1.57 Inch Sponge Wheels for RC Aircraft

This set contains six pre-mounted sponge wheels designed for indoor and park flyer models. Each wheel has a 1.57 inch outside diameter and a 0.43 inch thickness. The 0.07 inch axle hole fits 2mm shafts commonly used on small electric airframes. Total weight for the set is 20 grams.

Upgrade from hard plastic or worn foam tires

Replace cracked plastic wheels that transmit vibration to the airframe or compressed foam that no longer rolls true. The sponge construction absorbs landing shock on grass or carpet without adding rotational mass. The improvement is worth it when take-offs become inconsistent or the model bounces on touchdown.

Fits lightweight electric models with 2mm axles

The 2mm bore matches the stock gear on many park flyers and indoor trainers. No adhesive or hub modification is required; press the wheels onto the existing axles and secure with the supplied collars. The low 20 gram set weight keeps the centre of gravity forward and leaves the recommended motor and battery combination unchanged.

Questions about this item

What axle diameter do the 1.57 inch sponge wheels need?

The wheels have a 0.07 inch (2mm) axle hole, so the axle must match that diameter for a secure fit.

How are the wheels attached, and what step is often missed?

Slide each wheel onto the matching 0.07 inch axle and secure it with a collar or set screw; forgetting the retainer lets the wheel slide off in flight.

When should the sponge tires be replaced?

Replace them when the sponge shows cracks, flat spots, or the 0.43 inch thickness has worn down enough to change handling.
