Thanks for the responses.  At least we know it still exists and will hopefully be coughed up by the postal system soon.

Latest Aeromodeller is in at my local model shop, but Traplet closed the doors and called in the receiver yesterday according to my contact.

Mine just arrived, after a ritual soaking by the postman.

That looks great. Really nice printed tissue.

Are you going to make the canopy from a flat sheet?

Maybe paranoia is setting in as a result of the news about Traplet but my copy of this month's Aeromodeller is unusually late arriving.  I've checked with other subscribers in our club and they haven't received theirs either.  I know Andrew has stepped aside for a while. Does anyone have any inside information?

Thanks Mike and Andy.

I will have to put my patient hat on and build a jig.

Mike your SRE looks awesome!

This is the Saetta, a Macchi design, developed into the MC.202 Folgore and 205 Veltro. You're thinking of the Fiat G.50, which is very similar.

Your plastic kit could have been either though: Airfix for the G.50 or Revell for the MC.200.

Nice subject Marco! Will be following

Title says it all, I suppose... The August 1974 issue of Model Airplane News featured a plan for a peanut scale Luton Minor by Hank Nixon. It was a center spread pull-out as I recall. Not particularly accurate, but a real charmer none the less. This model (and plan) made a lasting impression on me as a ten year old kid when I saw it in the magazine. About time I finally built one!

Would any of you fine folks have a copy of this plan?

Cheers,

Mike

Is this a Fiat design? I think I may have built a small plastic model of this as a kid. I remember the open cockpit.

Mike...amazing skill with the tissue application, not discounting the great craftsmanship on the build and instrument panel.  Outstanding!

The theoretical AOA is that line from T.E to the centre of the L.E curvature but I have never been persuaded that this works in practice on small wings flying slowly no doubt due to the reynolds numbers and the fact that the theoretical section only exists at the ribs and the mean wing section is somewhat different if you take into account tissue sag.  To put it another way I think that relying on theoretical AOA based on a philips entry is doubtful with this construction and and airspeed

I think the air foil has reduced the stall angle and max. lift and has too much drag. It looks like the original designer was influenced by full size air foils.

I'm sure the contest flyers of the time such as Korda and Lanzo already knew this and the proof is in the performance of their models as compared to that of some of these sport flyers.

My thoughts exactly John, some of these JA designs are cool because they have a nice scale-like look, not because they were built as contest rubber flyers, like the Hurricane, which has a nice undercambered rib by the way and is an impressive flyer! The SS seems to be very sensitive to small changes in trim and just doesn't having the nice gliding airfoil that even a flat bottom rib has (like the PA). So of course a rubber flyer would never use this type of rib, but it does have a cool scale look!

That's a good point about the ribs Larry.

After going back through your photos and checking I think they are a large part of the problem. They are in my opinion too thick for the low speeds and Reynold's numbers this model would be operating at - even for RC models.

I wouldn't mind betting that the model would perform a lot better with the same camber and half or less of the thickness shown. However that would mean another wing.

 Grin  the other wing is getting built and i am starting to prepare the fuselage to get wings.  first i put a plate to receive the wing plate then i will build the wing plate from 1/8 sheet to mate with the wing root. spars will go thru to join with formers making a solid connection i hope,

I used cheap Styrofoam board to make wing jigs for my last biplane - see pics here:  http://www.hippocketaeronautics.com/hpa_forum/index.php?topic=21454.msg204715#msg204715.

Thanks for the kind remarks.  Smiley

...

The holey centre spar web looks neat.
...


I enlarged them slightly with a Permagrit file.

Um... perhaps I shouldn't have admitted that because I suspect Kit Scale judges do occasionally look in to see what's going on, but I've racked up a fair number of penalty points already so a few more won't make much difference...  Smiley

...

Andrew did a nice job on the design of this model.


He did indeed.

Thats looks really nicely finished, esp the nose infill and the shape of the exhausts, the weight seems reasonable. How are you going to do the upper wing fillets?

Malc.

I worry about the weight because Jon's Pinko PR Spitfire had lighter components and still required a significant amount of nose weight; on the other hand, I suppose that my tissue is probably a bit lighter than the pink stuff that Jon used. I'm going to do the upper wing fillets exactly as it says on the plan - paper pattern, covered with tissue, curved to fit and stuck in place - looks as though it ought to work OK.

I normally attach biplane wings as described on here:

(very useful site...)

(nice build, BTW)

Love that airplane Marco.
Cant go wrong with a desert camo.
Looking forward to progress

Hi Crabby,

No haven't yet used your dad's floats; too afraid I'd break them with my less than stellar trimming skills.  I use them as an example when I try to make copies.

Don


Don, your Stallion looks like it would ROW all day long....let's get her wet! I think you will need a sub-rudder and rudders on at least one float, (says the guy who never tried it)

Looks like a red Lanzo Puss Moth?
Yeah pic#1 reply #12 I'd buy that!
