The Ultimate Buying Guide for Your 6S RC Car
Ready to jump into the fast lane of the RC world? A 6S (Six Series) RC car runs on a powerful 6-cell LiPo battery setup. This means serious speed and exciting power! This guide helps you choose the right one.
Key Features to Look For
When you shop for a 6S car, certain features make a big difference in how fun and durable it will be.
Speed and Power System
- Brushless Motor and ESC: Always choose a brushless system. These motors are much faster and last longer than brushed motors. The Electronic Speed Controller (ESC) must be rated for 6S voltage. Check the Amperage rating; higher is usually better for power handling.
- Motor Size (Kv Rating): The Kv rating tells you how fast the motor spins per volt. Lower Kv ratings (around 1800Kv to 2200Kv) are common for large 6S bashers, offering great torque. Higher Kv means more top speed but requires careful cooling.
Chassis and Drivetrain
- Drivetrain Type: Most high-power 6S cars are 4-Wheel Drive (4WD). This gives you the best traction for launching quickly.
- Shocks and Suspension: Look for oil-filled aluminum shocks. Plastic shocks leak fluid and don’t handle big jumps well. Good suspension soaks up rough terrain.
Durability and Maintenance
- Gearing: Metal spur gears and pinions are essential for handling 6S power. Plastic gears will strip quickly.
- Waterproofing (or Water Resistance): If you plan to drive in wet grass or puddles, ensure the ESC, receiver, and servo have good water resistance ratings.
Important Materials Matter
The stuff your car is made of directly impacts how long it lasts when you push its limits.
Chassis and Arms
- Chassis Material: Aluminum chassis plates offer stiffness and good looks. Composite plastic chassis are lighter and slightly more flexible, which can help absorb minor impacts without bending.
Drivetrain Components
- Driveshafts and Outdrives: Steel driveshafts handle the extreme torque of a 6S setup much better than plastic ones. Check if the car uses CVA (Constant Velocity Axles) or dog bones; CVA designs are generally stronger.
Bumpers and Body
- Bumpers: Thick, flexible plastic bumpers protect the front and rear when you crash (and you will crash!).
- Body Shell: Polycarbonate (Lexan) bodies are standard. Thicker Lexan resists tearing better.
Factors That Improve or Reduce Quality
Quality isn’t just about price; it’s about smart engineering choices.
Quality Boosters
- Bearing Quality: Full ball bearings throughout the drivetrain reduce friction and increase efficiency. Cheaper cars might use bushings in some spots, which wear out quickly.
- Heat Management: High-quality ESCs and motors usually have built-in cooling fans. Adding an aftermarket heatsink to the motor helps prevent overheating during long, hard runs.
Quality Reducers
- Proprietary Parts: If a car uses many unique, non-standard parts, repairs get expensive and difficult. Look for cars that use common, replaceable components.
- Weak Servo Saver: A weak servo saver allows the steering servo to be damaged on hard front impacts. A strong, adjustable saver protects your steering system.
User Experience and Use Cases
Think about where you will drive your new machine.
Terrain Types
- Bashing (General Fun): If you plan to jump high and drive hard over mixed surfaces (grass, dirt, pavement), you need a robust truck or buggy with high ground clearance. Durability is key here.
- Speed Runs: If pure straight-line speed is your goal, you need a low-slung, aerodynamic chassis (like a speed run specific car or a low-slung SCT). These often require special tires that won’t explode at high speeds.
- Track Racing: For dedicated dirt or asphalt tracks, look for cars designed as racing buggies or short-course trucks (SCTs). These prioritize handling and precise steering over raw bashing toughness.
Learning Curve
6S power is intense! Beginners should look for models that allow you to easily limit the throttle power via the ESC programming until you get used to the speed. Experienced drivers can immediately unlock the full potential.
10 Frequently Asked Questions (FAQ) for 6S RC Cars
Q: What exactly does “6S” mean?
A: “6S” means the car uses a battery pack made of six individual Lithium Polymer (LiPo) cells connected in series. This provides a high voltage (usually around 22.2V fully charged), which creates massive power and speed.
Q: Is a 6S car too fast for a beginner?
A: Yes, they can be very fast! Most modern 6S ESCs let you program a “Training Mode” or limit the throttle percentage so beginners can learn control before unleashing full speed.
Q: What kind of battery do I need for a 6S car?
A: You must use a dedicated 6S LiPo battery. These batteries typically have a high C-rating (discharge rate) to deliver the necessary current for the motor.
Q: Do I need a special charger for 6S batteries?
A: Absolutely. You need a LiPo charger that is capable of balancing and charging 6S packs (meaning it can handle up to 6 cells or 25.2V charging voltage).
Q: What is the main difference between a 4S and a 6S car?
A: 6S cars are significantly faster and have much more torque than 4S cars because they run at a higher voltage. They also generally require stronger, more durable components to handle the extra stress.
Q: How hot should my motor get?
A: Motors run best when they stay under 160°F (about 71°C). If you touch the motor and it’s too hot to hold for more than a second, you need to slow down or install a fan.
Q: Are 6S cars durable enough for jumping?
A: High-quality 6S models are built tough for “bashing,” which includes jumping. However, the quality of the shocks and the strength of the suspension arms will determine how well they survive repeated hard landings.
Q: What is ‘cogging’ and how does it affect my car?
A: Cogging is a slight resistance you feel when manually turning the motor shaft while the power is off. It is normal, but excessive cogging can sometimes indicate a problem with the motor magnets or bearings.
Q: Should I buy a RTR or a Kit?
A: “Ready-to-Run” (RTR) cars come fully assembled with electronics installed. Kits require you to build the entire car, which is great for learning but takes much more time. For most users, an RTR 6S is recommended.
Q: Do I need special tires for high speeds?
A: Yes. Standard off-road tires can balloon or even explode when driven over 50 mph. For high-speed runs, you must use foam-reinforced or specifically rated speed run tires.
