Dubro’s Super Strength Servo Arms deliver a rigid, non‑flex feel for precise control. Moulded from long fibre composites, this DUB674 pack supplies eight standard JR/Spektrum‑type arms in grey, suitable for aircraft, car, boat and helicopter models.

Two horn lengths and four horn styles provide setup flexibility, while the longer versions increase throw for greater control movement. The robust, durable design helps resist slop under high load.
