Instruction Manual
a. Install
The ESC into your model:
Mount the speed controller into the model, and isolate it from vibration
and shock, and make sure ventilation of the
speed controller is surfficient and directly by outside airflow, otherwise
it may result in overheat of the speed controller.
b.
Connection & power up procedurers:
*Just connect the three wires of the brushless motor to the three wires of
the ESC, in case the motor runs in a wrong
direction, you can reverse the motor by swapping any two connections of the
3 wires to the motor.
1. Connect the main power pack to the speed controller, and make sure the
connection is sound .
2. Switch on the transmitter, and check the throttle channel settings are
+/- 100% (for computer radios).
3. For the types without BEC function, switch on the power to receiver or
use an external BEC to power the receiver.
4. Switch on the speed controller.
You should hear a ˉbeepˇ. (* Before hearing aˉbeepˇ, the throttle stick
must not be moved).
If you do not hear a ˉbeepˇ, switch off the speed controller, disconnect the
power connectors, wait for 5 seconds and
repeat the procedures of connecting and switching on.
If you still do not hear a beepˇ, check the following:
- Is the JR connector plugged into the throttle channel?
- Is the throttle stick in full closed position (low end)?
- Is the throttle channel in ˉnormalˇ position & not reversed? Futaba
transmitters should have channel 3 reversed for
correct operation of the speed controller.
You will hear the ˉbeepˇ when first switching on the controller only. When
you switch off the speed controller without
disconnecting the power pack, you will not hear the beep after next
switching on.
The speed controller will adjust the throttle range automatically.
c. Brake
mode:
The speed controller is supplied with the ˉbrakeˇ activated. If you want to
turn off the brake, do the following:
- Switch on the transmitter and move the stick to full throttle.
- Connect the main power pack and turn on the receiver switch (if used).
- Wait 5 seconds.
- After 5 seconds you will hear 4 tones.
- Swiftly move the throttle stick to the closed position; you will hear two
ˉbeepsˇ.
- The brake is now turned off.
The brake setting will not change after disconnecting the main power pack.
When turning on the speed controller with
the brake active, you will always hear one ˉbeepˇ. When the brake is turned
off you will hear two ˉbeepsˇ. If you want
to activate the brake again, repeat the procedure.
d.Timing
modes:
There are two timing options for these speed controllers.
-Soft timing: for 2,4,6, pole motors like Mini AC, Kontronik, Hacker etc. Do
not use hard timing with 2-pole motors
-Hard timing: only for 6 and more poles motors , outrunner motors should use
Hard timing.
The Speed controllers are supplied with soft timing.
To change the timing mode:
Switch on the transmitter and move the stick to full throttle.
- Connect the main power pack and turn on the receiver switch (OPTO
controllers) and wait 5 seconds
- After 5 seconds you will hear 4 ¨beeps〃
After a further 5 seconds you will hear 5 ¨beeps〃 for soft timing
- OR 5 double ¨beeps〃 for hard timing
- The required timing is set by moving the throttle stick to the closed
throttle position.
- The new timing is confirmed by a single bleep (brake on) or a double
¨beep〃 (brake off)
The timing setting will not change after disconnecting the main power pack.
Timing monitor (if you want to know what the current timing mode is).
After the first ¨beep〃(s) wait 5seconds (keep the throttle at the closed
position).
The controller (motor) gives 5 single beeps for soft timing or 5 double
beeps for hard timing
It is possible to interrupt this beeping at any time by moving the throttle
stick forward.
e. Cut-off
protection:
The Eagle series controllers have automatic cut off with auto detection for
the number and type of cells. This circuit
provides the correct cut off for all types and number of cells.
If the brake is on, the low voltage motor cut-off is sudden (controllers
with BEC) leaving the remaining capacity for a safe
landing (soarer mode). If the brake is not active (aerobatic mode or ¨opto〃
controllers) the ESC automatically provides a
gradual low voltage motor cut-off. A gradual low voltage motor cut-off is
preferable with an aerobatic model to avoid a
sudden loss of power which would inevitably happen down wind and at low
altitude.
f. Overheat protection:
Temperature overload protection is built into the speed controller which
will turn off the motor when the temperature
reaches 110.
Warning:
*Once the main power pack is connected, handle the model with extreme care,
ensure that everyone is well clear off the
propeller at all times. Rotating propellers are extremely dangerous!
*Take care to ensure the correct polarity of NiCd, NiMH or Li-XX power
packs. Wrong polarity may result in severe
damage of your speed controller.
* Connect the main power pack just before flight and disconnect it
immediately after landing.
*The speed controller switch does not isolate the main power pack.

Program Card for ESC
Specifications:
Dimension: 41 x 42.5 mm
Weight: 10g
Features:
With Fdragon’ s Program Card, you can easily set the programming
value of Electronic Speed Controller (ESC) for brushless motor. Now
you can just forget the complicated and boring programming method with
the throttle stick.
The Program Card has a friendly user interface and is easy to use.
It is as small as a business card, so you could put it in your pocket
when you are on field.
