HITEC HFP-25 User Manual
Rt t
Welcome to the world of high performance servo technology.
Using your new servo tester and Hitec digital servo programmer, it will allow you to program the
functions of Hitec digital servos.
Additionally you can test any brand of transmitter for the pulse sent to the receiver and any servo
for voltage and proper movement.
HFP-25 is made for more affordable but it follows in the previous models great features.
This manual is split into two sections, the first being the Hitec digital servo programming section,
followed by the information on how to test any brand of servos.
Powering the HFP-25
- HFP-25 uses 4 cell 4.8V NiMh rechargeable battery pack to power the test and programming functions.
(The rechargeable battery’s capacity should be more than 1300mA for optimal operation)
- HFP-25 does NOT support charging port. Therefore, remove the battery from HFP-25 and charge
it directly using any peak charger capable of charging 4 cell 4.8V at about 0.6A-1.0A. (See pic.1)
(Hitec RX NiMh battery pack : #54117 or 54121)
- Pay close attention to the POLARITY of the battery when it is inserted to the HFP-25. (See pic.2)
Pulse Data
All Hitec servos require 3-5V peak-to-peak square wave pulse.
Hitec digital servos require 0.8-5V peak-to-peak square wave pulse.
Pulse duration is from 900
Ɇs to 2100Ɇs with 1500Ɇs as center.
The pulse refreshes at 50Hz (20ms).
General Hitec Servo Information
Voltage Range
Most of Hitec Servos can be operated within a 4.8V-6.0V range.
The HS-45, HS-50 and some feather sized servos operate exclusively with 4 Ni-Cd cells (4.8 volt).
Wire Color Meanings
On all Hitec servo wires are in three different colors: Black, Red, and Yellow.
The Black wire is 'ground', the Red wire (center) is 'power' and the yellow wire is 'signal'.
Direction of Rotation
All Hitec servos set to rotate Clockwise (CW) as factory default.
Section One: Hitec Digital Servo Programming
Hitec Digital Servo General Information
Hitec digital servos can be used "out of the box" without any complicated programming procedure.
Also, Hitec expanded the capability of our digital servos to include the ability to program your own
unique performance specification parameters.
Many of you will have modern computer radios that will allow you to program most of these
functions; however, some features, like dead band width, are only programmable by using
the servo tester/programmer device.

The following is the function flow chart of the Tester/Programmers features;
This instruction manual is formatted to follow the tester/programmer software flow.
To access the features listed below; the user would turn on the device and scroll through the
screens using the UP/R or DN/R button.

Low Battery Warning
- If the programmer’s voltage becomes below 4 volts, the programmer’s LCD screen will flash
“LOW BATT”. Programming should be avoided at low voltage warning status.
