FAQ
Frequently asked questions
What is the ES9254 II designed for?
It is a digital magnetic-encoder servo designed specifically for RC helicopters. Its 25T output spline, coreless brushed motor and dedicated RC chip support responsive helicopter control.
What are the benefits of its magnetic encoder?
The contactless magnetic encoder keeps angle error within 2° and supports up to 360° effective control, providing precise position feedback without traditional mechanical sensing contact.
How fast is the ES9254 II?
At 8.4V it reaches 0.035 sec/60° with up to 7.5 kgf·cm torque. Its dedicated RC chip is designed to respond about twice as fast as conventional chips.
Is it suitable for outdoor helicopter flying?
Yes. Metal gears, an all-metal housing and IP67 protection help protect the servo in outdoor RC helicopter operating conditions.
What voltage range does the ES9254 II support?
It supports 6.0V to 8.4V. Speed ranges from 0.05 sec/60° at 6.0V to 0.035 sec/60° at 8.4V, while maximum torque ranges from 5.0 to 7.5 kgf·cm.
