Designed and 3D printed in-house by MPM Hobbies, this 1:32 scale resin engine upgrade brings exceptional detail to the iconic Pratt & Whitney R-1830 Twin Wasp powerplant. Purpose-built for serious scale modelers who demand more from their builds.
This upgrade is engineered specifically for the Hobby Boss 1:32 kit #83211. The R-1830 Twin Wasp engine powered some of WWII's most iconic aircraft, including the Douglas C-47, DC-3, and Consolidated PBY Catalina — making this upgrade a natural fit for any of those builds.
