The O.S. Engine 46VX-DF ABC is tailored to medium-sized jet models and delivers an estimated 25% power gain over the 46VR-DF. This makes it a practical option for pilots wanting stronger climb rates and steadier cruise at model scale speeds.
A precision drum valve induction system lies at the core of this engine, improving fuel metering for predictable throttle response and even power spread. The high-performance carburettor further aids efficient running in both forward and rear-mounted setups.
Design enhancements focus on thermal management and rigidity. The bar stock head promotes better heat transfer while the larger fin profile increases cooling. Strengthened crankcase webbing minimises distortion during high speed operation and the integrated crankcase design supports durability.
The bolt-on exhaust adapter offers flexible exhaust positioning, allowing builders to select systems that match installation space and desired acoustic characteristics.
The 46VX-DF ABC is aimed at advanced modellers who require a compact, higher-output engine with practical installation options and robust construction.
