Scratchbuilt 1/72 Nungesser Hydravion

-This is the building article, the completed model can be seen here:

Back to weird, as it should be.

After some wandering around toying with more plane-like subjects, the usual stints and dabbling into related fields (the cars and buses), is back to the roots time.
For years all those who know me had to endure the shower of esoteric stuff upon their modeling heads. I am sure they miss it, so here it is some more of that.
There is beauty and beauty. There is the predictable, boring, repetitive beauty of the known types that have been modeling far beyond saturation, and there is the gourmet, secret pleasure of the beauty hidden in more selective subject choices. I'll just say to you, as an example of what I mean: Farman Jabiru. A subject one day I hope to honor.
Meanwhile today we gather to celebrate an even more arcane type: a winged creature born in darkness and shrouded in secrecy, but coming now to light in all its splendor, the Nungesser Hydravion.
How strange in so many ways is this apparatus, regarding not only its appearance but also its provenance. Reportedly it was created by or (more likely) made for Nungesser, the famous French pilot -although no other sources than the Gallica archives state so-. Design-wise, is of the canard type; they probably thought that if a duck floats, then a "canard" -duck, in French- configuration would be optimal (or at least safer) for a flying boat. Interestingly enough, is a tractor canard, that is, the engine "pulls" from the front of the "fuselage" and therefore does not push from behind as in other canard designs. No details other than the ones that can be surmised from the very few photos are found or provided. Nevertheless, this extremely attractive weird ugly duckling surely deserves to come to life in model form.
As usual, I started by having to draw the plans for it, very carefully studying the photos, comparing, and tracing, and erasing, and re-tracing, etc.
This bird was all wood-covered, save a panel in the upper front of the "fuselage" that looks like formed metal sheet. Window-doors with three hinges each are seen in both sides, along with profuse windowing ahead and after them. The radial engine is fixed, as one can safely assume from the exhausts connected to the cylinders and gracefully curving out and back on both sides. I had the file on this subject for years now, waiting for the odd chance that more material will be eventually revealed, and although that was the case for many of my files that sat quietly in the dark, in this case the mystery remains.

Work begins as usual with styrene sheet and strips:
 The "float" and the two "horns" that will hold the canard stab are produced:
 Flying surfaces:
 The float has a fin:
 For the cockpit/cabin, given its multiple windows/doors, I decided to go with clear sheet that can be masked and then painted, avoiding the necessity of craving the windows and add clear panes:
 Floor and roof are cut, and strips are added to the clear bit:
 The standard interior is devised:
 Parts fabricated
 And ready to paint:
 Dry fit:
Compared to parallel build, Farman 200:
 The roof and floor already glued:
 The streamlined top is carved from basswood:
 Dry-fitting and ready to vacuform a part:
The top is vacuformed:
 Tried out:
 The wood prop is carved, at the same time that a spare one:


The top of the gondola is carved to allow for the wing. The wing has been given a slight dihedral according to photos:
 The front "fork" is glued, the engine and prop are almost completed. The engine was reworked from a different model, cylinders chopped, re-arranged and pushrods added at the back. All the parts are kep separated until after painting and "wood" decaling
The prop ready:
All the main parts ready:
main parts are glued and masking ensues:
General view:
Base layer of paint is applied:
More masking and another color (to the left):
The process of applying the home-made "wood" decals begins:
Section by section the model is covered:

 Still to do: add control cables, window frames, add engine, stab, make cradle. Sigh.
The machine is seen in photos on a track, held via dolly, and this was replicated too:

  1. Gabriel: Hi I have been following your work for a while. C an you tell me the best adhesive for vacuform kits?

  2. I use Model Master liquid cement (the one with the needle dispenser) when the parts are thick enough and also Plastruct Bondene and Tenax 7R when the parts are thin. As you know, the cement has to be applied sparingly especially on thin vacuformed parts.
    Hope this helps.

  3. Hello,
    your Nungesser Hydravion look's "terrific", I like.

    how do you do "home-made "wood" decals" ?
