Overview
The EMAX ES3302 is a mini metal gear analog servo designed for RC airplane glider installations where a thin 9 mm width and low weight are required. It operates on 4.8–6.0 V and supports counter-clockwise standard direction with a pulse traveling range of 1500 to 1900 usec.
Key Features
- Ultra-thin 9 mm width design, suitable for gliders
- Special engineering plastics construction for a tough gear set and case
- NOBLE potentiometer for high accuracy and coherence
- Dual-bearing design for low backlash and long-term smoothness
