The discontinued Airtronics 94734Z is a specialized 'Contest Retract' servo that is designed to provide reliable and powerful operation of retractable landing gear systems in high-performance aircraft. Unlike conventional servos, the 94734Z is engineered to provide a slow and realistic retraction and extension speed, adding a touch of scale realism to any model. Its powerful 5-pole motor and durable gear train provide the torque needed to operate even the largest and heaviest retract units, ensuring that the landing gear cycles reliably every time. The servo's dual ball bearings on the output shaft provide a smooth and precise action, minimizing slop and ensuring that the retract mechanism operates smoothly and without binding.
The 94734Z is a purpose-built servo that is designed to excel at its specific task. Its non-proportional, end-point-to-end-point operation ensures that the retracts are either fully up or fully down, with no in-between positions. The servo's robust construction and reliable performance have made it a trusted choice for competitive scale and pattern pilots who demand the best for their models. For those who are looking for a retract servo that can provide the ultimate in reliability and realism, the Airtronics 94734Z is the perfect choice.
This servo travels 170° from end to end only (not proportional).
