Big Prop Boosts Scalewings SW-51 Mustang

Scalewings has introduced a significant performance enhancement to its popular SW-51 Mustang replica through collaboration with MT-Propeller. The new MTV-22 composite propeller represents 33 percent growth over the previous design, bringing meaningful gains in both capability and authenticity to the 72-percent-scale two-seat aircraft.

The MTV-22 development took more than two years, with MT-Propeller drawing design inspiration directly from the original 1940s Hamilton Standard propeller that powered the North American P-51 Mustang.  MT-Propeller now manufactures full-scale composite propellers for the legendary P-51 and rare P-82 Twin Mustang, while AVIA Propeller, part of the MT group, produces P-51 replacement blades under Hamilton Standard license. That heritage directly informed the MTV-22’s blade shape and tip design.

The new prop increases climb rate by 15 percent—adding 300 feet per minute—while reducing takeoff distance by 15 percent. For owners of existing SW-51s, the MTV-22 represents an attractive upgrade path, with both new and retrofitted aircraft gaining the enhanced performance and improved ramp presence.

ScaleWings CEO Christian von Kessel emphasized the importance of authenticity to replica aircraft owners. “Since MT is now making the Hamilton Standard P-51 prop, it made perfect sense to collaborate with them on a new and improved prop for the SW-51.” Beginning with serial number 052, the MTV-22 is standard equipment. The timing proves fortuitous for ScaleWings, as MOSAIC standards continue driving interest in the category. The company booked more than 20 aircraft in 2025 alone, with 62 total delivered since introduction to the US market just three years ago. For those serious about owning an authentic replica of aviation’s most iconic warbird, the enhanced SW-51 delivers both the performance and the soul.
