Military aircraft vol.56

Subject: Horten (Gotha) Go229
Scale: 1/48
Manufacturer: Dragon
History:The Horten H.IXRLM designation Ho 229 (often called Gotha Go 229 due to the identity of the chosen manufacturer of the aircraft) was a German prototype fighter/bomber designed by Reimar and Walter Horten and built by Gothaer Waggonfabrik late in World War II. It was the first pure flying wing powered by jet engines.
It was given the personal approval of German Luftwaffen Reichsmarschall Hermann Göring, and was the only aircraft to come close to meeting his "3×1000" performance requirements, namely to carry 1,000 kilograms (2,200 lb) of bombs a distance of 1,000 kilometres (620 mi) with a speed of 1,000 kilometres per hour (620 mph). Its ceiling was 15,000 metres (49,000 ft).
Comments: Injection molded, with photo-etched parts, water slide decals.
            This is my Horten IX from Dragon in 1/48 scale. I tried to build the third prototype, Ho229 V3, as it might have looked during it´s construction. The wings were left in natural wood color, still unpainted. Other parts were painted in primer and a few, specially at the main body, were painted RLM81 grun. This was common during airplane construction since parts came from different small contractors.
            The model was built out of the box. I scribed a few panel lines along the wings according to monogram´s Luftwaffe Jet Aircraft book. The model was painted with Tamiya acrilics and the wood effect was done with artist´s oils. The natural metal parts were done with alclad 2.   
Here are some pictures of the most challenging part of the painting process: the wood effect:
1) The scribing of the panel lines:


2) The various shades of wood color came from the Tamiya acrilics range:


3) The wood effect: it was done with artist´s oils and a wide and firm brush. The oil color was randomly applied on the wing surface and brushed to the side with the wide brush dipped in just a little bit of solvent.


Now, the completed model:

Aircraft Walkaround vol.20: Republic RF84F and F84F

Subject: Republic RF84F Thunderflash and F84F Thunderstreak
Location:  Flugausstellung L.+P. Junior, Germany, 2012.
Comments:The Republic F-84 Thunderjet was an American turbojet fighter-bomber aircraft. Originating as a 1944 United States Army Air Forces (USAAF) proposal for a "day fighter", the F-84 flew in 1946. Although it entered service in 1947, the Thunderjet was plagued by many structural and engine problems that a 1948 U.S. Air Force review declared it unable to execute any aspect of its intended mission and considered canceling the program. The aircraft was not considered fully operational until the 1949 F-84D model and the design matured only with the definitive F-84G introduced in 1951. In 1954, the straight-wing Thunderjet was joined by the swept-wing F-84F Thunderstreak fighter and RF-84F Thunderflash photo reconnaissance aircraft.
      In 1949, Republic created a swept wing version of the F-84 hoping to bring performance to the F-86 level. The last production F-84E was fitted with a swept tail, a new wing with 38.5 degrees of leading edge sweep and 3.5 degrees of anhedral, and a J35-A-25 engine producing 5,300 pound-force (23.58 kN) of thrust. The aircraft was designated XF-96A. It flew on 3 June 1950 with Otto P. Haas at the controls. Although the airplane was capable of 602 knots (693 mph, 1,115 km/h), the performance gain over the F-84E was considered minor. Nonetheless, it was ordered into production in July 1950 as the F-84F Thunderstreak. The F-84 designation was retained because the fighter was expected to be a low-cost improvement of the straight-wing Thunderjet with over 55 percent commonality in tooling.
    In the meantime, the USAF, hoping for improved high-altitude performance from a more powerful engine, arranged for the British Armstrong Siddeley Sapphire turbojet engine to be built in the United States as the Wright J65. To accommodate the larger engine, YF-84Fs with a British-built Sapphire as well as production F-84Fs with the J65 had a vertically stretched fuselage, with the air intake attaining an oval cross-section. Production delays with the F-84F forced USAF to order a number of straight-wing F-84Gs as an interim measure.

Thank you all! 

Kit review vol.7: Atomic Cannon U.S. Army 280mm Gun with 50t Transporters



Subject: Atomic Cannon U.S. Army 280mm Gun with 50t Transporters.
Scale: 1/32
Manufacturer: Revell (Renwall molds)
Comments: Injection molded, with over 300 parts. No clear parts, waterslide decals.
      This is the famous Atomic Cannon, also known as Atomic Annie, released by Renwall models around the 1950´s. Inside the large box, you will find parts to build the 280mm gun and both front and rear transport vehicles designed to carry the large weapon to the battlefield. The molds were old, but fit is nice. Overall detail represents the top technology of the 50´s but it is not up to today´s standarts. However they have survived in quite a good shape, with minimum flesh. With some extra work, this will turn intgo a great model. The figures included were of no use. So if you want to build a diorama, you will need some new ones. Decals were for the standart markings of the weapon. Bellow, you have pictures of the sprues, decals and a few details of the instructions. I got my Atomic Cannon at Squadron Mail Order. The kit was on sale for just under US$28,00. Getting it all over the world to Brazil cost me US$55,00, almost twice the kit, but was worth the investment. It is a classic kit!

History: The M65 Atomic Cannon, often called Atomic Annie, was a towed artillery piece built by the United States and capable of firing a nuclear device. It was developed in the early 1950s, at the beginning of the Cold War, and fielded by 1953 in Europe and Korea.
      Picatinny Arsenal was tasked to create a nuclear capable artillery piece in 1949. Robert Schwartz, the engineer who created the preliminary designs, essentially scaled up the 240mm shell (then the maximum in the arsenal) and used the German K5 railroad gun as a point of departure for the carriage (The name "Atomic Annie" likely derives from the nickname "Anzio Annie" given to a German K5 gun which was employed against the American landings in Italy). The design was approved by the Pentagon, largely through the intervention of Samuel Feltman, Chief of the Ballistics Section of the Ordnance Department’s Research and Development Division. A three-year developmental effort was begun. The project proceeded quickly enough to produce a demonstration model to participate in Dwight Eisenhower's inaugural parade in January 1953.
      The cannon was transported by two specially designed tractors, both capable of independent steering in the manner of some extra-long fire engines. Each of the tractors was rated at 375 hp, and the somewhat awkward combination could achieve speeds of 35 miles an hour and negotiate turns on 28 ft wide, paved or packed roads. The artillery piece could be unlimbered in 15 minutes and then returned to traveling configuration in 15 minutes more.
     On May 25, 1953 at 8:30am local time, the Atomic Cannon was tested at Nevada Test Site (specifically Frenchman Flat) as part of the Upshot-Knothole series of nuclear tests. The test—codenamed Grable--was attended by then Chairman of the Joint Chiefs of Staff Adm. Arthur W. Radford and Secretary of Defense Charles Erwin Wilson. It resulted in the successful detonation of a 15 kt shell (warhead W9) at a range of 7 miles. This was the first nuclear shell to be fired from a cannon. 
     After the successful test, there were at least 20 of the cannons manufactured at Watervliet and Watertown Arsenals, at a cost of $800,000 each. They were deployed overseas to Europe and Korea, often continuously shifted around to avoid being detected and targeted by opposing forces. Due to the size of the apparatus, their limited range, the development of nuclear shells compatible with existing artillery pieces (the W48 for the 155mm and the W33 for the 203mm), and the development of rocket and missile based nuclear artillery, the M65 was effectively obsolete soon after it was deployed. However, it remained a prestige weapon and was not retired until 1963.



Bellow you have the kit´s sprues, some samples of the instructions and decals:
Bellow, two sets of identical sprues


The figures i mentioned at the text:

Fit of some parts is very good as with the two halfs of the tires:


Some nice details on other small parts:







The instructions:




 The machine gunring does not have an opening on the cabin top. Some details will need extra work!
