For combat RC enthusiasts!
Set contains two (2) turrets: one (1) twin 8"/55 turret and one (1) triple 8"/55 turret. Two sets are required to complete one model.
This design uses the most rugged 3D-printed materials available for good performance for combat RC models. Stong and Flexible Plastic is very economical when compared to other materials, is completely waterproof, lightweight, and resistant to BB fire. It's detail is softer than other material (surface details will print thicker), it is not easily sandable and requires primer and paints intended for nylon. A "Best Detail" version is available separately.

From Wikipedia: "The 8"/55 caliber gun (spoken "eight-inch-fifty-five-caliber") formed the main battery of United States Navyheavy cruisers and two early aircraft carriers. United States naval gun terminology indicates the gun barrel had an internal diameter of 8 inches (203 mm), and the barrel was 55 calibers long (barrel length is 8 inch × 55 = 440 inches or 11 meters).
"Mark 9: These built-up guns weighed about 30 tons including a liner, tube, jacket, and five hoops. A down-swingWelin breech block was closed by compressed air from the gas ejector system. Loading with two silk bags each containing 45-pounds (20 kg) of smokeless powder gave a 260-pound (120 kg) projectile a velocity of 2800 feet per second (850 m/s). Range was 31,860 yd (29,130 m) at the maximum elevation of 41 degrees.
"Mark 14: These guns were similar to Mark 9, with the same shell weight and maximum range, with a smaller chamber and rifling twist increased from 1 in 35 to 1 in 25 in a chromium-plated bore."
