The AN-2 “"Annushka" (NATO designation “Colt”) is a throwback from a very earlier age as a rugged biplane used in a STOVL role. The Hobby Boss kit is a nice replica of this plane, yet there are some details that require improvement. Hobby boss provides the option of having the cowl flaps open or closed. Quickboost offers a set of replacement cowling flaps in the open position which are much thinner and have slightly more detail; they are intended to replace kit parts – E49, E50, E53 and E54.

These parts are not quite a drop in fit and required me to clean up the opening in the cowl where the flaps fit; this is due to the accurately molded side pieces of the flaps. The cowl openings are tapered and needed to be squared in thickness to allow the flaps to fit. I ended up enlarging the opening in the longest dimension to achieve a good fit. I used gap filling CA to glue the flaps in position, the slow set allowing me time to work the flaps into the desired angle.

Overall I found the flaps to be okay, not quite the time saver that I had hoped. Some sanding of the kits parts and a few bits of styrene and I could have just used the kit parts. Still the results looks good and I can recommend this set.
