The F4U-5 Corsair was a 1945 design modification first flown in mid-December 1945. It was intended to increase the overall performance, incorporate pilots' suggestions, and featured a more powerful Pratt and Whitney R-2800-32(E) engine with a two-stage supercharger rated at a maximum of 2,850 hp. Other improvements included automatic blower controls, cowl flaps, intercooler doors and oil cooler for the engine, spring tabs for the elevators and rudder, a completely modernized cockpit, a completely retractable tail wheel, and heated cannon bays and pitot head. The cowling was lowered two degrees to help with forward visibility, but perhaps most striking, it was the first variant to feature all-metal wings
The Resin Parts
Injected-molded plastic kits do have some limitations when forming small details. Often times these details may not replicate the parts exactly, have difficult to remove mold lines, or may be fragile.
