HiTEC Servo Explainer

1. Product Codes

1.1 HiTEC Series Type Identification X(XX)-YYYYZZ

HS = HiTEC Servo

HSB = HiTEC Servo Brushless

HSG = HiTEC Servo Gyro

HSR = HiTEC Servo Robotic (Continous Rotation)

HLS = HiTEC Servo Linear

HS-M = HiTEC Servo Magnetic Encoder

D = HiTEC Servo 32 bit digital

DB = HiTEC Servo 32 bit digital

Brushless MD = HiTEC Servo Magnetic Encoder

32 bit digital MS = MULTIPLEX Servo

1.2 HiTEC Number Convention Key X(XX)-YYY(Y)Z

3 digits = analogue servos

The 3rd digit roughly indicates the servo class
0XX (sub)-micro servos < 13 mm width
1XX wing servo
2XX Compact servos 13 – 18 mm
3XX 20 mm low-cost series
4XX 20 mm standard
6XX 20 mm Premium
7XX Quarter-Scale (29 mm)
8XX Giant-Scale (30 mm)

4-digit = digital servos

5XXX are 1st generation digital servos
7XXX are 2nd generation digital servos with extended programming options
M before 7XXX Magnetic encoder servos without potentiometer

2. Programming Options

Analogue servos (HiTEC)

Not programmable D-series** and HSB-series
Setting the centre and end points (180° function)
Setting the direction of rotation (clockwise/counter-clockwise)
Assigning a servo identification number
Setting the dead zone (electronic ‘play’)
Setting the speed (servo can be made slower)
Setting the soft start (servo runs slowly to its neutral position when first switched on)
Setting the fail-safe function
Setting the Smart Sense function (prevents the servos from ‘shaking’ in the rest position)
Setting the overload protection (servo becomes ‘soft’ if overloaded for too long, preventing it from burning out in the worst case)
Reset to factory settings

Some functions are only available with recent D-series servos. 5XXX and 7XXX series (HiTEC):

Setting the centre and end points (180° function)
Setting the direction of rotation (clockwise/counterclockwise)
Setting the dead zone (electronic ‘play’)
Setting the speed (servo can be made slower)
Setting the fail-safe function
Setting the resolution
Setting the overload protection (servo becomes ‘soft’ if overloaded for too long, this prevents burn-out in the worst case)
Resetting to factory settings
