Can these wheels help on tall grass runways?
The 3-inch diameter is larger than typical micro wheels, providing enough clearance to roll over taller grass without bogging down. This makes take-offs and landings smoother on grass fields commonly used for park flyers and lightweight models.
Are these wheels only for RC aircraft?
While designed for electric park flyers and lightweight gas models, the wheels can be used in school projects, crafts, or other lightweight rolling applications. The nylon hub accepts standard axles, making them versatile for custom builds.
What is the build quality like?
DU-BRO has been manufacturing hobby products since 1959. The closed-cell foam won't absorb moisture, and the nylon hub resists cracking. The tread pattern provides grip on grass, dirt, and paved surfaces.
