Thank you to Aires-Quickboost and the IPMS Reviewer Corps for the privilege of reviewing this excellent aftermarket resin engine. The replacement engine adds an eye-catching crisp detail in a highly visible part of the Hobby Boss FM-2 kit, which represents the latest tall-tail version of the Wildcat.

The package contains the engine on a single casting plug, molded in medium brownish-gray polyurethane resin. The application is very simple; trim the engine off the plug, clean up, and replace the kit parts. This is nearly a direct drop-in replacement; all you need to do is carefully remove the engine from the plug, trim out the casting webs from the cylinder backs, and modify the new engine to fit the kit engine mount. Be sure to mount the new engine in the correct orientation, since the replacement engine does not have a locating slot. This is not a problem; just ensure that up is up!

The kit engine consists of two part, the gear housing and the cylinders. The QB engine is a single piece, and give the option of adding pushrods. No push rod material is included. However, 0.020-inch diameter plastic rod may be easily glued into sockets molded in the QB engine. The pushrods on the kit engine are solid sheets attached to the cylinders. Adding pushrods to the QB engine creates depth and detail.

I highly recommend this detail engine for the ease-of-use and value for the money. Thank you again to Aires-Quickboost and the IPMS Reviewer Corps for the privilege of reviewing this excellent aftermarket resin engine!
