The GR-12SH receiver can control up to 6 servos

With the 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. Without additional sensor systems, the parameters receiver voltage and temperature, as well as signal strength are transmitted.

• The use of up to 75 channels ensures extreme 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.
• Two LEDs signal operating status.
• The sizes and weights have been reduced.
• Receiver input sensitivity and thus the range have been increased further.
• Servo connections in the front panel.
• Failsafe, hold, OFF, and standard (channel 1 failsafe; all others hold) programmable.
• PPM Sum 8 cannels
• Output SH conector
• The first 3 channels are transmitted at an interval of 0.1 ms. Channels 4 - 6 are transmitted after half the period also at intervals of 0.1 ms so that control is as precise as possible and the power peaks of the servos nevertheless do not occur exactly simultaneously.
• Periods of 10 ms or 20 ms can be programmed
• 5 free mixers
• Internal voltage measurement or external voltage measurement up to 25.2 V with a simple voltage divider on channel 5.
• Motor connection for channel 1 for brushed motors with a maximum continuous power consumption of 2 A.
• Motor connection for channel
