Brengun Models is a scale model and detailing parts manufacturer located in the Czech Republic. Their lines include limited production run multi-media kits and exquisitely detailed photoetch, turned brass, and white metal replacement parts for aircraft in the most commonly produced scales.

Brengun has produced a set of wheels with ribbed tread patterns for any 1/72 scale F4U Corsair. There are no instructions, and any modeler familiar with resin parts will have no issues installing these wheels in lieu of the kit parts. A close-up evaluation of the parts (see photos), indicates a simple cut and replace installation that provides realistic scale-detailed wheels with significantly improved appearance to molded plastic kit parts.

Aleksandar Radić is a Serbian military analyst and author. His primary focus is on the security topics of the West Balkans, the history of the armed forces, the military technology in that region in the 20th Century, and the conflicts that have followed the break-up of Yugoslavia in the period 1991-2001. He has authored a dozen books and hundreds of magazine articles published in the specialized press. Recently, Radic has frequently appeared as a military commentator for major TV stations in Serbia, Montenegro, Bosnia and Herzegovina, and the Republic of Northern Macedonia. This is his second book for Helion's @War series.

This set is designed to provide replacement parts for Italeri’s 1/32 two-seat F-104 kits. As with most of SAC’s landing gear sets, the metal parts are intended to be one-for-one replacements for the kit parts. The centerpiece of the set is a new single piece main gear section including both left and right main gear struts with attached retraction arms and gear door actuators. The set also provides white metal replacements for the hydraulic lines on the main gear struts.

There are four parts to the nose gear – the strut, two retraction arms and what I assume is the nose gear steering unit.

Scale Aircraft Conversions (SAC) manufactures white metal landing gear that is a direct replacement for the kits plastic landing gear. The metal landing gear offer greater strength over the kit parts as well as having most of the mold lines removed. At times, the metal will be bent out of shape but that is easily corrected by bending it back to the correct shape.

This set includes six parts, the two main gear assemblies, bracing arms for the main gear and nose gear with separate bracing arm. All the parts are exact copies of the kit parts with a small amount of mold lines or “flash”. The Main gear still has the kits sprue, with identifying number. Note that the kit part F5 has been moved to the same sprue as part F2. The main gear bracing struts are free from the sprue and not numbered.

This set is designed to be used on Fujimi’s F-14 Tomcat kits. The set consists of 2 resin ramps, replacing the kit’s molded on ramps. The title states that the parts are the ECS (environmental control system) exhaust grills, however, in reality they are the fixed bleed doors which allow excess air to be vented out of the intakes, especially at higher airspeeds when the movable ramps deploy to restrict the airflow down the intakes and keep the air subsonic when it hits the front of the engines.

The parts are exceptionally thin and crisply cast. However, as the bleed doors are molded as part of the upper fuselage on the kit, you will need to break out a razor saw or a new Xacto blade to remove the kit parts and install these replacements. I recommend the removal surgery be completed before you join the upper and lower fuselage halves, but you should hold off on installing the doors until right before painting to avoid damaging them.
