DIMENSIONS:
39x28x8 mm
WEIGHT
9.3 grams (including wires and connectors)
CONNECTIONS:
The receiver has following connections:
- Battery connector – connect to your power battery using JST connector.
- 4 1.5mm Molex connectors for servos
S1 – Ailerons
S2 – Elevator
S3 – Rudder
S4 – Gear (can be programmed as second Aileron or Flaps or any other output needed)
- 1 1.5mm Molex connector for PC connection via UART to USB adapter
- 3 leads to connect brushless motor (black thick wires).
BUTTONS:
The receiver has one button which is used for firmware update. (Upd)
LED-S:
The receiver has two LED-s – Red and Blue.
Blue LED indicates receiver functionality
- Binding state – blinks rapidly
- Signal presence state – solid ON
- No signal – LED is OFF
Red LED indicates stabilizer functionality
- After the device is turned ON Red LED is ON indicating that the stabilizer is not ready yet. After receiver and stabilizer are successfully
initialized Red LED will go OFF.
- The device is ARMED – solid ON
- If dangerous angle of the plane is detected (more than 30 degree to the horizon on bank or pan) the LED will start blinking slowly indicating
that it is not safe to start motor. Arming will not be possible in these conditions. You need to bring your plane in the straight upright position to
be able to arm motor,
BINDING:

Page 3 of 9
The receiver will work with any DSMx/DSM2 compatible transmitter or Tx module.
There is two ways to initiate binding procedure:
1. Manual binding by power ON with pins 2 and 3 on UART connector shortened;
2. Autobind - after 30 seconds of no known signal from transmitter received the device will initiate binding procedure. If the receiver didn’t see
any transmitter in binding mode nearby for 30 seconds, the receiver will turn binding mode off for safety reasons.
The receiver indicates binding mode by rapid blinking of blue LED (3-4Hz). Follow the instructions of your transmitter to initiate its binding.
During binding blue LED will change the pattern of binding and if the binding was successful blue LED will become solid ON.
MOUNTING STABILIZER IN THE PLANE:
Mount stabilizer in the plane on flat solid surface parallel to the wings and in line with fuselage, antennas facing front. Place stabilizer close to
the center of gravity of the plane. It will make the stabilizer work better. Use double sided foam supplied with stabilizer or similar. Try to
minimize vibrations of the plane(propeller better to be balanced) because vibrations will affect the stabilizer performance.
STABILIZER:
• 4 channels PWM output to servos
• 3 mode of stabilizer
- Acro Pro mode - rates, no autolevel
- Advanced mode - autolevel mode with acro capability
- Beginner mode – “SAFE” mode, envelope. User can limit the maximum angle of pitch and roll.
• Bypass mode – for experienced pilots and aircraft tuning – no stabilization, direct control of aircraft
• 3 aircraft schemes
- T-Tail (Classical)
- V-Tail -
- Delta (Flying wing)
The stabilizer can be connected to the PC using USB-UART adapter (sold separately)
Settings for UART are 115200, N, 1.
A PC software can be downloaded from “Files” section from the Hobbyking Web site.
Using PC software is similar to most of the flight control PC apps and self-explanatory.
Using PC software you can:
• Tune PID-s for different aircrafts with typical tuning presets and mixes for T-tail, V-Tail, Delta;
• By various servo assignment and mixes set up the aircraft with virtually any servo position and orientation;
• Set various aspects of the stabilizer behavior, assign channels for flight modes and much more.
• Save and restore set ups to keep different configurations for different aircrafts
SETTINGS VIA GUI :
Please note: GUI outlook is for reference only. It will be changed in commercial release.
FIRMWARE UPGRADES:
• Firmware upgrades are done via UART interface and GUI. Pre

parameters you want to edit. Click Enter again. Now you can navigate between P, I and D parameters. Click enter again.
The edited parameter will start blinking. Use roller to change the value. When value is changed press Enter again and
exit the value changing mode. You can navigate to another parameter and change their values if you need. After
changes are done push roller UP several times to exit to upper and upper levels and finally exit. The window will pop up
asking if you want to save changes. Choose what you want to do and click Enter on the roller. The changes will be
transferred to the flight control to save.
Note: when some parameters are changed but not saved yet, the info string appears: “p r m chng” telling you that
parameters are changed but still not stored in flight control.

Beginner sens – sensitivity for Beginner mode. If sensitivity is too high the model can start oscillating. Lower sensitivity
in this case.
Adv nce sens – sensitivity for Advanced mode. If sensitivity is too high the model can start oscillating. Lower sensitivity
in this case.
Stick p r m – the parameter how far from the center a control stick needs to be to disable autolevel in advanced mode.
The value range is 0…255 from stick in middle to the extreme position. This parameter allows to make rolls and loops in
Advanced mode.

"F-Wing", "Classic", "V-Tail"
Min thr – Minimum throttle for ESC when the throttle stick is low
M x thr – Maximum throttle for ESC when the throttle stick is high
Min comm nd – Minimum throttle for ESC during initial calibration on start.
Ple se note: If the model type is changed, all previous settings will be erased and set to default values. You will need to
set them again according to your needs.
7 P ge 7. Accelerometer c libr tion
To calibrate an accelerometer:
1. Place the plane horizontally in exact position as it is supposed to be during the flight straight. The plane should stay
still and stable in this position. Do it indoor because wind will affect calibration settings.
2. Enter Calibration menu. Confirm to start calibration process.
Please note that during calibration the stabilizer will be disconnected from the Programming Card for short period of
time. Do not touch or move your plane at this moment.
After calibrating is finished, the connection with the Programming Card will be restored and the message «ACC ok» will
appear on the top side of the screen.

.
Program Card can act as Transmitter when it works with the stabilizer. In this mode Program Card outputs channel
values to the receiver imitating transmitter. In this mode you can change these values as if you would do this using. You
can set values on the each servo output. This is very useful for mechanical setup of planes for example.
