GR-12 HoTT - 2.4 GHz receiver

The GR-12 provides real-time bi-directional data transmission of critical system health data like temperatures, receiver voltage and signal strength using the Graupner HoTT protocol providing you with telemetry information you need for a safe and secure flight. The built-in program mixers allow increased flexibility in flight precision and function.

Features:

• Up to 75 channel hopping for extreme operating reliability and immunity to external interference
• Compact and lightweight
• Front-load servo connections for easier installation in small airframes
• Digital output for SUMD, SUMDV3, SUMO, SUMI, SBUS signal providing connectivity to other vendors flight controllers and secondary satellite for other Graupner HoTT receivers
• Selectable frame rate of 10ms or 20ms for digital or analog servos
• Fail Safe and Hold function
• Low power consumption
• Wide voltage ranges from 3.6V to 8.4V
• Built-in telemetry for temperatures, receiver voltage and receiver strength monitoring
• 5 built-in program mixers
