The GR-12 receiver can control up to 6 servos
With GRAUPNER HoTT 2.4 GHz technology, the receiver has a new hopping telemetry transmission high-frequency unit with state-of-the-art components and the latest software. Parameters for receiver supply voltage, receiver temperature and signal strength are transmitted without any additional sensors.

• The use of up to 75 channels ensuresextreme operating reliability and immunity to external interference.
• The broad reception voltage range of 3.6 V - 8.4 V (functional to 2.5 V) ensures full functionality even when voltage fluctuates.
• The green LED signals the operating status.
• Size and weight have been reduced.
• The receiver input sensitivity and thus the range have been increased further.
• Fail-safe, hold, OFF and standard (channel 1 fail-safe; all others hold) programmable

• 5 mixers programmable
• Linear, degressive, and exponential programming of servo curves
• Telemetry connection instead of a servo possible on channel 5
• SUM signal programmable at the output of the highest channel (e.g. for V-Stabi, Microbeast, Quadrocopter, wireless pupil function with mc-19/22 HoTT, flight simulators)
• Limitation and reversal of servo travels also possible in receiver
• Fail-safe, hold and OFF programmable individually for the servo channels
• Warning thresholds can be programmed for undervoltage, overtemperature and undertemperature
• Servo test function
