Gator RC Polyurethane Airplane Wheels with Aluminum Hubs (Pair)

Upgrade your RC airplane landing gear with a matching pair of Gator RC Polyurethane Airplane Wheels featuring durable aluminum hubs. These wheels combine a firm polyurethane (PU) tire with the strength and clean appearance of a machined metal hub.

Ten distinct diameters are available ranging from 57 mm (2.25 in) through 125 mm (5 in), making it simple to select the correct size configuration for your sport, scale, or giant-scale RC aircraft. Each package is sold as a matching pair of two wheels.

Axle Bore Sizing Split Rule:

To match the torque and structural requirements of different model sizes, the factory axle bore splits by diameter:

  • 4 mm Axle Bore: Features on the 2.25-inch, 2.5-inch, and 2.75-inch wheel sizes.
  • 5 mm Axle Bore: Features on all wheel sizes from 3 inches up to 5 inches.

🚀 Target Applications:

  • Main landing gear wheel tracking on grass strips or paved asphalt runways
  • Sport airplanes, precision aerobatic airframes, multi-engine aircraft, and giant-scale models
  • Replacing loose, compression-set foam tires with true-concentric rigid hub structures
⚠ Sizing & Clearance Notice: Confirm your required wheel diameter, wheel width, and main axle diameter before ordering. Verify there is sufficient clearance inside your fiberglass wheel pants and around retract wheel wells. Axles, landing gear tracks, and retention hardware like the Gator RC Wheel Collars are sold separately.

Key Features

  • Firm Polyurethane Tires: Resists flat-spotting, rotting, or tearing over multiple flying seasons, providing consistent rolling characteristics.
  • Rigid Aluminum Hubs: Machined metallic centers distribute impact forces evenly across the hub face during hard off-center arrivals.
  • Concentric Rotation Path: Precision core tolerances ensure true-tracking taxi turns and reduce high-speed ground vibration profiles.
  • Ten Scaled Diameters: Exhaustive sizing options simplify balancing tasks for small sport electrics up to heavy-metal 50cc-100cc warbirds.
  • Fulfillment Convenience: Ships out fully bundled as a two-wheel main landing gear pair to refresh your hardware from a single package.

💡 Installation Guide

  • Verify your specific landing gear wire or axle shaft diameter matches the chosen 4 mm or 5 mm wheel variant before final slide fitment.
  • Slide the wheel assembly onto the axle shaft, using matching inner and outer wheel collars to track placement layout settings.
  • Leave a small mechanical clearance gap between the metallic hub faces and your wheel collars to preserve free, non-binding rotation.
