Take your CR18P to the next level with a true Servo-On-Axle (SOA) setup. This CNC-machined aluminum conversion eliminates flex, improves steering precision, and adds low-mounted weight where it matters most for crawling performance.
More control. More strength. More capability.
🏁 Why Go SOA?
Moving the servo onto the axle improves steering response and geometry while reducing slop and flex found in chassis-mounted setups. Combined with the added aluminum strength, this upgrade transforms how your CR18P handles technical terrain.
