HGM SST +T BB MG Speed Racing HV BL Digital Telemetry Servo

P/N: S4086


Designed for the needs of surface drivers who need performance and reliability without compromise, the Graupner HGM SST +T Speed High-Voltage Brushless is a racing servo ideally suited for 1:8 or 1:10 nitro track type models.

The new +T version of the HGM SST +T features built in telemetry to monitor servo performance under various conditions of load. Also, when using the over the air setup interface on our X-8N or X-8E surface radios you will be able to fine tune many servo setting without the need of any special program boxes or computer.

The HGM +T series are digital servos optimized for high voltage (7.4V) and designed around a high performance brushless motor, precision cut metal gears, metal heats sink and are water resistance making them the perfect workhorse under demanding track conditions.

HGM +T servos provide speed and holding power with low dead band technology for extra precision. HGM +T servos can be programmed with any of our X-8N or X-8E surface radios when connected to a GR-8 HoTT receiver.
