The famous "mind the gap" is getting a completely new meaning.

I'm going to hang this in here. Tim is thinking about making LSM T-shirts and he's wondering about possible interest.

She's looking great, nice ,clean work.

The walkways are decals. I removed the clear film with a fresh x-acto blade and chipped them off with a toothpick. The next session was black wash to mimic the fuel spills and puddles. I’m discovering lots of shortcomings , so I’m scribing and riveting as I go. pencil chipping and clear will follow next. Then exhausts stains add lastly small bits like the racks , and fuel lines, barrels and at the end mud splatters and dust.

Water surface looks very convincing, but the submarine tower seems to be modified in an unusual way :). -
Lovely woodwork Chris, I'm admiring people with this kind of talent. Cheers Martin

Pyotr Yakovlevich Ufimtsev Born 8 July 1931 (age 92)[citation needed] Ust-Charyshskaya Pristan, West Siberian Krai, Russian SFSR, Soviet Union Nationality Soviet, Russian Alma mater Odesa State University Known for Stealth technology Physical theory of diffraction Scientific career Fields electrical engineering, physics Institutions Institute of Radio-engineering and Electronics Pyotr (Petr) Yakovlevich Ufimtsev (Russian: Пётр Я́ковлевич Уфи́мцев; born 1931) is a SovietRussian electrical engineer and mathematical physicist, considered the seminal force behind modern stealth aircraft technology. In the 1960s he began developing equations for predicting the reflection of electromagnetic waves from simple two-dimensional and three-dimensional objects.[1] Much of Ufimtsev's work was translated into English, and in the 1970s American Lockheed engineers began to expand upon some of his theories to create the concept of aircraft with reduced radarsignatures.[2] The father of stealth While working in Moscow, Ufimtsev became interested in describing the reflection of electromagnetic waves. He gained permission to publish his research results internationally because they were considered to be of no significant military or economic value.[4] A stealth engineer at Lockheed, Denys Overholser, had read the publication and realized that Ufimtsev had created the mathematical theory and tools to do finite analysis of radar reflection.[5] This discovery inspired and had a role in the design of the first true stealth aircraft, the Lockheed F-117. Northrop also used Ufimtsev's work to program super computers to predict the radar reflection of the B-2 bomber. In the 1960s Ufimtsev began developing a high-frequency asymptotic theory for predicting the scattering of electromagnetic waves from two-dimensional and three-dimensional objects. Among such objects were the finite size bodies of revolution (disk, finite cylinder with flat bases, finite cone, finite paraboloid, spherical segment, finite thin wire). This theory is now well known as the Physical Theory of Diffraction (PTD). The first results of PTD were collected in the book: P. Ya. Ufimtsev, Method of Edge Waves in the Physical Theory of Diffraction, Soviet Radio, Moscow, 1962. In 1971 this book was translated into English with the same title by U.S. Air Force, Foreign Technology Division (National Air and Space Intelligence Center), Wright-Patterson AFB, OH, 1971.[6] Technical Report AD 733203, Defense Technical Information Center of USA, Alexandria VA. This theory played a critical role in the design of American stealth aircraft F-117 and B-2.[7][8][9] See also the Forewords written by K. Mitzner to the books: Ufimtsev, P. Ya. Theory of Edge Diffraction in Electromagnetics, Tech Science Press, Encino, California, 2003. Ufimtsev, P. Ya. Fundamentals of the Physical Theory of Diffraction, Wiley & Sons, Inc., Hoboken, New Jersey, 1st edition 2007 and 2nd edition 2014. In these two books, P. Ya. Ufimtsev presented the further development and application of PTD and its validation by mathematical theory. In particular, a new version of PTD, based on the concept of elementary edge waves, is presented in his book Fundamentals of the Physical Theory of Diffraction (2007, 2014). With appropriate modifications, PTD can be employed for the solution to many practical problems. Among them are the design of microwave antennas, mobile radio communication, construction of acoustic barriers to decrease a noise level, evaluation of radar cross sections for large objects[10] (tanks, ships, missiles, etc.). Dr. Ufimtsev has been affiliated with a number of research and academic institutions, including the Institute of Radio Engineering and Electronics of the USSR Academy of Sciences (Moscow), Moscow Aviation Institute, the University of California (Los Angeles, Irvine) and most recently, the Moscow State University (Russia, 2007) and the University of Siena (Italy, 2008). Currently he is a retiree and a consultant in the field of electromagnetics. Among his honors and awards are the USSR State Prize and the Leroy Randle Grumman Medal.[11] Ufimtsev joined the faculty of the University of California, Los Angeles (UCLA) as a visiting professor of electrical engineering in September 1990.[7] -

Sky King's Songbird: Update: 3/2/24 - SOD .. BINNED
Martinnfb replied to Peterpools's topic in The Great Twins Broup Bluild
I fully understand Peter, It has happened to me so many times. Your desire and excitement gets killed by poorly engineered kit with just way too many issues and obstacles clouding the enjoyment of the build itself. There is always Tamiya quality kits waiting in your stash. Deep breath and this will all go away soon. Sincerely Martin -

I would say grey/brown/red/blue/turquoise/grey blended and defused with sharp outside edge would work. it's merely a reflection on the water surface.
