EMAX ES09A Dual-Bearing Swash Servo for 450 Helicopters

The EMAX ES09A is a dedicated analog swashplate servo engineered specifically for 450-class RC helicopters. Built with a dual-bearing output shaft, it delivers precise control and smooth operation for cyclic linkages, minimising mechanical slop to ensure stable hovering and accurate forward flight response.

Key features

• Tailored control response and travel range designed directly for 450-size helicopter swashplates.
• Dual-bearing output shaft maintains gear alignment and reduces long-term wear.
• Fast transit speeds of 0.08 sec/60° at 6.0V provide crisp cyclic pitch control.
• Lightweight plastic gear train keeps the overall servo weight below 15 grams.
