Team Associated developed a new Medium composite arm material for 1:8 off-road racing. Compared to the RC8B4 kit Hard material, the Medium arms have reduced fiber content which offers several improvements. Medium arms are marked with a blue dot on all parts.
Benefits of Medium arms
Increased impact strength while maintaining responsive racing feel
Increased durability in cooler temperature range
More grip on low traction conditions where added flex makes the car more forgiving
Slightly reduced weight of approximately 1.5 grams per arm
