29 mm digital servo for use in large-scale models, especially in 1 : 5 scale model cars, where the demands on the servos are extremely rigorous. The RHINO digi 4 is fi tted with a generously dimensioned metal gearbox with a steel output gear terminating in an 8 mm splined spigot. The integral aluminium heat-sink guarantees effective cooling of the motor and the electronics. The servo case is sealed with O-rings to prevent the ingress of dust and spray. The servo’s enormous torque and robust nature also make it an excellent choice for use in large-scale model aircraft, e.g. F3A-XXL.
