RWD-9 Spanish Civil War - from RWD-6, scratch

Recommended Posts

Hi,

RWD-6 and RWD-9 are coupled very ofted, however besides general idea thay did not too many common parts. 

RWD-6 was designed fo a competitions "Challenge" in 1932 which she won piloted by Franciszek Żwirko.  More about this machine cane be read here:

https://en.wikipedia.org/wiki/RWD_6 

For next "Challange", in 1934, RWD prepared a new, bigger design RWD-9. Again this machine won contest piloted by Jerzy Bajan, moreover she took also second place piloted by Stanisław Płończyński. More can be read here:

https://en.wikipedia.org/wiki/RWD_9

Whereas RWD-6 was only in phase of prototype the RWD-9 was produced in small series (2 prototype and 8 produced). One of them was sold to Spain and took part in early phase of SCW until was crashed in Autumn 1936.  

 

There is very good monography of RWD-6 and RWD-9 by Andrzej Glass  issued in Poland. There are nice scale drawings and colour profiles as well as many BW photos in this book.

Despite great sucess of RWD-9 there is no model o it on market. In 1/72 there is a model of RWD-6 (currently still produced but the moulds are already very worn).

The RWD-9 was then developed into RWD-13, which has three kits in 1/72 (injected short run by Aster, vacu by Broplan and resin by Ardpol).  Despite some general similarity between RWD 6 and RWD-9 it seems to be better to do conversion from RWD-13 rather then from RWD-6. However of those three only Ardpol is easy available, two others are more difficult to get. 

I decided to do conversion using two kits of RWD-6 a base. One kit was complete the second was mainly only the fuselage. Wings I have used for scratch conversion of Nimrod from Fury... (If somone is intersting it is here: )

Going back to RWD-9. I started with fuselage. I cut two fuselages and made a 4-person cabine,

45261609412_195d589f6d_b.jpg

31436162098_6c816de61b_b.jpg

 

I glued windows and secured them with Tamiya tape

45261611052_2fe765c39d_b.jpg

 

Of course inside was done as well

30370817337_5535520e5e_b.jpg

 

The wings of RWD-9 are about 5 mm each longer in scale (and heve different flaps chord) with genaral the same chord. I glued them (tops and bottoms) shifted by this 5 mm and

the gaps filled with Tamiya resin putty (since normal putty has too large contraction or shrinking  while drying) 

Here they are on the drawings of RWD-6

31436163418_b807d9e0a7_b.jpg

And here on drawings of RWD-9

45309971421_3c5dfdeabf_b.jpg

 

Since all pannels and control surfaces are different I had to sand out all structure

 

 

Going back to RWD-9 in Spain. The bottom profile (based on photo showes her in pre-war colours

There are some profiles ahowing as she could look during SCW:

75_1.jpg

75_1_b1.jpg

 

However the rudder of RWD-9 survived, it looks like that

 

09-ster1.jpg

on a a bit other side take: 

maxresdefault.jpg

It is clear that bottom of rudder stayed red, so very likely bottom of whole fuselage also retained original red colour!

Likely the machine was not re-painted also on wings from bottom side, and I think this will be how I will finish it.

The prop also survived (and is black)

To be continued

Hi

The canopy I glued from small parts, each window as separate one piece

44457219535_6a5be27f49_b.jpg

 

The left and right  windows from windscreen were rounded, not flat like others were. I cut it from plastic wine "glass"

43554950640_4d0cf3d4bb_b.jpg

 

The top window is taken from RWD 6, all otheres are cut from plastic element of Gillette box of shave blades :) .

 

The tailplane is a bit too narrow, so I glued extension in control surface and added some putty on ot...

The nine cylider engine Walter Bora had 110 cm diameter in original, so it about 15 mm  in scale. I had to enlarge Towdend ring

43554952720_9c8a36c8dd_b.jpg

 

The engine itself will be a resin copy of engine from Praga E39 by RS.

 

I started to scribe surfaces of wings

J-W, this shows that the art of proper, old fashioned model making is alive and well, and safe in your hands! Absolutely brilliant work.

Coming on nicely J-W, and yet another make I hadn't heard of. It's nice to be able to learn as well as see great modeling!

Many thanks Gents for warm words at begining :)

The 9 cylinder engine Walter Bora will be represented by weaker Walter Gema from RS Praga e39. I am copying it in resin, to have for both machines, It has correct diameter of 15 mm 44499830955_aa4e5cb102_b.jpg

and canopy (sanded with 600, 2000 and polished with cotton cloth)

Some sunk spots on rear part of top window I have filled with trancparent resin glue,

RWD-9 had 3 different engines. What I am doing, the Spanish one, had different engine than that one which won Challenge. Especially these had reductor moving axies of prop up, whereas in Spanish one the axis of prop was in central place of engine due to planetary reductor.

I made the resin copy of engine, and started to work on rotable prop assembly.

I scaled down to 1/72 large plans publisged by Wiesław Schier in his well known to all older Polish modellers book

The delicate and rised ribs on flaps and ailerons I tried to do as rised borfers of masked by tape surfaces.

I masekd them

Hi,

The bottom of wings - I added fairings of flaps and ailerons mechanisms:

43879821140_ea07914ed9_b.jpg

 

I realized that fin was too short, so I removed it and make it taller by about 1.5 mm

 

43879822250_4c05c90780_b.jpg

 

I glued wings with fuselage

31825264498_7ac9929201_b.jpg

 

31825263518_3947f2b950_b.jpg

 

And struts supporting wings:

As you see I painted very diluted first layer....

Tony, many thanks!  I do hope it will turn out not bad. I did some more work today so I will soon post current state .

 

I have still doubta on true look of this machine during SCW.  As I mentioned already I have different oponion about the camo as presented on some colour profiles . The photo from SCW period does not exists. The hypothetical profiles showes green mottles on ochra with light blue undersurfaces but since on the rudder some areas still are in original alu dope/purple red livery (area with with inscription "RWD" and red bottom of rudder) I think that she was comouflaged hastitly just by spraying mottles on pre war livery.

09-ster1.jpg&key=74e821631f97d0bf627b807

maxresdefault.jpg&key=60758f834517f087f8

I am not sure if the mottles were only green and ochra is just a thin green layer appearence or they are two colours mottles.

 

The Miles  Speed Six here (former G-ACTE) was wearing such mottle camo from which British registation was still noticable

Any opinion or support on that?

Hi Jerzy....

Two RWD9s where actually purchased by the Aviación Militar back in 1935. Original polish reg were SP-DRA and SP-DRB, one of them being the later EM-W46 you can see in that pic. That very plane was lost in an accident later in october, 10th, 1936, at Limoux, France. I don't think she even sported any camouflage.....who knows the other plane, no record, pic or tale exists about it....

EM-W46 was painted in a very colourful scheme of aluminium enamel over red, and an undersized republican tricoloured flag in the rudder.

According to J. Miranda drawings, it showed republican cocardes at some point, wich doesn't make sense at all for it didn't last long enough before suffering the accident.

11206187.jpg

 

11206235.jpg

 

 

And according to some sources, the second example could have had sported this camouflage during her wartime service...

Hi Artie,

Many thanks for your input. I was wondering of anything more is known in Spain about this RWD-9 which was there fairly before the outbreak of war. If you look at the existing rudder of RWD-9 in Spain

09-ster1.jpg&key=74e821631f97d0bf627b807

You see that some camo IS APPLIED at least in form of green spatches.  I think, that above photo suggests that machine was hastitly painted like NiD 52

75_3.jpg

The silver (alu dope) is a bit yellowed as result of cellon aging perhaps. I do not think at the moment that actually mottles are also in ochra colour - only dark green over original red/alu...

Best regards

J-W

I'd suggest a light "mist" of green blotches over the aluminium paint, as you say. Nothing can be assured for sure, so it's up to you to decide wich colour scheme depict. One thing is for sure, and that's just my personal opinion: the red/aluminium scheme is quite colourful and attractive, so I'd keep the camouflage scheme for another plane, there're plenty of them to paint blotches on, but just this one to depict such a beautiful deco. Painting those combined colours letters is a challeng in itself.....go for it...!!!

Cheers....

Artie, at the short movie on YT 

at 2:39 the photo print is shown on which the roundel under the wing is clearly seen!

Hi

I am doing painting in original order - so first before war livery of red/silver and then patches.
