I know what you mean Mike. For the Primus shots on my web-site I had to bring the plane in low and slow. My wife would track it with the camera and fire away. In all we took over a 100 pictures just to get 5-7 presentable shots. I nearly had to clean my pants a few times as I was flying uncomfortably low/slow to get some of those pictures.

Hi,there is a hobby shop in Germany that sells the curare 10,40,and 60 glass fuse and foam/balsa wings and stabilizers here is the link: http://shop.wega-sunshine.com/index....e8808359aa8c8a
except i don`t now if they also sell to the USA

Grtz Erik

138 € is a reasonable price. They also sell a Blue Angel kit for 148.50 €:

Curare - Canadian Nats - Gimli - 1978. This same runway was also used to land a Boeing Airliner when it ran out of fuel over twenty years ago and had to abort to Gimli.

ah, a Curare on a piped Rossi, the world is right.

This Curare is owned by one of the RCU members down in Texas. I identified it in the photos on the forum on "Lets see your workshop". I saw this model hanging from the ceiling of the RC Hobby Shop in Sugarland, TX in March of this spring while I was in Houston on company business. I had sometime on the weekend to pursue some of the hobby shops and rc fields. Over the last three years I've managed to make it to the NHRC, Space City RC and Dick Scobee RC Field in George Bush Park. All very great facilities, can not even find anything at Home to compare too. 12 months of flying. You've got to love that.

Anyone have photos of the paint scheme on the bottom of the curare's wings and fuselage?

I think the wings and fuse are just one color on the bottom to get a bit off contrast to see what is the top and bottom off the plane.But thats just what i think.

I am investigating some of the Boo-boos on the M.A.N. plans for the Curare'

In the sideview, the wing is shown with a chord of about 14 inches. In the top view of the wing, it measures just a bit bigger than 13 inches. The typical sections shown on the same plan give the chord of about 13 1/2 inches.

Does anyone have a handle as to the actual or measured wing chord at the centerline? I know already the notes on the plan are inaccurate.

William, I just took some measurements off the MAN plan. If you look at the area where the dive brake is on the wing plan view, you will see a dotted line that is the TE of the foam core. I you extend that dotted line to the center line of the wing and measure from that intersection to the back edge of the LE it comes to around 11 3/8" My guess is that this is close to correct and that the fuselage elevation view is too large. Hope that helps. Still, I find that these magazine plans tend to have errors. I'd be curious to know how many Curares Prettner built and how each one differed. No telling what the various kits were based on. There's another kit being sold in Germany, too.

I don't get it....how difficult would it be for MAN to make the Minare plans available?
Anyway, Does anyone have the dimensions: WS, root chord, tip and fuse length????

Minare wing root as shown on plans: just under 12 3/8"
tip as shown on plans: approx 8.5"

It's hard to get it exact since the core templates don't really match the rest of the plans. It's the same issues found in the Curare plans. You just have to build the fuselage wing saddle to fit the wing.

And the MAN cores absolutely don't match the MK kit - they're a fair amount too long chordwise at the fuse.

Don't forget that the wing section on the fuselage side view is usually not the root section when it comes to tapered wings. It's the section at the side of the fuselage, which is a bit shorter than the root is.

did you hold in mind that you cut the cord about an 1/2 inch shorter when u put the hardwood wing mount in?Red line is the foam wing cord green line is the wing cord when the wing is finished. The cord off the wing gets shorter so it fits in the fuse.
I`m building a curare from MAN plans and so far everything looks good.

I had to cut the cores as you suggested, so it's going to work out. Good thing I measured everything before finishing the wings up! Somehow my built-up wing ended up w/ 2 degrees of washin (not good) at each tip so I had to get a foam replacement. I still don't know how I got the twist, as everything measured out great before applying the sheeting. The wing was built on a jig, so I'm still scratching my head...

was it a built up wing then the first one? Because you said it was build in a jig.

I have a Minare plans from a German magazine. Ordered these last year with the help of google translation.

jpurcha, how is the quality of the plans?

The following note came with the German set of plans:

"Correction:

In the blueprint "Minare" is slip in us unfortunately a small mistake, ask we for consideration:

The thereon visibility of the deceit area is in the noses strip area, in which middle extendr drawn, around 12 mm. The drawing should be changed therefore correspondingly de sketch.

The rib outlines are however correct, therefore the width of the wing automatically correctly must fall out in the assembly of the deceit area and/or in the cutting of the Styroporkerns.

Sketch:
"
See the attached jpeg.

I'm not sure of the 11-12 mm difference which the note referes to, I measured the two sets of airfoils on the German plans. The German plans show a foam root and tip airfoil sketch and a built up sketch. Both roots measure approximately 315mm, and the tips 217 mm. The wing planform in which the note refers to measures 324 mm at the root, and 217 at the tip. Canada went metric over twenty years ago. It makes for more precise measurements.

I don't measure a 12 mm difference, but only 9 mm.

So do you split the difference between the root and tip widths for the plan layout or do you take the angle at the trailing edege on the planform. Which in this case is 2 degrees taper on this set of plans.

Does make things any clearer?

See post # 45 above. I've also PM'd you, Dav.

I bet that MK found this mistake and corrected their plans and parts.

Also, check out the site http://www.vth.de/shop/shopfiles/sho...id=43&sparte=2

There are some interesting designs still available besides Prettners. The superstar by Wolfgang Matt; the Kaos; Kwik Fly; Jim Martin's Banshee; Dirty Birdy.

So the note is explaining that the LE on the plans was drawn too far forward and should be brought back 12mm? I haven't had to read German since grad school eight years ago and I wasn't any good at it then.

I don't know if this also applies to the Minare, but on the Curare the TE of the actual foam core is a bit confusing. It gets cut out at the center section and the speed brake covers up another section of it on the drawing. I made this pic a while back but didn't post it. The blue line is the actual TE of the core itself. So, the root measurement is from the blue line to the back of the TE.

Thanks, Dav I measured the section based on your sketch, the German plans have a root rib of 255 and 266 on the planform. There is the 11 mm difference.

So who decides what the correct plan form is for the wing? Do we presume the trailing edge is correct?

Glad that helped. I think one is usually safer trying to measure the actual foam core dimensions and disregarding the pieces of wood that get glued to the LE and TE of the foam. I also think fuselage elevation views are mostly for reference since you never actually build over side views and the wing sections shown there don't depict the true root.

This photo was taken in the mid 80's of a 20 size Curare my mate built and flew. It was from an MK kit and was covered in tissue and painted. The model still exists today in as good a condition as you see here in the photo. It has not being flown much, and has not flown at all for the last ten years. The other model I married. (now if I can just get my hands on this Curare for another similar photo). Matt
