Built for RC helicopter control, the EMAX ES9254 Ⅱ combines a contactless magnetic encoder, digital control, a coreless brushed motor, and a full metal gear and housing design for responsive and precise operation.
The magnetic encoder provides less than 2° angle error and up to 360° effective control, helping deliver accurate position feedback during flight. Its dedicated RC chip is designed for fast response, with a response speed about twice that of conventional chips.
With a 25T output spline, ES9254 Ⅱ is designed for RC helicopters and offers speed up to 0.035 sec/60° at 8.4V, with torque up to 7.5 kg.cm.
The IP67 protection rating, metal gears, and metal housing provide added protection for outdoor flying conditions. Its compact 40 × 20 × 38.5 mm body weighs 72g and supports 6.0V to 8.4V input.

FAQ
Q:What is the EMAX ES9254 Ⅱ servo designed for?
A:The EMAX ES9254 Ⅱ is a digital magnetic encoder servo designed specifically for RC helicopters. It uses a 25T output spline, a coreless brushed motor, and a dedicated RC chip for responsive helicopter control. Its focus is fast response, precise position feedback, and stable control.
Q: What are the benefits of the magnetic encoder in the ES9254 Ⅱ?
A:The ES9254 Ⅱ uses a contactless magnetic encoder with angle error within 2° and up to 360° effective control. Because the sensing system does not rely on traditional mechanical contact, it provides precise position feedback while reducing mechanical wear.
Q:How fast is the ES9254 Ⅱ RC helicopter servo?
A:At 8.4V, the ES9254 Ⅱ reaches a speed of 0.035 sec/60°, with torque up to 7.5 kg.cm. It also uses a dedicated RC chip designed for faster response, making it suitable for RC helicopter applications where responsive control is important.
Q:Is the ES9254 Ⅱ servo durable and suitable for outdoor flying?
A:Yes. The ES9254 Ⅱ features metal gears, a metal housing, and IP67 protection. The IP67 rating provides protection against dust and water, making the servo suitable for outdoor RC helicopter use and changing flying conditions.
Q:What voltage does the ES9254 Ⅱ support?
A:The ES9254 Ⅱ supports 6.0V to 8.4V input. At 6.0V, it provides 0.05 sec/60° speed and 5 kg.cm torque. At 8.4V, it reaches 0.035 sec/60° and 7.5 kg.cm. The servo weighs 72g and measures 40 × 20 × 38.5 mm.
