The Revell Bf-109G-6 when released was a welcomed addition to the 32nd Luftwaffe modeler. The Hasegawa kit was getting more difficult to find and was expensive nonetheless. The Revell kit at a third of the price was a bargain. However, the kit did have some shortcomings. One of the noticeable errors was the oil cooler under the nose. The kit was just not right. The sides were too vertical and that threw off the angles of the whole assembly.
The Quickboost piece is a single part with a minor pour block on the front of the cooler. You will have to clean out the front opening. This is nothing too difficult. Then to that piece you’ll have to add the kit exhaust flap. The part is a direct replacement for the kit part. The shape is spot on and looks significantly better than the kit part.
This set will require some patience but nothing that a modeler with a few resin pieces under his belt couldn’t handle.
Highly recommended
