To bind the transmitter to the receiver, turn on the transmitter first, then press and hold the bind button on the receiver while turning it on. Release the bind button once the LED on the receiver stays solid, indicating a successful bind.
The recommended battery type for the Micro RS4 117141 Race Kit is a 6-cell 7.2V NiMH battery pack. Ensure it fits securely in the battery compartment and is properly charged before use.
The suspension can be adjusted by changing the shock oil viscosity and spring tension. Use softer springs or lighter oil for more grip and harder springs or thicker oil for more stability on smooth surfaces.
First, check the servo connections and ensure they are secure. Then, verify that the steering trim on the transmitter is correctly set. If the problem persists, inspect the servo for damage or replace it if necessary.
Regular maintenance should be performed after every 5-10 runs. This includes checking for loose screws, inspecting the drivetrain for debris, lubricating moving parts, and ensuring the electronics are free from dust and moisture.
Check the gear mesh between the pinion and spur gear for proper engagement. Also, ensure the motor connections are secure and not damaged. If the issue continues, inspect the ESC and recalibrate if necessary.
To replace a broken wheel, remove the wheel nut using a suitable wrench. Take off the damaged wheel, place the new wheel on the axle, and secure it with the wheel nut. Ensure it's tightened properly to avoid wobbling.
Check the wheel alignment and adjust the steering trim on the transmitter. Inspect the tire wear and replace if necessary. Ensure that all suspension components are intact and not bent or damaged.
Use a soft brush or compressed air to remove dirt and debris from the chassis and suspension. Avoid using water to prevent damage to electronic components. For stubborn grime, use a damp cloth and ensure everything is dry before storing.
Upgrades include high-performance motors, aluminum suspension components, adjustable shocks, and high-grip tires. These can enhance speed, handling, and durability of the Micro RS4.
