Overview

The GR-12 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.

Functions with SMART-BOX:

• 3 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
• Limitation and reversal of servo travels also possible in receiver
• Failsafe, hold, and OFF programmable individually for the servo channels
• Warning thresholds programmable for undervoltage, excess temperature, and low temperature
• Servo test function

Features

• 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.
