The Vought F4U-5N Corsairs were delivered from the factory with four 20mm cannons with installed flash suppressors. Quickboost provides you with a set of Vought F4U-5N 20mm cannon fairings with flash suppressors. Of note is the re-sealable packaging that Quickboost uses that makes the parts easy to review and then stuff back into the package securely. There are no supplied instructions; you simply swap out the Hobby Boss provided plastic parts with the new Quickboost replacements. Although these cannon fairings with flash suppressors could be used on other F4U-5N kits with modification, Quickboost already has a set out for the Hasegawa F4U-5N kit (QB 48 680).
Quickboost has molded the cannon fairings with flash suppressors perfectly in light grey resin with no apparent bubbles. The Quickboost exhausts have no mold seams to sand off along with a hollowed out barrel flash suppressors.
