Instructions of 30A Brushless Speed controllers
Features / Specifications:
1. These
types of speed controllers especially designed to offer high power and high
efficiency combined with low weight and compact dimensions.
2.
Automatic cut – off and auto detection of all types and number of cells.
3. Brake set to non-active –
Factory default setting
It is defined
as a Hard start mode. Start motor quickly and be able to response to
acceleration instantly. It takes the least time for motor to reach its full
speed. This mode is suitable for these models, such as helicopter or fan-fly,
which require fast response to acceleration. Under this mode, at the termination
of a powered flight, the controllers will reduce the current drain to the motor
progressively so providing ample power to the BEC, receiver for positive
control. There is no immediate cut off but a rather drizzle down of propeller
speed and motor response. The player will not lose the power at one moment The
system will provide a very good soft landing before the cut off of the system
power. ( The system power will be cut off when the battery voltage is down to
65% of the full battery charge voltage).
4. Brake
set to active
It is defined
a Soft start mode. Start slowly & steadily, without any intermittence at full
speed & with a very solid brake reaction when actuated. It is suitable for
glider / sailplane or airplanes with propeller foldable & collectable. The cut
off is sharp. The system will cut off motor power and actuate the brake at one
moment when the Power of the battery is lower than 65% of the full battery
charge voltage.
5. Over temperature protection
- Motor to be intermittently turned off when the temperature reaches 105°
centigrade.
6. Low speed control – Be
able to let motor running steadily at very low speed.
7. Fail
safe mode - once there is
any abnormal signal or signal fail between transmitter & receiver being detected
for about 2 seconds, the controller will cut off the motor power automatically.
Once the signals get back to normal, the system will auto-turn on again
automatically.
Once the signals get back to
normal, the system will auto-turn on again automatically.

Note: When
using fast servos or digital servos, it is necessary to reduce the number of
servos by one to two.
Operating Instructions:
1. Connect the output wires of the
Speed Controller to the motor.
2.
Plug the connector ( JR,
Futaba, etc ) into the receiver throttle channel.
3.
Ventilation
- Mount the speed
controller in the model at proper position with good ventilation & so as to
isolate it from vibration and shock. Allow space around it for cooling. Make
sure that there is sufficient cooling of the motor and speed controller by the
ducting air through adequate
cooling holes from the outside airflow. Ventilation is extremely important for
those use voltage source over 12 V.
4.
Assure throttle stick at correct forward or reverse direction -
Switch on the transmitter, move the throttle stick to the low speed or brake
position. Switch on the power to receiver. If there is a music of “ Do Re Mi “,
the transmitter is set at the correct forward / reverse direction. Otherwise,
after 3 ~ 4 seconds, it will sound a series beeps (- - - ) instead of tones of
“Do Re Mi”. To correct this mis-direction problem, please reverse the reverse
selection switch of the throttle stick & re-start the above process again. About
two seconds after “ Do Re Mi “, there will be a tone of “DaLa “ ( Brake
non-activated) or “ DaLa DaLa” ( Brake activated ). These prompt tones are
indicating the power on safe is properly relieved.
5. Motor rotating direction
- Slowly move the throttle stick for acceleration & make sure the
motor is rotating in the right orientation. Exchanging any two of motor wires
will change the motor direction accordingly. ( Warning:
Be sure not to exchange the battery wires in order to reverse the motor
direction. It will permanently damage the speed controller)
6. Brake
setting
The speed controller is supplied
with the ‘brake’ non-activated. If you want to turn on the brake, do the
following:
-
Switch on the transmitter and move the throttle stick to full speed.
-
Connect the battery pack and turn on the receiver switch ( if used ).
-
Wait 3~4 seconds.
-
You will hear 3 tones of “ Do Do Do “.
-
Right after above tones of “ Do Do Do “, move the throttle stick fast to
the low speed position immediately, you will hear two tones of “ Dala Dala “.
-
The ‘brake’ is now turned on.
7.
Enable or disable the brake
- The brake setting is
memorized, that means it will not be changed after disconnecting the battery
pack. When turning on the speed controller with the brake ‘non - active’, there
will always be one ‘ Dala’ tone after tone of “ Do Re Mi “. When the brake is
set active, there will be a double ‘Dala Dala’ tone after tone of “ Do Re Mi “.
If you want to change the brake status, repeat the above brake setting
procedure.
8.
Be sure to move the throttle stick
to the brake or low speed position to relieve the power on safe every time when
switch on the speed controller. Prior to start the motor, be sure to confirm the
system feed back with the correct prompt tones.
9.
Warning
-
Once the battery pack is
connected, handle the model with extreme care – Ensure
that you
are well clear of the propeller at all times. Rotating propellers are extremely
dangerous!
- Connect
the battery pack just before flight and disconnect it immediately after landing.
- Do not connect speed controller
to just ‘any’ kind of power source. Take care to ensure the right
Polarity of NiCd, NiMH or
LI-polymer power packs. When using the wrong polarity, the speed controller will
be severely
damaged.
