Du-Bro 325R 3-1/4″ Smooth Wheel — 2-Pack

The 325R wheel pair emphasizes balance with a uniform wall thickness that helps maintain a steady roll on variable terrain. The kit includes a sporty nylon metallic hub, which pairs well with many RC bush plane configurations. These wheels are known for reliability in models that require a consistent, controlled takeoff or landing on uneven runways. They are a good baseline option for pilots prioritizing predictable handling over extreme off-road performance.
Key considerations: compatibility with standard axles, replacement availability, and whether your plane needs a non-inflatable wheel for lower maintenance. For small-to-mid-sized bush planes, the 3-1/4″ diameter can offer enough ground clearance without adding excessive unsprung weight. Users who fly primarily on grass strips may appreciate the stable roll and reduced bounce compared to larger inflatable wheels.
Du-Bro 400RV 4″ Big Wheel — 2-Pack

The 400RV is a larger, smooth inflatable wheel designed to soak up rough surfaces and softer fields. It features a positive-seal air valve and two-piece bolt-together hubs with hub caps, making maintenance straightforward. The inflated tire can compensate for minor ground irregularities, which helps tame bumpy takeoffs and landings common in bush flying. This wheel is ideal for pilots who regularly operate from gravel, dirt, or grassy fields with irregularities.
Important details include the ability to inflate or deflate via a side valve, which allows field adjustments based on surface conditions. The larger diameter improves obstacle clearance, but it may require more frame clearance and may affect ground handling in tight spaces. Always confirm clearance with your aircraft’s struts and wheel wells before purchasing.
uxcell Tire And Wheel Sets — 2.75″ PU Sponge

uxcell offers a compact option with PU sponge tires and a plastic hub. With an outside diameter of 2.75″ and a light 10g per piece weight, these wheels are well-suited for smaller bush planes or as lightweight replacements where weight savings matter. The plastic hub provides adequate rigidity for typical RC airframes, while the soft PU material can cushion minor impacts during field operations. This set is a good match for micro to mid-size aircraft that require nimble handling and a lower overall wing loading profile.
Consider compatibility with your existing axles (3mm axle holes) and whether your craft benefits from a lighter wheel assembly. If you fly on compact fields or you require a quick replacement option, this set offers an affordable balance of weight and practicality. Ensure the tire thickness and hub diameter align with your wheel wells to avoid contact with the airframe during full suspension travel.
Fielect 5″ Super Light Sponge Wheel Set — 2 Pcs

The Fielect 5-inch set targets larger bush planes with its super-light PU sponge tire and aluminum alloy core hub. The 5″ diameter is designed to deliver improved ground clearance and smoother landings on uneven fields. The hub’s aluminum core adds strength while maintaining a lighter overall weight, which is beneficial for flight balance and performance. This option suits pilots who fly from roughed-up or improvisational airstrips and want a light wheel assembly that still handles field irregularities well.
Key attributes: larger diameter for high-clearance operations, robust hub construction, and a balance of lightweight design with load-bearing capacity. Verify axle hole diameter (5.5mm) to ensure a proper fit with your axle hardware. Consider how this wheel’s size interacts with your plane’s gear struts and wheel pants, if used, to avoid ride interference during takeoffs and landings.
Du-Bro 500RV 5″ Big Wheel — 2-Pack

The 500RV model is a larger 5″ inflatable wheel offering robust performance on rough terrain. Like the 400RV, it includes smooth inflatable tires and a positive seal air valve, with two-piece hubs and hub caps for straightforward maintenance. This size is particularly useful for bush planes operating from unpaved runways, gravel, or dirt strips where extra ground clearance and better shock absorption are valuable. This wheel helps reduce bounce and improves stability during rollout on unpredictable surfaces.
When selecting a 5″ wheel, ensure your gear leg geometry allows the additional diameter. Check for adequate wheel well clearance, strut travel, and whether your aircraft’s wheel pants or fairings accommodate the larger wheel. This option is best for pilots who regularly land on rough surfaces and need reliable, long-lasting components that can withstand frequent field use.
Buying Guide: Key Purchase Considerations For RC Bush Plane Wheels
- Wheel diameter and ground clearance — Larger wheels provide better obstacle clearance and smoother landings on rough fields, but may require more space and frame clearance.
- Wheel type — Inflatable tires absorb shocks and handle uneven terrain better; solid or sponge tires offer lower maintenance and weight benefits but may transmit more vibration.
- Hub construction — Metal or aluminum hubs tend to be stronger and more durable; plastic hubs save weight but can wear faster under aggressive use.
- Axle compatibility — Confirm axle hole diameter and mounting style (two-piece hubs, bolt-together designs) to match your aircraft’s gear.
- Field conditions — Rough, dirt, or grassy runways favor larger or inflatable wheels with better shock absorption; smooth lawns or carpeted areas may do well with smaller, lighter wheels.
- Maintenance needs — Inflatable wheels require valve checks and occasional inflation/deflation; sponge tires reduce maintenance but have different wear characteristics.
- Weight considerations — Heavier wheels affect aircraft balance and performance; balance weight with scale performance in mind, especially for smaller airframes.
- Compatibility with gear and wheel pants — Ensure the chosen wheels fit your struts, wells, and any wheel pants to avoid interference during operation.
In summary, choosing RC bush plane wheels involves balancing diameter, weight, and terrain compatibility. Larger wheels improve rough-field performance, while lighter or sponge-wheel options can benefit overall flight characteristics for smaller planes. Always verify fit with your specific airframe, as even slight mismatches can impact stability during takeoff and landing on off-airport surfaces.
