Jagdfleiger

Hi Guys,
I purchased a kit of the MC.20o several months ago. I am scale warbird guy who loves unusual subjects. I am into 100% scale. The reason I purchased the "Saetta" was because I thought it might actually have a scale fiberglass fuse and cowl. I finished a bunch of preliminary measurements and lo and behold, the proportions on the model are very close to 1/6.5. The fiberglass work is really pretty good. The panel lines are all wrong, but those can be filled pretty easily. We will have to throw out the wing...its totally wrong. But, still for $125 I am very happy with what I purchased. I plan to do a build article on this aircraft sometime.

I am curious about a couple of things. Not sure why the Chinese picked such an obscure subject. I can't imagine there is a big following for this particular aircraft. Had they done the Mc.202 that would have been a different story. Anyway, very interesting.

Final note. Anyone interested in working on a true scale build with me on this plane. It will be as close to scale as possible. I also have seen an original at the Airforce Museum in Dayton, OH. If we do this, I plan a second visit. Looks like it could be a heck of alot of fun. If anyone is interested, let me know, if not, I will pass on it as I have several other project queued-up.

Sorry, Forgot to post the most important thing....the model. Not sure if its a CMP model or not. Anyway, it can be bought at Raiden.
Here is a link ---> http://www.raidentech.com/itmamcnigasp.html

Corsair 29

In the reference pictures below they show a rounder look at the tips. Is this correct, or the square look as shown on the model?
I'm also looking into this one, but I will add the retracts.
On one of the P-40 brands that Nitromodels sell they used half webbings at the spars, can you verify if this one is constructed the same?

Jagdfleiger

Yea - Like I noted earlier, the wings are all wrong. The Macchi C.200 had rounded wing tips. The wings in the kit are squared off. Also, they are a few inches shorter than they should be. Don't now about their construction, but like I mentioned, I plan to design and build scale wings with flaps and retracts.

I have also one, but this was an old ( ARF with light green wings and fuselage ).
I've changed in a other color, but not flown.

I would love to get some detail shots if you go the the USAM. I think I will be starting an enlarge MAN Macchi C200 for my next build. 86" ws hopefully 25 pounds with a Saito 325.

Carl,
I came across several links a while back researching this aircraft. This one is a superb walkaround of a Saetta painted in the colors of the 362nd Squadron that fought in Russia during WWII. http://www.ams.vr.it/AircWalkAround/...20pag%2001.htm

Klaus could you tell us a little about your Saetta (type of engine? how did it fly? etc.)?

nicostoffi

Hello,
the engine is a ASP 120 4-stroke.This one doesn't fly, I finished it after my heartattack and do not fly since September last year.
She will go to sky this weekend or next one.
The green one, you see fly, was my first Saetta, which I have destroyed after lost the engine.
And there is the problem of the machine.If you make it to slow, she will have a stall.You must land with little more speed.

Thanks very much for the link. These will compliment my books very well! Now to finish the Wildcat and start the Macchi.

Jagdfleiger

Klaus,
Thanks for the information. Hope you are recovering well. Regarding the wing. Assuming its the same one as the one in my kit, it really needs work. I suspected there would be problems with it both aerodynamically and from a scale perspective. First, there is no washout built into the wing. It should have 2 - 3 degrees of washout to prevent tip stalling on landing. Moreover, it does not have the correct wingspan, leading to higher than necessary wing loadings. Thats why I mentioned on this thread that it needed to be discarded. If I get enough interest to do a build thread (or kit bash) on the Macchi, I can design a new wing that will hopefully solve that problem. Its really not that hard to do. Anyway, thanks again for the information.

Rob

Jagdfleiger

Carl - keep me posted if you are interested. Got some of info on the Macchi. Funny, recently completed a somewhat obscure Japanese aircraft (Tachikawa KI-36). The hardest thing in the world to find documentation on. Fortunately had a business trip to Japan and was able to secure the documention I needed for scale masters...only to lose it all in a house fire last year. Oh well! The reason I mention that is that I thought it might be difficult to find info on the Macchi. Actually, it readily available. I was pleasantly surprised.

Rob,
Thanks for the offer. I have four books and a plastic model plus what you guided me to. I would really love to go to WP and have a look see at the real thing. I have some pics of the 202? in the NASM. I will not get serious for quite a few months still. I guess I will just have to do this one next! Don't see any at the field Of course I will not refuse any documentation, can't get any more confused than I am already ;^)

Jagdfleiger did you ever build a scale wing for the nitro models Macchi 200

Jagdfleiger

No, I never did. Plan to though someday.
Rob

nicostoffi

OOOOOH a Macchi Saetta 200.

I told here before.First one had lost the engine and fall down.
I get a second one and changed the colours and the wing ( told it here ).

This one was unflyable.I do´n't know why.
Maybe too big elevator adjustments, maybe C.G. too far back or forward.
The C.G. point was not given by the manual instructions.
After lift off, the macchi will do what she wants.

SEE WHAT'S HAPPENED

nicostoffi

But like we say in Germany

ALL GOOD THINGS ARE THREE.

Yes, I bought a third one.Now it's a newer version.
Light green and light grey, with given all adjustments and C.G.point at the manual instructions.

I must only built this.
Maybe I don't change the colours, but give her a retract.

nico - hopefully you get get this built. I would love to see the pictures and your building recommendations. I'm just finishing up my VQ Macchi 205 - hopefully I will fly it this weekend. I put an OS 70 Surpass on it, and the balance came out just right at 105mm. My wife asked me what I wanted for Christmas, since I just inherited two .61 2 Strokes and a 70 4 Stroke, I'm trying to grease the skids to get another plane, and this one has my interest.

Hello Guy's

I hope this thread isn't dead!

Well I got my Air-Kill-90 MC200 Macchi Saetta today.
Bought it via eBay Germany. It is the middle green one, not the olive drab colour.
Shipped in a plain box, without print. It might be a copy cat, of a copy cat?
The price was the same as a standadard ARF trainer. Relatively a bargain... so I hit the EB-button!
The CG is not written in the clumsy manual as noted in the beginning of the thread.

My plane is rather rough. Paint job is lousy... but wings look straight. All good enough for touch-up to a more scale look. A crude kit so to speak, but it might be fun to fly with some tweaks?

CMPro or VQ are different worlds. High quality brands!

The airfoil looks like a speedy one. Not close to the original Saetta seen on a internet drawing.
A forgiving 2415 or 2315 NACA whould have done better on this plane? Tips in 0018 NACA symetrical and a wash-out of in a +/-3 degree negative?
If this wing has a wash-out, I'll check with the incedence meter when I pick-up the project.

Question remains... Where lies the CG point?

Foto's are one's found on the internet. (Many were butchered by the P-40 Warhawks in the Mediteranian theatre of war)

nicostoffi

Hello,
I told here that I destroyed 2 Macchi 200 and has 1 to build.
This one is a newer one, other colours and with instructions for the C.G. point.

So let me tell you the point is 120mm from leading edge.

When I start building this kit, I will write here.

nicostoffi

Sorry

"nicostofi", good luck with your Macchi 200 that sure you will have as I have been following your progresses on both KMP´s Me 109 and FW 190 and you are a real "Experten", sir.

By the way, in Spain we also have a similar saying to that German one your posted before:

YOU ONLY WIN AT THIRD TRY!.

Best regards from Spain,

Its been a while since I have looked at my Macchi C200. One of the things I remembered though is that the wing is a disaster. I don't know where they got it from - another kit perhaps? Anyway, its planform is all wrong. When I tackle this bird, I will either modify the existing wing (if thats possible) but more likely build a new one that's 100% scale at least in planform. The fuse looks great and is prettymuch scale. Good luck

Hallo Nicostofi,

Danke für Ihres schreiben! Ich habe Ihre Internet Seite gefunden. Ah! Richtig klasse was da alles drinn steckt! Die P-40 Filmaufnahme (VQ/Air Loisirs) ist bereits die Welt rund gegangen!
Ãœbrigens, Ihre andere 'Birds' sind auch sehr, sehr net! Komplimente! (check this via babelfisch!)

Natürlich.... Thanks for the CG info! I'll note that right away in the manual.
What you write about the stabilo/elevator... yes it looks quite small to me too. Might be sensible to make it larger.
But the plane falling out of the sky at landings? Balance, and loss of airspeed on the tips... a mix of those forces... thus a wrong tip profile? or a need for flaps!

You flew your two shreadded Saetta's, first a 80 engine, later the Magnum/SY 120?
The plane needed some progrissive propsize to keep it flying?

And... would a Saito 100 do? I was intending to put my FA-100 in the VQ P40. (this P40 has to wait a bit for a larger P40 CMP 140)

More about props...
It could be wise to fly it with a large prop as possible? ...to keep steady presure on stabilo and rudder?
Or just a bit more mid range size, and higher rpm, so it flies faster?
The cowl is quite large. Prop turns less efficient when to small. Fuse is bulky too.

What is your opinion on this matter?

In my mind I am already drawing a new wing out of Styropor-foam. Robbe Puma II profile... safe wing! Ehhhh, did I buy an ARF then?

RC-PowerBus

Hello Jagdflieger,
Tell me more about this wing. Should I use it to warm my hands on? or scratch my back?

I sadly don't have plans yet. I stumbled on these, but are for a electrobird.
There must be a good set available somewere?

By the way, check this very interesting site. Specialy the photo archive!

Both Saetta's are flying with the same engine. ASP 120 and a Graupner 3-blade 12 x 8.
I think a 15 x 8 2-blade is the better way to fly this.

I think flaps are a good thing for this model, but it's difficult to change the wing for retracts
and flaps.
Saito 100 is big enough, the ASP has not much power.

I have a Saito 170 radial without a model, maybe he will work in the third Saetta
