ACE RC BLC-40€ Brushless ESC
1. High power, high efficiency, low weight, compact size.
2. Automatic cut-off, auto neutral setting and auto
detection of all types and number of cells.
3. Perfect design for direct drive applications. The motor will
respond to throttle input & accelerate instantly. The ESC
features immediate motor power cut-off function when
the battery voltage drops. Move the throttle to the
neutral position & then push throttle forwards, the car
will run again. Repeat above actions until the voltage has
been dropped to its battery specific low cut-off voltage,
the motor will be then completely shut down.
4. Thermal protection - The motor will be intermittently
turned off when the temperature reaches around 95°C.
The use of the cooling fan is recommended.
5. Fail safe mode - While detecting any abnormal signals or
signal failure between transmitter & receiver for about 2
seconds, the controller will cut off the motor power
automatically. Once the signal gets back to normal, the
system will be turned on automatically again.
6. ESC Set-up card- This card can be helpful for changing
ESC's setting in a user-friendly way. For more
information, please see the instruction manual of the
ESC Setting Card.

1. Install the ESC according to the diagram shown above.
Switch on the transmitter first, and then switch on the
ESC power.
2. Once the ESC is switched on, it will denote a series sound
indicating the ESC is actuating. Adjust the throttle trim
to get the best neutral position. When neutral is set, it
will be denoted by another confirmation sound. If it fails
to set up neutral, the confirmation sound will not be
heard. In such a case where neutral is unable to be set,
re-do & re-check the system again starting from Step1 of
these instructions. This ESC is applicable to transmitters
with either 50/50 or 70/30 throttle/brake movement
range.
3. Confirm that the throttle forward direction coincides with
the ESC forward direction. Lift the car off its wheels.
Move the throttle forward and watch the wheel's rotation
direction, then move the throttle backwards and see if
the system brakes.
4. If the wheels' movement coincides with the throttle input
then the setting is correct.
If the movement is opposite
then switch off the ESC, change the setting on the
transmitter's throttle reversing switch, and go back to
Step 2.
5. Motor rotation direction - Slowly apply throttle to check if
the motor is rotating in the correct direction you expect.
To reverse the direction of the motor, switch any two of
the motor wires. Note: Do not reverse the battery
wire connections! Reversing the battery polarity
will permanently damage the ESC.
6. For the first trial run, start with a smaller gear motor for
2~3 minutes then monitor the temperatures of both the
ESC & motor. If both temperatures are similar to each
other, they are at good match. The gear ratio can then
be properly adjusted to the desired optimum ratio
depending on the type of car and track. However, it is
very important to always keep both temperatures under
95 °C, when selecting a gear ratio. A higher gear ratio
(larger pinion or smaller spur gear) will increase the
system temperature. Running the system at increased
temperatures will cause demagnetization of the motor
will start to result in a dramatic drop of motor efficiency.
7. It is ok to replace a higher gear ratio or a higher KV
motor if the temperature is kept under 80 °C but it
should be done in accordance to the instructions in Step
6. Start from a lower ratio then incrementally adjust
higher. Battery selection is also an important
consideration. Changing to a higher voltage battery will
require a lower KV motor and/or a lower gear ratio,
unless the original motor has a low enough KV rating to
begin with. The ESC will be burn out if the motor and
gear ratio does not match the input voltage properly. See
the example below showing how battery voltage affects
power output.
Input 7.2V, internal resitance 0.189---40A
(V/R=I
7.2/0.18=40A)
Input11.1V, internal resistance 0.18Q---61.6A
(V/R=I
11.1/0.18=61.6A)
E Driving forward
With the car at rest, move the throttle full forward and the
car will be in so-called "Hard Start" mode with a very fast
initial start without any delay on accelerating. The car will
reach the full speed from still in the shortest time. The
motor perfectly responds to the signal of acceleration
instantly.
(User can use the ESC setting card to set the level of
forward driving power, there are 4 modes to select from.
Default has been set in standard mode. For more
information, please see the instruction of ESC setting card.)
E Braking
The brakes will be actuated by reversing the throttle
direction while driving forwards. Braking power is
modulated by the amount of throttle input in the
brake/reverse direction. The maximum
braking power can
be adjusted using the transmitter EPA. (Depends on the
functions of the chosen transmitter, for details please
consult the instructions of your transmitter). The brake
efficiency will be also influenced depending on whether the
reversing function is switched on. See section "Driving
backwards".
E Driving backwards
Reverse is actuated by moving the throttle to the
brake/reverse direction after the car has come to a stop.
Reverse speed is modulated by the amount of throttle input
in the brake/reverse direction. While the car is still moving
forward, the brakes will be actuated when the throttle is
moved in the brake/reverse direction. Reverse will not
engage until the wheels have come to a stop.
(User can use the ESC setting card to set the level of
driving power, there are 3 modes to select from. Default
has been set in standard mode. For more information,
please see the instruction of ESC setting card.)
m Over temperature protection
Motor will be intermittently turned off if the temperature
reaches around 95°C. The cooling fan is recommended
in
order to enhance the ESC ventilation.
1. Once the battery pack is connected, handle the model
with extreme care; make sure body parts and clothing
are clear of all rotating parts.
2. Be sure to turn off the ESC power before plugging /
un-plugging the setting card
3. Connect the battery pack just before driving and
disconnect immediately after driving. When the car
is not in use, do not leave the battery connected or
unattended over long periods of time.
4. Always make sure you are connecting the ESC to a
proper power source that has the correct voltage &
polarity. Incorrect voltages or reversed polarity will
damage the ESC.
5. Avoid touching the ESC heat sink or motor casing right
after operation to prevent burns
