The Phönix D.III was developed from the Phönix D.II and IIa.. According to Grosz et al., the modifications included a "revised wing planform and a fuselage designed for accessible machine guns mounted at eye level." (page 126). It was also up-engined from a 200 hp to a 230 hp Hiero engine. A hundred were approved for production and were scheduled to be delivered on October 27, 1918, however, there was a delay, and the war's end put a stop to the planned delivery. In 1919 and 1920, the Swedish Army Air Force purchased a total of 20 Phönix D.IIIs; number 947 can be seen at the Swedish Air Force Museum. In a previous edition of Internet Modeler, Bob Pearson provided an in-box review of this kit. My own impressions of this kit were similar to Bob's, that is, the resin parts looked crisp and were finely detailed. Never having built a resin kit before, I was curious as to how things would go.
The first thing I had to decide before starting construction of this kit was the particular aeroplane I wanted to build. The top wing's upper surface contains two fuel tanks and these were only found on the Swedish version of the Phönix D.III; the model would have to built with Swedish markings and would represent a machine from the early post-World War One era. I am more interested in representing World War One era aeroplanes and had seen a picture of J.41 on page 128 of Grosz et al's book. I found the markings to be more colourful and attractive than the Swedish version, in particular, the Austro-Hungarian Crown and Cross marking on the red-and-white striped vertical tail. Unfortunately, this meant I had to remove the upper wing fuel tanks and make the ribs that would have been there otherwise; a more time consuming option, relative to the Swedish version.
My first task was to clean up the wings and fuselage, and remove the smaller parts from their resin wafers. This proved to be quite straightforward; everything cleaned up well. There were no instructions, so I had to study various pictures prior to construction in order to make sure I knew what to do with each part. Except for two small prong-shaped pieces, I worked out which pieces went where. If anyone knows what these two 'extra' pieces represent, I would be glad to hear from them.
Reworking the top wing
After removing the aileron control surfaces, I took the Dremel and the top wing part outdoors, put on my dust mask (resin dust should not be inhaled) and switched on the Dremel. The resin was quite hard and sanding off the wing tanks took some time. After most of the tank was removed with the Dremel, the surface was smoothed off with successively finer grades of sandpaper. The next job was to replace the wing ribs. This was done using the method described by Candice Uhlir in her build-up of the Smer 504K at Hyperscale or Modelling Madness. I placed strips of masking tape either side of where the rib had to go, leaving a very narrow space for the rib. I then brushed on a coat of 'Mr. Surfacer 1000'. This process required a couple of attempts. The first time, I airbrushed the wing and realized I had left too much 'Mr. Surfacer' on the wing, and the ribs I had made were more accentuated than the ones already on the kit. I easily removed the water-based acrylic paint with Q-tips dipped in Windex. The second time, I left only a 'hint' of ribbing and this seemed to work; perhaps my ribs were a little under-stated compared to the kit's this time, but I think it's preferable to err on that side.
Engine, Cockpit and Fuselage
The engine is well detailed but contained some pinholes, which I duly filled with Squadron White putty. I then added some plastic rod to look like pipes to the engine, to try and make it look as much like a Hiero engine as possible. The kit provides six small pieces of resin rod for the port side engine intakes. According to the photographs and diagrams in Grosz et al., the intakes are not lined up parallel to each other; those at the front are angled down lower than those aft, each one being slightly less angled then the one in front of it, giving a sort of 'fanned' effect. I do not know why this was done, possibly it was necessary to bend and redirect them in order to get them to fit around the N-shaped cabane struts, which was certainly a problem I experienced.
I used the materials provided in the kit for the cockpit; namely, the control stick, instrument panel and foot rudder. I added seat belts using strips of lead foil from a wine bottle and buckles from a Tom's Modelworks photoetch interior. I cannot remember which nationality’s interior I used; there is none for Austro-Hungarian aeroplanes. The interior was painted grey, and the frame, seat and instrument panel were painted 'Leather Brown'.
It was my impression that the cockpit area is a little too small since the seat almost touches both sides of the fuselage. Before closing the fuselage, the engine housing area in the front fuselage was sanded out as much as possible using a Dremel. The lower and front parts of the engine were sanded away in order to be able to close the fuselage; none of this surgery was visible when the fuselage was closed. Once glued, the fuselage seams required filling with super glue. Once the glue was sanded down, some faint seam lines remained, and these were filled with some typewriter correction fluid.
Wings, Tail and Struts
The lower wings were then attached to the fuselage. Two small holes were drilled into both the fuselage sides and the inside edge of the wing root. Then small lengths of 28 gauge copper wire were inserted into the holes in the wing root, and the other end of the wires were then inserted into the holes in the fuselage. This gave the wing-fuselage joint a fair amount of strength. A similar method, using the same type gauge of copper wire, was used for the horizontal tail parts.
The aeroplane was painted light grey. Pictures of the aeroplane are inconclusive with regard to colour, however, the example in the Swedish Air Force Museum is a light to mid-grey. The vertical tail was then decaled using decal paper sprayed red and white, and a Crown and Cross decal from Pegasus. This tail part was then glued to the painted fuselage.
I have heard many sad stories about the effect of temperature on resin parts, especially parts that are required to support the model. Never having built a resin kit, I decided to take this to heart and I did not use any of the resin parts for struts or the landing gear legs. The interplane struts were carved from bamboo. This is a fairly straightforward if somewhat time-consuming exercise. You can purchase a packet of bamboo chopsticks that will give a lifetime's supply of strut material. Chop off a small piece a bit longer and thicker than you need. Take a small flat block of wood and tape a piece of double-sided tape to it. Stick the piece of bamboo you chopped off to the tape and start sanding using 220-grit wet/dry sandpaper. Once it is sanded down a bit and smooth, turn it over and do the other side, shaping and smoothing as you sand. Take the 'strut' off the tape, sand it to the right width, use a knife to shorten it to the right length and taper it. Each strut took me about 20 minutes, though I had to throw out a couple that were not right. When you are done, you have real wooden struts. I stained them with wood stain, and then brushed them with a mix of Future and 'Leather brown'. The cabane struts were scratched from .020" plastic rod and tapered at the ends to make them fit the N-shape configuration. The landing gear struts were made from piano wire.
I attached the interplane struts to the upper wing and aligned the struts appropriately. I then glued the struts and upper wing sub-assembly to the lower wing. I gave the exhaust unit atop the upper wing a coat of aluminum paint, followed by a black gouache wash, and then glued it to the wing.
I used some fine piano wire to fashion the exhaust wires from the engine to the top wing. The same material was used for the diagonal struts either side of the horizontal tail. A slightly larger diameter piano wire was used to make the guns inserted either side of the engine.
The J 41 was printed from Microsoft Word onto decal paper using an HP LaserJet IIIp. The black and white cross decals were taken from the spares box, as I attempted to match the size and position of the marking from pictures and profiles in Grosz'’s book..
Conclusion and Recommendations
This is good kit of a less mainstream aeroplane; there are few alternative kits available. My primary criticism is that the upper wing's fuel tanks should be molded separately, which would provide the builder with a straightforward choice of the Swedish or Austro-Hungarian version. As it was, I agonized and procrastinated for months, deciding which version to build, although the building process turned out to be enjoyable. A secondary criticism is that the load bearing parts, such as the struts and landing gear, should not be made from resin due to this material's reaction to changes in temperature. The manufacturers have a choice; they could provide struts made of an alternative material; for example metal, or they could provide a template for the builder to scratch build these parts. I used the resin struts and landing gear as templates but this seems an expensive way to provide a template. Finally, it would be helpful if the kit contained even the most rudimentary instructions.
This was my first resin kit and overall I was highly satisfied. It fits together well, has a fair amount of fine detail and while I would not recommend it for a beginner, it is certainly within the capability of someone who has built two or three biplanes.
