1/12 Radial Engine

Posted by Paul On April - 28 - 2010

4/28/2023 This is my finished 1/12 scale model of the Wright Cyclone radial engine by Atlantis.  This C9HE model of the Wright Cyclone was first issued in 1959 from Monogram, and was really advanced for a model kit at that time.  It shows it's age today, but still builds into a very nice model.  I had a lot of fun building it and the results to me are very satisfactory.  I weather the engine a little with Tamiya black panel line ink and also painted the engine stand yellow and weratherd that too.  I opted not to include the cut away cylinder showing the piston as I thought it looked a little cheesy.  The ignition cables and two additional pipes are made up of flexible plastic material and will not allow paint to stick to them.  I therefore had to leave them in their original copper color.  I was able to paint the ignition cable fittings silver tho.

Here is some background on the engine:

The Wright R-1820 Cyclone 9 is an American radial engine developed by Curtiss-Wright, widely used on aircraft in the 1930s through 1950s. It was produced under license in France as the Hispano-Suiza 9V or Hispano-Wright 9V, and in the Soviet Union as the Shvetsov M-25.

Design and development

The R-1820 Cyclone 9 represented a further development of the Wright P-2 engine dating back to 1925. Featuring a greater displacement and a host of improvements, the R-1820 entered production in 1931. The engine remained in production well into the 1950s.

The R-1820 was built under license by Lycoming, Pratt & Whitney Canada, and also, during World War II, by the Studebaker Corporation. The Soviet Union had purchased a license for the design, and the Shvetsov OKB was formed to metricate the American specification powerplant for Soviet government-factory production as the M-25, with the R-1820's general design features used by the Shvetsov design bureau for many of their future radials for the Soviet air forces through the 1940s and onwards. In Spain the R-1820 was license-built as the Hispano-Suiza 9V or Hispano-Wright 9V.[2]

The R-1820 was at the heart of many famous aircraft including early Douglas airliners (the prototype DC-1, the DC-2, the first civil versions of the DC-3, and the limited-production DC-5), every wartime example of the Boeing B-17 Flying Fortress and Douglas SBD Dauntless bombers, the early versions of the Polikarpov I-16 fighter (as the M-25), and the Piasecki H-21 helicopter.

The R-1820 also found limited use in armored vehicles. The G-200 variant developed 900 hp (670 kW) at 2,300 rpm and powered the strictly experimental M6 Heavy Tank.

Famo Tank Transporter

BUILDING THE TAMIYA 1/35 FAMO TANK TRANSPORTER

 

As World War II progressed, the vehicles used on the battlefields became larger and larger. When these mammoth machines broke down or became damaged, the task of bringing them back from the front lines was not an easy one. This need was especially felt by the German Wehrmacht, who were fighting on a wide range of battlegrounds: from the scorching desert of N. Africa to the railroad lacking plains of Russia. Bringing damaged vehicles back from these difficult conditions was indispensable to replenishing fighting strength to the army. The German 18 Ton Heavy Half-Track "FAMO" and Tank Transporter Sd.Ah.116 was one of the vehicles that contributed to this task. Including all variations, over 2500 18ton half-tracks were produced by the end of the WWII. One of the major types was the tank recovery half-track, which was a mighty towing vehicle equipped with two rows of seats and a flatbed in back for the storage of equipment such as a draw-bar and spare wire rope. Tool storage compartments were found on each of the outer sides of the flatbed. In addition, the underside of a vehicle was equipped with a winch. Its powerplant was a Maybach HL 108 12-cylinder engine, which put out 270hp. Tank transporting was conducted by either direct towing with a draw bar, or by loading the tank atop a massive trailer. Officially known as "Sd.Ah.116", the Type 116 Trailer connected with the 18ton heavy half track, which allowed for the transportation of 22-23 ton class tanks such as the Pz.Kpfw.III, Pz.Kpfw.IV and other heavy artillery.

 

 

 

 

 

 

 

 

 

On Feb. 19, 2011 I won this model at the Model Expo in Petaluma at their wonderful raffle.This is really an awesome model that I just had to start.When finished it will be over two feet long – actually it comes out to 640 mm or 25.17 inches.I will be posting pictures and comments as time goes on.

 

 

 

 

 

 

2/27/2011 I've done a lot of work on the FAMO itself.  Here you see the basic running gear.  There is still a lot of paint touch up and weathering to do:

 

3/20/2011  I've finished the tracks and installed them.  I dusted them with Tamiya brown and then desert sand then used Tamiya weathering powders to add white to the rubber pads.  The front tires had the seam sanded off then the treads were filled with Tamiya thickened primer.  Then I used q-tips dipped in Tamiya thinner to wipe off the excess primer.  This was followed with a liberal dusting with Tamiya weathering sand powder.  I wiped that off with the dampened q-tips also.  The last pics have some of the upper body works placed on the frame.  I have yet to paint and weather these parts.

 

 

3/21/2011 I've painted the upper body works…

 

 

 

 

3/29/2011 I have decided to change the overall color of the body from German Grey to the camo tri color of sand, green and brown.  I have found that the German grey is really dark and the details of the model are harder to see.  Plus that fact that the camo version was a lot more prevalent I believe.  I am painting the tank transporter as if it had an in-field camo job done with spray guns, and the FAMO crew compartment was left in the German gray color as it would have been just too time consuming to mask off and paint in the field.  I also am not repainting the underside as they would have been left as the factory color.  This color scheme will lend itself to more weathering possibilities too.

 

3/31/2011 I've done a little more – all that's really left on the FAMO itself now is adding misc parts and loads….

5/1/2011 I've done a lot on the fore and aft trucks and have just started the trailer framework.  Below are some pictures of all of the parts posed as they would be as finished:

 

 

5/22/2011

I've finished off the trailer and painted the parts of it.  I still have to attach the rubber tires and do the weathering.

 

 

 

6/6/2011

I'm almost done – ha ha.  The tires are now on and I've just added a canvas cover made from tissue dipped in white glue diluted with water.  I've also added some cargo for the famo in the form of 5 fuel drums and a few jerry cans.  The boxes are actually tank ammo boxes but I think they look good in there.  I've also added the decals and given the whole thing a light dusting of sand.  Now to the pics…

After almost four months the FAMO tank transporter is finished!  Here we have the transporter with a captured American Sherman tank.  I still have a few items to add – a bucket and hitch pin along with a few items for the storage drawers in the FAMO.  Please excuse the background items.  I no longer have my photo booth.  Someday I'll have a much better setup for photos – until then….
