• Extreme 19,000 RPM Performance: Engineered for competitive RC racing with 2.1kW power output at 13,000 RPM and peak torque of 1.76N·m at 9,000 RPM. Precision-balanced crankshaft maintains stability at maximum no-load speeds while delivering explosive acceleration for BAJA-style off-road terrain
• Competition-Grade Mounting System: Four-point reinforced mounting design ensures vibration-free operation during high-G maneuvers. Aircraft-grade aluminum brackets withstand extreme impacts while maintaining perfect alignment - critical for maintaining drivetrain integrity at competition speeds
• Advanced Thermal Regulation: Dual-cooling architecture combines forced-air cooling with specialized cylinder fins and flywheel blades. Actively dissipates heat during sustained high-RPM operation, preventing performance drop-off in desert racing conditions or extended sessions
• Ultralight Power-to-Weight Ratio: At only 4.83 lbs (2.19kg) with compact 6.3x5.91x7.87-inch dimensions, this engine outperforms heavier alternatives in throttle response. Reduces overall vehicle weight for improved jumps and cornering while maintaining 30.5cc displacement class dominance
• Track-Ready Reliability Features: Simplified recoil pull-start ensures instant ignition in all conditions. Mixed-oil lubrication system (25:1-50:1 ratio) maintains critical component protection during high-stress operation. Modular design enables rapid spark plug access and field maintenance between heats
