What's Included in RTR vs Kit Cars

RTR cars arrive pre-assembled with 6 essential components:

• Pre-assembled chassis with all components installed
• Electric motor (brushed or brushless depending on model)
• Speed controller (ESC) for motor control
• Steering servo for wheel control
• Radio system (transmitter and receiver)
• Battery charger (basic charger included)

RC car kits include only mechanical components and require separate electronics purchases:

• Unassembled chassis with all mechanical parts
• Body shell (usually clear, requires painting)
• Wheels and rims (tires often sold separately)
• Hardware and bearings for assembly
• Instruction manual with detailed diagrams

Ready-to-Run RC cars eliminate assembly time. You only need to charge the battery and start driving.

Kits require separate electronics purchases including motor and ESC, servo, transmitter, receiver, battery, and charger. Kits don't include these components because hobbyists prefer choosing their own electronics like brushless motors, programmable ESCs, and high-torque servos based on performance needs and budget.

Cost Comparison: RTR vs Kit Build

RTR cars cost $200-800 complete, while equivalent kit builds range $250-1200 depending on electronics quality chosen. The best RC car kits may be the best value if you plan extensive upgrades, but RTR models offer better immediate value for beginners.

Popular RTR models like Traxxas Slash 4WD Ultimate Clipless (579,95 €) include everything needed, while building an equivalent kit requires:

• Kit chassis: $180-250
• Motor and ESC: $80-200
• Servo: $25-60
• Radio system: $60-150
• LiPo battery: $35-80
• Charger: $40-120

Assembly Time and Skill Requirements

RTR cars require 0-15 minutes setup time, while building an RC car from a kit needs 4-8 hours assembly plus electronics installation experience. First build projects often take longer as you learn proper techniques and basic tools usage including hex drivers, side cutters, and screwdrivers.

Building kits develops essential skills:

• Mechanics and electronics understanding
• Time and patience for detailed assembly
• Customization and learning opportunities
• Problem-solving when issues arise

RTR models provide immediate RC experience without build time, letting you focus on RC driving skills and track performance.

Performance and Customization Differences

RTR cars offer limited upgrade options with basic electronics like brushed motors, basic ESCs, and plastic servos, while kits allow unlimited customization from component selection through final setup.

RTR Advantages:

• Ready to use right after charging
• Proven compatibility of all components
• Warranty coverage on complete vehicle
• Option for beginners to learn driving first

Kit Advantages:

• Customizable performance setup
• Higher quality components available
• Learning opportunity about RC mechanics
• Upgrade path matches skill development

Electronics and Upgrade Considerations

Choose between basic RTR electronics or custom kit components based on your performance goals and budget. Building an RC car from a kit lets you choose:

• Motor options: Brushed for beginners, brushless for performance
• ESC features: Programming options like timing adjustment, brake strength, and throttle curves, voltage handling
• Servo quality: Speed, torque, and precision
• Radio system: Channel count and advanced features such as telemetry, model memory, and dual rates
• Battery type: NiMH for simplicity, LiPo for performance

Kits often require additional purchases like RC connectors including XT60, Deans, and EC5 plugs and assembly tools like hex drivers, side cutters, and bearing tools, but allow future upgrades without compatibility concerns.

Which Type Should Beginners Choose?

Beginners get the best results from RTR cars because they focus on driving skills before learning assembly and tuning. Best RC cars for beginners include everything needed to start your RC experience immediately.

RTR vehicles provide immediate benefits for new hobbyists:

• Start driving within minutes of opening the box
• Learn vehicle handling and control
• Understand basic maintenance needs
• Decide if they enjoy the hobby before major investment

Once comfortable with RC driving, many hobbyists upgrade to kits for deeper customization and learning opportunities.

Maintenance Requirements

Both RTR and kit cars require identical maintenance schedules for optimal performance. Basic RC car maintenance includes:

• Tightening screws regularly after driving sessions
• Cleaning chassis and drivetrain components
• Checking differential oil levels
• Inspecting wear items like tires, gears, and bearings

Building kits provides maintenance advantages - knowing how you assembled the car makes maintenance and repairs easier.

Checklist for Buyers

Essential checklists prevent common oversights that can delay your first drive or building project:

Ready-to-Run (RTR) Cars

• Charge the battery before first use
• Install transmitter batteries (usually 4 AA batteries)
• Check all screws are properly tightened
• Consider backup battery for extended runtime
• Plan for eventual upgrades as skills develop

RC Car Kits

• Choose electronics: motor, ESC, servo, radio system
• Purchase battery and charger separately
• Gather tools: hex drivers including 1.5mm, 2.0mm, and 2.5mm sizes, screwdrivers, side cutters
• Plan build time: 4-8 hours depending on experience level
• Consider paint for the body shell customization like Tamiya PS series or Parma Faskolor

RTR vs RC Kit FAQs

What does 2S and 3S mean in RC cars?

2S and 3S refer to LiPo battery cell counts. A 2S battery has 2 cells producing 7.4 volts, while a 3S battery has 3 cells delivering 11.1 volts. More cells increase speed and power output in brushless motor setups.

What does KV mean on brushless motors?

KV measures RPM per volt on brushless motors. A motor with 3000KV will spin at 3000 RPM for every volt applied. Higher KV values increase speed, while lower KV values offer more torque and control.

What is a PNP RC plane?

PNP stands for Plug-N-Play - a model that includes all electronics like motor, ESC, and servos pre-installed but excludes the transmitter and receiver. Users add their own radio system to complete the setup.

What is the top speed of an RC car?

RC car speeds range from 30 to over 100 mph depending on model and battery. High-end brushless models with 3S or 6S LiPo batteries exceed 100 mph, while standard RTR cars typically reach 30–60 mph.

One Last Thing to Remember When Choosing RTR or RC Kit

Both RTR and kit cars lead to the same destination: enjoying the exciting world of radio-controlled vehicles. Whether you pick the instant gratification of RTR or the satisfaction of building and customizing a kit, you'll join a community of enthusiasts passionate about RC performance and fun.
