The iconic Pratt & Whitney (P&W) Company's Radial Engine line is the choice of Authentic Scale for their new line of gasoline radial engines.
Francis Pratt and Amos Whitney found P&W in 1860, to manufacture machine tools and gun making machinery for the Union Army during the American Civil War.
In 1925, Frederick B. Rentschler proposed to P&W the production of his new aircraft engine. This was the beginning of the P&W Aircraft Company, and the first engine was the Wasp, completed in December 1925. It was the beginning of a revolution in American aviation.
Authentic Scale is bringing to market, two scales: 1/5 , and 1/4; of the entire line of P&W radial engines from 3 cylinders (single row) to 28 cylinders (4-rows) with engine displacements from 67 cc up to 900 cc.
With accurate external scale features like the exact fin count, magnet, distributors, oil pump, ignition harness and parts CNC machined from Solid Bar for lightest possible weight, extra long durability and strength. Using materials like steel S4140, Titanium/Nickel/Chromium alloys, aluminum AL7075, Stainless Steel 0.5 mm wall tubing amongst many other features. Unique 2 micro-bearings on EACH rocker arm same as P&W did on their full scale engines.
