Werner's Wings has released a 5-piece resin set to transform the 1/35 Academy AH-1W NTS into the latest version flying in Afghanistan with turned exhausts to provide a lower heat signature. The parts look very clean and the edges are nicely formed with crisp edges.
The set includes the exhaust housing and outlets, 2 inserts for inside the exhaust outlets, the inner engine bulkhead, and a cover for the tail rotor shaft.
It also comes with a detailed instruction sheet showing you how to install the parts.
It requires that you cut part of old exhaust attached to the fuselage and replace it with the resin parts. Also warns about cutting the area around the driveshaft cover, recommends that you cut the exhaust area first then measure area for the driveshaft cover.
Because the parts have some weight to them you will have to drill out some of the resin from the front of the exhaust. This will help balance the aircraft so it sits correctly.
