Do any players know where to buy HBX 901 901A RC car to ensure good quality? I bought one and found the quality to be mediocre, if any players can recommend me I would be very grateful.

Regular maintenance, such as cleaning and lubricating the motor, can extend its lifespan.

Additionally, avoid over-stressing the motor by driving the car on rough terrains for extended periods. Use genuine replacement parts to ensure compatibility and performance.

Check the batteries first and replace them if necessary. Make sure all connections between the remote control and receiver are clean and tight.

Try resetting the remote and receiver by turning them off and back on.

If the problem persists, check the remote for any visible damage and check the buttons or joystick for any obstructions.

You can reinforce the swing arms by adding metal braces or using aftermarket arms made from stronger materials.

Additionally, avoid driving on extremely rough terrains or at high speeds, as these can increase the risk of damage.

Regularly inspect the swing arms for any cracks or wear and replace them as needed.

A thicker oil will provide more drag, reduce wheel spin and increase traction, while a thinner oil will give smoother, faster differential action. For off-road driving, a thicker oil is usually preferred to handle rough road conditions and maintain traction.
For on-road driving, a thinner oil provides smoother cornering and better acceleration.
