Welcome to my personal modeling page. My name is Rogério "Rato" Marczak. I'm a professor of the Mechanical Engineering Department  at UFRGS. Here you'll find stuffs related to my hobby. Everything here is under construction, and I'll be adding new material as time permits. Note that some pages are still written in Portuguese. If you have comments or suggestions, please drop me a line. I'm also associate editor at Large Scale Planes website. If you are at big models, stop by for a visit.

Important notice:
I'm on leave from UFRGS, working at Rutgers University NJ, from August/2009 until July/2010. Therefore there will be an understandable slow down in Antrvm's updates frequency. Although I will not be able to work much on any models, I do plan to add more walkarounds, reviews and galleries during the next months.

Finished models:


Here's I have a couple of very very old models built during my childhood. Still today, they are my best efforts... A kitbashing of two old Airfix Mk.I and Mk.V Spitfires produced the K5054, the Supermarine Spitfire prototype as shown to the public at Martlesham Heath in July/1936. Published by Fine Scale Modeler magazine in issue Feb/2008.
The Sheep's Nest. One of my first models after my return to the hobby. It's a small diorama in 1/144 scale starring the Revell F4U-1D Corsair as it should look in Vella Lavella in 1942. Published by the late Air and Sea Models magazine in 1999.
War Prize is a very battered Tamiya Aichi M6A1-K Nanzan in 1/72, as it was found by the Americans at Kokugijitsusho unit in 1945. This kit was fully riveted using my home-made riveter.
And since we're talking about small scales, here's another small diorama. The Last Days of Pan Am depicts a  Boeing 727-200 parked at Miami Intl. Airport circa 1982. The finger, tarmac and accessories were scratchbuilt. Letzte Gefechte is a small vignette in 1/35 scale depicting a Dragon Püppchen anti-tank gun somewhere in rural Berlin during the last weeks of the war. I used this project to learn how to make realistic trees.
The 1/72 scale diorama Busy Sunday shows an ancient Heller F6F-5 (gasp!) and a scratchbuilt Clark CT-46 tow tractor aboard USS Enterprise during 1944, in preparation for the Battle of Phillippine Sea. Ford at War. The excellent Tamiya F4D Skyray is shown here in 1/72 scale, ready to lunch from USS Franklin D. Roosevelt during the Mediterranean cruise in 1960. This model has scratchbuilt deck and catapult gear.
This is my commemorative display of the 75th anniversary of the first transatlantic flight. It presents a much improved Testors Spirit of St. Louis in 1/72 scale and the William Bros. Wright Whirlwind J-5 engine in 1/8 scale.
Pyccкaя крыса (Russian Rat). The little Hasegawa Polikarpov I-16 in 1/72 seemed a nice kit at a first glance. In the end I added a new cockpit and many details to bring this model to a better standard.

Have you ever made a model of something you actually own? Charlotte the Harlot is a small vignette depicting my dog, Charlotte, in the backyard of our house in the hills. I'd prefer a Ferrari, but...
Dad & Son. The cold-war missile AGM-86B 1/72 kit from the obscure Projekts Model Co. displayed side by side with its dad, the Henschel Hs-293, stolen from the Revell Fw-200 kit. 
Royal Eagle sports heavy scratchbuilding work on the 1/72 Revell (ex-Matchbox) Heinkel He-70K in the Royal Hungarian Air Force livery. This project features scratchbuililt interior, engine and landing gear.
Jäger is my Dragon Jagdpanzer IV A-0 in 1/144 scale. Yep, that small...
Первые шаги (First Moves). The Dragon T-34/76 in 1/72 scale was used as a test bed to improve my limited weathering techniques. I couldn't resist and put it in action during the first months of war in Russia. A fun conversion of the old Heller Fieseler Fi-156 Storch in 1/72 to a tracked configuration...
The venerable Revell Tradewind receives an overhaul and lands on the Pacific Ocean waters. Hunter of the Empire is my rendition of Darth Vader's TIE fighter. Revell kit in 1/72 scale.

An adventure in the world of die-cast. This is the Signature Models Plymouth 1941 staff car conversion. The excellent Tamiya Republic F-84G in 1/72 scale is my excuse to improve my skills on natural metal finishes.
I decided to recycle myself a bit by learning some different techniques building a sail ship. The subject chosen is the Revell Cutty Sark in 1/350 scale. Lots of fun (until the rigging phase comes)...
Here is my first effort in small scale AFV in a long time. The somewhat rare Sd.Kfz.253 half track in 1/72, using the Italeri kit. To be used in a future diorama...

How to turn an Easy Model © into a Difficult Model. This is the Hobby Boss P-40B in 1/72 scale, upgraded to a better standard.
