40mm Foam Wheel For Aeromodelling

40mm Foam Wheel For Aeromodelling is a lightweight, high-durability landing gear component engineered specifically for radio-controlled (RC) aircraft, park flyers, and lightweight drone models. Consequently, it minimizes overall take-off weight while providing smooth roll characteristics during taxiing, take-offs, and landings. The wheel combines an ultra-light dense EVA foam tire with a rigid plastic hub, ensuring optimal shock absorption on uneven runways. Furthermore, its tough material construction resists deformation under repetitive impact loads. Therefore, you can reliably install this wheel onto your model aircraft landing gear to improve ground handling and cushion hard landings.

Key Features:

• Ultra-Lightweight Design: Features high-density foam construction, which minimizes extra weight on the airframe for maximum flight efficiency.
• Shock-Absorbing Tire: Absorbs ground impacts effectively, protecting delicate landing gear linkages and fuselage structures during rough landings.
• Durable Plastic Hub: Houses a rigid inner core that prevents axial wobbling and maintains true rotation on the axle.
• High-Traction Tread Surface: Provides adequate grip on grass, asphalt, and dirt runways without causing high rolling resistance.
• Universal Axle Compatibility: Accommodates standard model airplane landing gear wire axles for quick and straightforward mounting.

Technical Specifications:

• Outer Diameter: 40.0 mm (≈ 1.57 inches)
• Wheel Width (Thickness): ≈ 12.0 mm
• Axle Hole Diameter (Bore): ≈ 2.1 mm (Designed for 2.0 mm steel wire axles)
• Maximum Recommended Aircraft Weight: ≈ 500 g per wheel
• Operating Temperature Range: −10°C to +60°C
• Foam Density: High-Density EVA (Ethylene-Vinyl Acetate)

Mechanical Specifications:

• Tire Material: High-density closed-cell EVA foam
• Hub Material: Injection-molded ABS / Nylon plastic
• Mounting Style: Push-fit on wire axle with metal wheel stoppers/collars
• Wear Resistance: Excellent resistance to abrasion, UV exposure, and moisture

Dimensions:

• Outer Diameter: 40.0 mm
• Rim / Hub Diameter: ≈ 18.0 mm
• Total Thickness: ≈ 12.0 mm
• Center Bore Diameter: ≈ 2.1 mm
• Weight: ≈ 2.2 g per wheel (Ultra-light profile)

Pinout and Wiring:

• Non-Electrical Component: This wheel functions purely as a mechanical landing gear accessory and requires no electrical wiring or pinout connections.
• Assembly Instruction: Slide the wheel onto a 2.0 mm landing gear wire axle and secure it in place using standard metal wheel collars on both sides.
• Installation Note: However, ensure you leave a tiny clearance between the wheel collar and plastic hub so the wheel spins freely without friction.
