BEFORE YOU START This is a high-competition, high-quality RC car intended for persons aged 16 years and older with previous experience building and operating RC model racing cars. This is not a toy; it is a precision racing model. This model racing car is not intended for use by beginners, inexperienced customers, or by children without direct supervision of a responsible, knowledgeable adult.
IMPORTANT NOTES – ELECTRICAL • Insulate any exposed electrical wiring (using heat shrink tubing or electrical tape) to prevent dangerous short circuits. Take maximum care in wiring, connecting and insulating cables. Make sure cables are always connected securely. Check connectors for if they become loose. And if so, reconnect them securely. Never use RC models with damaged wires. A damaged wire is extremely dangerous, and can cause short-circuits resulting in fire.

1. GEAR DIFFERENTIAL CARPET OIL 964031 Rear diff Silicone oil 5.000cSt Fill just above the diff pin. S 3.5x10x0.2 USE PROPER AMOUNT OF OIL IN THE DIFFS Use a digital scale to measure the exact amount of oil in the diff. Remember that during operation the diff gets hotter and the heat may allow the oil to expand. If there is too much oil inside it may interfere with the diff operation and damage the internal gears. Fill differential up to the top of the diff pin.

MAINTENANCE SHOCK MAINTENANCE The most important maintenance task for keeping consistent shock performance is refilling and bleeding them correctly. If built correctly, it will not be necessary to re-build them often. Replacing warped/hard o-rings, scarred piston rods, or shaved/split/loose composite upper and lower ball joints are also important. • For club racing, it is recommended to check the shocks for air inside before each race and only re-fill and bleed them if necessary.
