nose looked very familiar.  I later realized that it was identical to the wing planform of the Concorde.

This may be putting the cart a tad before the horse, but are you considering kitting this spectacular beastie, maybe as a component group? Of course you will need to prove it flies well enough to satisfy your design goals but I think that is a safe assumption.

Looking great.

I see you made some good progress on it this week. I can't wait to see it with the Nacelles on it they really bring the style out.As you know I'm looking forward to seeing it finished. Sometime this summer I will hit you up for a flight on it.

You're BOTH Mongos, ceptin' Dean-O is a little closer to the ground!

Ward-O

A low CG is good ... better handling, you see.

On a note more tied to the discussion: I just love how the fixturing falls out of the construction process.
Way to go, Bobba!
  Dean

Its amazing how strong .02 Veil is once you hit it with Zap - Often I will coat the inner half of a Moulded Shell with Carbon Veil to keep it from loosing shape in lieu of using bulkheads.

Just need to watch out when it flashes off - can mess up your eyes like oinions !


Love the detail in the photos' I dont know how many people realise some of these photo's are taken specifically for our viewing purpose they are not simply workshop shap shots. Carefully set up, well pictured and uploaded - all that takes time - We all appreciate your efforts. - Photos make the forum alot of fun.

Keep up the great work. Its defenetly ATD compliant. ( Attention to detail. )

A tri motor set up on electric would be just too cool.  I don't believe the wind would have much to say with the usable power that would be present.  And with the systems becoming "smarter" everyday, it appears, it would take more than a mild hurricane to ground the model!

Great looking work, Brother!
