We are back with another test. The long-awaited Curtiss H-16, opening the Murphs Models seaplane season. It is a complex model and will certainly require meticulous work in the construction and installation of the rigging.

The Curtiss H-16, one of the final descendants of the family of flying boats that began with the Curtiss "America." The H-16 was a definitive design when it entered service with the U.S. Navy and RAF in 1917. (Felixstowe F5) Over 300 of these big birds were produced to hunt German seaplanes and submarines. The H12/16 family served as the basis for many postwar designs, including the Japanese H1N1 flying boats and the F5 family designed by Curtiss at the very end of the Great War.

The model has 9 pages of parts, one of instructions and another with a biplane assembly jig, something that has accompanied Aaron's models for some time now.

The model is in Letter format and its original scale is 1/45, it has formers for the hull, detailed cockpit, control horns on the wing surfaces and extremely detailed liberty engines, which provides an interesting challenge, in addition to the construction itself which involves a boat with wings and a forest of struts and cables.
Updates coming soon.

I would find that plane a challenge in plastic or resin let alone paper and card............
-
Many thanks, is a big challenge, like my Caproni Ca 3. 8)
-
We started building the model by organizing the assembly and studying a better sequence of steps. We cut some pieces, separated sets, laminated the formers and assembled the construction jig on cardboard.

We will certainly start by building the wings and the internal lintels, moving on to the other moving surfaces of the tail, first, the engines will be built separately and attached practically at the end of construction.

Cool subject, gomidefilho!
I like the Curtiss flying boats. Being raised bayside in Coronado, I used to watch the Coast Guard's Hu-16s land on the water and taxi up the ramp at CGAS San Diego. There was a steak and seafood restaurant on Orange Avenue that had all sorts of photos of Curtiss, Hall, and Grumman flying boats and seeing a model of one conjures good memories of childhood.
-
Oh! I can't wait to see what you do with this one. It'll be amazing. Based on my previous builds, Aaron's models go together well.
I'll be watching for sure!
Dan

Thanks my friends! I'm glad with your kind words! :D

Well friends, after a short period of absence, we return with the construction of H-16. We started building the wings, which have a prominent wingspan but with a thin chord. I made the internal spars, the tail surfaces, cockpit elements and the wing tip float, which despite being a simple piece I found highly complex to build due to the double curvature.

At the moment, the only thing I haven't done is hollow out the control wheel spokes, but in the original scale it's more than recommended. Today I will build the top wing and start building the fuselage, which is complex because it involves two distinct stages: the keel with its airfoil/hydrofoil and the upper structure of the fuselage.
-
A great start. This type of modelling looks very challenging to me.....

Thanks again NigelR! More to show today. ;)

We return to work on the H16, starting with the hull/fuselage. I have built many Aaron models (I confess I have lost count) and I can say that this fuselage involves some interesting challenges, as it has three distinct layers: keel, airfoil and fuselage, with very interesting and complex transitions.

First we build the keel by adhering its formers, taking care with those that are steps. Afterwards we adhered layer by layer of the airfoil.

With everything dry, we started building the fuselage, starting with the cockpit section and then moving on to the others. It was a slow construction, because the pieces were glued only at the tops. It literally took the whole of Saturday and part of Sunday late afternoon to glue everything together, because the top gluing was done in pieces, waiting for each glued stage to dry before starting another. In some places, small pieces of thick cardboard were used to anchor the pieces, preventing them from moving outside the gluing area.

The nose part is laborious and difficult to glue, later on, the next one will have the experience of gluing it to the fuselage before fixing it to the front portion of the airfoil.

Here we have the fuselage practically complete, only missing the cockpit elements, although it was laborious I liked the results and had a lot of fun. I think that in the original scale (1/45) it does not present great difficulties of construction as long as the modeler is attentive. The cockpit in the original scale offers to the group that likes to improve the models a nice space to insert a detailed interior.
Next steps: general construction of the aircraft and testing of the assembly jig. ;)
-
Well friends! We return again with the test build of the Curtiss H16. In this section we build the cockpit elements, and the general construction of the plane and the wings, without any major problems at this stage, draws attention to the wingspan and slender wing.

The jig works very well, at least in the arrangement of the fuselage/lower wing assembly. Now let's start laminating the struts and the biggest challenge begins.

That is coming together very nicely.....and quickly! Well done so far.
-
It seems like quite a challenge scaling down a large model - but so far it's all looking pretty good! I'm interested to see the next update.
-
NigelR, KiwiZac thank you very much! It's been an interesting challenge.
-
The work is being developed slowly but steadily, we built the beach maneuver car and built the struts with the help of the jig and using plans and photos to determine the positions of the struts.

The techniques are the same as always, we use contact glue to anchor the struts and then apply a layer of CA glue to fix and weld the structures between the wings, always checking the alignment.

This afternoon I completed the construction of the tail struts, they still need treatment and painting. Now I dedicate myself to engines that are quite detailed.

Lovely so far! You make it look so darn easy...Dan
-
Interesting to see this project come together.
No chance to assemble this without a jig, so it is nice to have one included.
Have a few of his kits, but do not like his strange scales "to fit the sheet".
Regards Joachim

Very impressive work so far. But those engines look very challenging......

Yes the jig is fundamental to the general construction of the model, even though the struts are aligned at 90? in relation to the plane of the wings.
The designer of these models, Aaron Murphy, has a predilection for large scales, but doesn't care much about standardizing the scales. We ended up having to discover them and reduce or enlarge them to standard hobby scales.
Thanks Joachim! :D

After a few days away due to problems with family that fortunately were resolved, we returned with the Curtiss H-16, at the moment we are building the engine with its gondola and struts, due to the amount of parts, it is by far the most complex job so far, ( took up a good part of this Friday - today is a holiday in Brazil). Now we will go to the other side, to finish this step.

Indeed,becuase the small side of pieces (many are a pain for folding and forming) and samll area of gluing, takemany hours between gluing and dry subsets. :)

With Saturday being the wife's birthday, I had little time to model. But I started to build the elements of the second engine. It is important that the struts are already built together with the main parts of the engine, this makes it easier to complete the stage.

I worked on the second engine of the H-16 yesterday (it was a national holiday in Brazil - Black Consciousness Day). I took advantage and installed the hooks and actuators for the moving surfaces. At this stage the model will have the rigging installed, work that I should start tomorrow and should last throughout the weekend, considering the complexity of the plane.

This weekend I basically worked on rigging the Curtiss H-16, a laborious job that involved a lot of research into the position of all the cables.
(https://i.imgur.com/XKiQNTBl.jpg)
The techniques are the same as those already used in other models, we use monofilament nylon and broom bristles glued with viscous cyanoacrylate glue. We use a transfer caliper to measure the size of the cables to be cut and to position them we use a wide variety of small electronics tweezers.

We started from the inside out in the interplane area, starting with the support cables for the engine struts, then adhering each structural "box" of cables following the references. Aircraft from the First World War did not have hydraulic controls, everything was moved by pulleys, the larger the plane, the more pulleys, hence the complex system of control cables that were installed later, then we installed the longitudinal structural cables of the wings following the references and then After three days, we have 80% of the work completed, and can then move on to the tail cables as well as the tail control cables.

That's looking very impressive with all the rigging added. Nice work all round.

After three days of intense work, and meticulous research trying to find out where each cable fits or is located, I finished the Curtiss H-16, adding this classic plane to my collection.

Although it is laborious (it is certainly not a model for beginners), it is very cool to build, and can provide in its original scale (1/45) a basis for detailing the cockpit and engines (although these are very detailed) .

As a basis for the work, in addition to the Windsock Datafile on the Curtiss H-12 and Felixstowe, I used this excellent book by Aeronaut, which literally exhausts the subject, including dealing with the Curtiss F5L that editor will soon be designing.
(https://i.imgur.com/NBJdajdl.jpg)
Murph's Models should make the model available soon (maybe even today) and I highly recommend it.

EXCELLENT job! Always loved this machine. You did it proud!

Well done, this whole build has looked like a lot of work and the end result is well worth it.

Thank you my friends! Indeed I very proud and like a lot this model! I take a little break, but the next is a Felixstowe F2a, I printed today. :D
