Quickboost provides you with a F4U-5 engine reductor, distributor covers, and engine pump. 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 supplied instructions note the swap out of the kit provided plastic parts with the new Quickboost replacements. One part, the magneto is not used with the F4U-5’s R-2800-32W Series E engine and appears to be a carryover for a F4U-4B R-2800 engine (QB 48 045). The F4U-5’s R-2800-32W Series E engine was a fairly unique engine and was not used in any other aircraft.
Quickboost has molded the parts perfectly in light grey resin with no apparent bubbles. The Quickboost exhausts provide you with no mold seams to sand off.
