RVK rc have introduced new UFO wing washers for 1/8 nitro/electric buggies and truggy. The lightweight washers are made out of black nylon plastic and sport a “flying saucer” style. These large diameter washers (20mm) prevent the wings from excessive bending under high loads and thus improve aerodynamic efficiency. The set includes two UFO wing washers, without screws.
