It is not suitable for beginners, inexperienced customers, or children without direct supervision from a responsible, knowledgeable adult.

Function Description:

The XRAY X10 is a high-performance remote-controlled car built for competitive racing. Its design allows for extensive customization and tuning to adapt to various track conditions and driving styles. Key adjustable features include front suspension flex, caster, ride height, droop, rear pod pivot mounting, side spring settings, shock absorber setup, and track width. The car is designed to be assembled by the user, offering a hands-on experience in building a high-quality racing machine.

Important Technical Specifications:

• Scale: 1/10
• Type: Luxury Electric GT Pancar
• Chassis: X10'22 Graphite Chassis 2.5mm (Part #371024)
• Front Suspension: Features adjustable flex settings (Soft, Medium, Stiff) and caster adjustment via shims under the front ball. King pin axles are 4mm, with options for 1°, 1.5°, and 2° camber. Front coil springs are available in various stiffnesses (C=1.5-1.7 Gold, C=1.8-2.0 Silver, C=2.1-2.3 Black).
• Rear Suspension: Includes adjustable pod linkage positions (Outer/Inner) and pivot mounting alternatives (Rearward/Forward) to influence steering and rear traction. Side springs are available in multiple stiffnesses (C=0.6 Silver, C=0.9 Gold, C=1.2 Black, C=1.5 Silver, C=1.8 Gold).
• Differential: Ball differential with various spur gear options (72T/64P to 96T/64P) or an optional XRAY Gear Differential. Ceramic axial thrust bearings (F3-8 3x8x3.5mm) and ceramic balls (3.175mm) are used.
• Shock Absorber: Configurable as Short Shock (without adaptor) or Long Shock (with adaptor). Damping is adjustable using different silicone oils (from 100cSt to 2000cSt) and various spring stiffnesses (C=1.5 Silver to C=3.1 Black 4 Dots).
• Steering: Features adjustable Ackermann settings through steering link mounting positions and ballstud shims. Bump steer can also be adjusted using shims.
• Electronics (Not Included): Requires a transmitter, receiver, speed controller, electric motor, pinion gear, LiPo battery, battery charger, steering servo, and personal transponder.
• Wheels & Tires (Not Included): Requires 1/10 GT bodyshell, wheels, and tires.
• Materials: Utilizes high-quality graphite parts, aluminum components (e.g., rear bulkheads, diff hubs, wheel hubs), and composite parts.

Usage Features:

• Customization: The XRAY X10 offers extensive tuning options to adapt to different track conditions and driving preferences. This includes adjusting front and rear suspension settings, differential tightness, shock damping, and chassis flex.
• Front Suspension Flex: Three main settings:
  • Soft (No Brace): Less responsive, more mechanical grip, recommended for low-grip carpet and asphalt.
  • Medium (Initial Setting): Balanced response and mechanical grip, recommended for most conditions.
  • Stiff: Maximum responsiveness, decreased mechanical grip, recommended for high-traction conditions (e.g., US black carpet).
• Caster Adjustment: Shims under the front ball adjust caster angle, affecting steering and stability.
• Ride Height & Droop Adjustment: Adjustable via shims under the arms and steering block, and by preload of the front spring. Lower ride height for stability on smooth tracks, higher for bumpy tracks. More droop for front grip, less for quicker direction changes.
• Rear Pod Pivot Mounting:
  • Rearward (Initial Setting): More steering, free rear end, recommended for high-traction conditions.
  • Forward: Balanced front and rear traction.
• Side Springs: Different stiffnesses affect car roll and feeling (stiffer for less roll, softer for more roll).
• Shock Absorber Settings:
  • Short Shock: Improves steering response, quicker direction changes.
  • Long Shock: Improves driveability over bumps, better on-power traction.
  • Damping: Thinner oil for low-traction tracks, thicker oil for high-traction tracks. Thicker oil increases stability but decreases cornering speed.
• Ackermann Setting: Adjustable via wheelbase length and steering block linkage position, influencing steering lock on inner/outer wheels.
• Track Width: Shims behind the wheel bearing adjust front track width. Wider track for easier driving, less steering; narrower track for more steering, more responsive.
• Electronics Configuration: Offers rearward (initial) and forward positions for battery pack, receiver, and speed controller, allowing for weight distribution tuning.
• Servo Compatibility: Supports standard and mid-size servos with appropriate mounts.

Maintenance Features:

• Regular Checks: Periodically check and tighten all fasteners. Ensure free movement of all parts, especially ball-bearings.
• Graphite Parts Preparation: Sand and apply CA glue to the edges of all graphite parts to protect and seal them.
• Shock Absorber Maintenance:
  • Fill shock body with oil and remove air bubbles for smooth operation.
  • Ensure the shock shaft moves freely after assembly.
  • Tighten shock caps fully but avoid overtightening to prevent damage to the rubber membrane.
• Side Tube Maintenance: Add oil to each slot of the composite side tubes. Re-oil at least once per race day for smooth operation.
• Differential Maintenance:
  • Apply a very small amount of bearing oil to ball bearings.
  • Apply diff grease to differential components.
  • Tighten the diff nut gently to prevent slipping under power, but avoid overtightening to prevent damage to diff balls and/or plates.
• King Pin Axle Maintenance: Apply HUDY Silicone Oil (10K cSt included) to the king pin axles for smooth operation.
• Arm Reamer Usage: If suspension arms do not move freely, use a 4mm Arm Reamer to size the holes, removing only enough material for free movement without excessive play.
• Gear Mesh Adjustment: Adjust the gear mesh between the spur gear and pinion teeth to ensure appropriate space and free play.
• Battery Care: Disconnect the battery pack before storing the model. Use a recommended charger and avoid overcharging. Dispose of batteries responsibly.
• General Safety: Always wear protective glasses and gloves when building and operating. Keep small parts out of reach of children. Avoid touching hot components after use. Ensure operating frequency is clear before use. Turn on transmitter before receiver, and turn off receiver before transmitter.
