How to Maintain Your RC Car
Most RC car problems come from a handful of avoidable causes: dirt left to sit, a loose screw that was never checked, or a battery stored the wrong way. A few minutes of upkeep after each run goes a long way.
After every run
Wipe or brush off dirt and debris, especially around the wheels, suspension, and any exposed gearing — dirt left to sit is one of the most common causes of premature wear. If you drove through water or mud, dry the car off and, if your electronics aren't sealed, check that nothing is sitting wet before it's put away.
- Brush or wipe down the chassis, wheels, and suspension arms
- Check that the battery connector and wiring look undamaged
- Store the LiPo at storage charge, not full, if it won't be used for a while
Every few runs
Check screws and shock mounts for anything that's worked loose — vibration loosens fasteners over time, and it's much easier to catch a loose screw at home than mid-drive. Take a look at the tires for uneven wear and the drivetrain for any play or grinding that wasn't there before.
Storage
Store the car somewhere dry, out of direct sun (UV and heat degrade tires and plastic over time), and — if it'll sit for more than a couple weeks — with the battery removed and at a safe storage charge rather than full or empty.
Frequently Asked Questions
Differentials and some gear sets benefit from occasional greasing, and shocks may need fresh shock oil if they start feeling stiff or leak — check your specific model's manual, since intervals vary. Bearings occasionally benefit from a drop of light oil if they start feeling rough.
Noticeably shorter run times, the car feeling less powerful than it used to, or a battery that feels puffy/swollen are all signs. A swollen LiPo should be retired and disposed of properly — don't keep charging or using one.
