Graupner HoTT GR-12S receiver (Graupner 33505)
The GR-12S 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.
Failsafe, hold, OFF, and standard (channel 1 failsafe; all others hold) programmable.
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
