Professional IU-C+-006K Micro 5-Speed Transmission with Integrated Clutch
[Product Overview]
This is a high-precision, industrial-grade manual transmission system designed for multi-cylinder RC engines (V2 to V12). Featuring a complex 5-speed forward + reverse gear structure and a functional mechanical clutch, it provides the ultimate realistic driving experience for custom scale automotive builds.
[Advanced Technical Features]
Dynamic Shifting Logic: Equipped with a dual-servo control system. One servo manages the 2-1-N-S forward sequence, while a second independent servo controls the Reverse (R) gear.
Integrated Mechanical Clutch: Allows for authentic power disconnection between the engine and the drivetrain.
Precision Gear Ratios: * 1st Gear: 1.89 : 1
2nd Gear: 1.15 : 1
S-Gear (High): 3.36 : 1
Dual-Stage Output Shaft: Features a 5mm D-segment for secure torque transfer and a 4mm round segment for standard RC couplings.
[Maintenance & Lubrication - Critical]
To ensure longevity and smooth operation, this gearbox requires internal lubrication:
Oil Type: 5W-40 Mechanical Oil (or high-grade engine oil).
Capacity: 30ml - 40ml.
Break-in Period: A full oil change is required after the initial 3-5 hours of operation to remove metallic wear particles.
[Safety & Operation Warning]
⚠️ IMPORTANT: Shifting gears must ONLY be performed when the clutch is fully disengaged and there is no power input from the engine. Shifting under load or without the clutch will cause immediate and permanent gear damage.
[Physical Specifications]
Total Length: 166.9 mm
Total Height: 75.9 mm
Engine Compatibility: Perfect for Toyan V8/V12, Enjomor, and other high-torque micro engines.
Mounting: Features standard M3 screw ports for secure chassis mounting and oil drainage.
