YGE Opto 255 Brushless ESC
The YGE Opto 255 is a high-end speed controller designed for demanding RC applications such as helicopters, gliders, and large aerobatic aircraft. This ESC does not feature an integrated BEC and uses an optocoupler for maximum signal isolation and safety. It's best used with a separate BEC (e.g. JETImodel MAX BEC 2D Plus EX) or a JETI Central Box system for optimal reliability.
Broad Compatibility
The YGE Opto 255 works seamlessly with:
- Analog and digital servos
- High-voltage servos (via Central Box 100, 210, 220, 310, 320, 400)
- JETI REX receivers (telemetry output on ports E1 and E2)
- EXT port and expanders (requires YGE TexY)
6 Pre-Programmed Operating Modes
Quick setup is made possible with six pre-defined flight modes. All key parameters are automatically configured via your transmitter stick:
- Mode 1: External governor
- Mode 2: Governor
- Mode 3: Governor Store
- Mode 4: Powered flight with brake (gliders)
- Mode 5: Powered flight without brake
- Mode 6: Powered flight with acro brake
Advanced Features
- Super-soft sine wave motor startup
- Automatic PWM frequency adjustment to match the motor
- Current limiter & intelligent overtemperature protection
- Bailout function for immediate motor restart during autorotation
- EMK braking & adjustable F3A brake during flight
- Flight data logging: min/max values (e.g. current) can be reviewed with PC software
Extensive Telemetry Support
Compatible telemetry systems include:
- JETI ExBUS (with direct transmitter access via JetiBox)
- JETI EX (via YGE TexY)
- Spirit, Graupner HoTT V4, Multiplex Sensor BUS V2
- Mikado, JR PROPO, Futaba, FrSky, Spektrum, Core (via YGE TexY)
Programming & Updates
Basic setup is done via transmitter using the pre-set modes. For more advanced settings, the YGE Connect software (PC) allows:
- Fine-tuning of startup, timing, braking, and telemetry protocols
- Reading flight logs and error messages
- Saving and loading custom configurations
- Online firmware updates
A USB adapter is required for PC connection.
