Another quick upgrade for the Airfix Wildcat are these two exhausts. They are direct replacements for the kit parts and have very thin walls. While you can paint the insides black I think for the best effect you would still want to drill out the exhaust hole from the engine. Just be careful on how you hold them, the resin is that thin.
No instructions are provided as they are a direct replacement for the kit part.
Thanks to Aires and IPMS/USA for the review kit.
