Losi LOSB9504 - Manual

EN
Be careful, some transmitters offer better resolution
than others. If your ESC will not respond to “Neutral”
throttle, make this setting larger.
Setting 1: Large—0.1500 ms
Setting 2: Normal—0.1000 ms (Default)
Setting 3: Small—0.0750 ms
Setting 4: Very Small—0.0500 ms
Setting 5: Smallest—0.0250 ms
7. Cutoff Voltage
Sets the voltage at which the ESC lowers or removes
power to the motor in order to either keep the battery
at a safe minimum voltage (Lithium Polymer cells) or
the radio system working reliably (NiCad/NiMH cells).
Setting 1: None
Does not cut off or limit the motor due to low
voltage. Do not use with any Lithium Polymer packs.
Applications: Any racing or bashing situation with
6–8 cell NiCad or NiMH packs.
Use this setting ONLY with NiCad or NiMH packs.
With continued driving, the radio system may
eventually cease to deliver pulses to the servo and
ESC, potentially causing the vehicle to lose control.
You will irreversibly damage Lithium Polymer packs
with this setting.
Setting 2: Auto-LiPo (Default)
This setting automatically detects the number of LiPo
cells you have plugged in. It will automatically set the
cut-off to 3.2 volts per cell. It will beep the number
of cells in your LiPo pack between the initialization
tones and the arming tones on initial power up the
controller.
Setting 3: 5V
Cuts off/limits the motor speed/acceleration when the
pack gets down to 5 volts. A good setting for racing
or bashing in any vehicle using 8–12 NiMH or NiCad
packs.
Setting 4: 6V
Cuts off/limits acceleration when the pack gets down
to 6 volts.
A MUST USE setting for 2-cell (7.4V) Lithium Polymer
packs. You will irreversibly damage your packs using
a lower cutoff voltage.
Setting 5: 9V
Cuts off/limits acceleration when the pack gets down
to 9 volts.
A MUST USE setting for 3-cell (11.1V) Lithium
Polymer packs. You will irreversibly damage your
packs using a lower cutoff voltage.
Setting 6: 12V
Cuts off/limits acceleration when the pack gets down
to 12 volts.
A MUST USE setting for 4-cell (14.8V) Lithium
Polymer packs. You will irreversibly damage your
packs using a lower cutoff voltage. Use of a 4-cell
LiPo pack is covered under warranty ONLY on
Monster Max ESCs.
8. Motor Timing
Advancing the timing on an electric motor can have
varying effects. Lowering the timing advance will
reduce the amp draw, increase runtime, reduce motor/
battery temperature, and may slightly reduce top speed
and punch. Raising the timing advance will increase
amp draw, decrease runtime, increase motor/battery
temperature, and may slightly increase top speed and
punch.
If you are after maximum top speed, it’s better to “gear
up” to get it rather than advance the timing too far.
For brushed motors, always keep this setting on
NORMAL and use the end bell of the motor to “tweak”
it to max RPM per the motor’s instructions.
Setting 1: Lowest
A maximum efficiency setting giving long runtimes
and cooler motor temps. Very useful with high Kv
(low turn) motors to increase motor life and reduce
motor/battery temperatures.
Setting 2: Normal (Default)
The best mix of speed, punch and efficiency for all
motors.
Setting 3: Highest
Increases amp draw, reduces runtimes, increases
motor/battery temperatures and may increase top
speed/punch slightly.
Use with care and monitor motor and battery temps
often. DO NOT use any setting above “normal” with
6000Kv or higher motors.
9. Motor Type
This setting sets which type of motor you will be
using with the Losi ESC. The ESC may be damaged if
this setting does not match the motor type/hook-up
method in the car, and this damage is not covered
under warranty.
Setting 1: Brushless (Default)
(See Brushless Motor Setup section) Uses all three of
the ESC motor wires connected to all three of the
brushless motor wires. If the motor spins the wrong
way with forward throttle, swap any two of the wires
to get the correct direction.
Setting 2: Brushed Reversing
(See Reversing Brushed Motor Setup section) Uses the
Red and Black ESC motor wires to connect to the (+)
and (-) side of the brushed motor. If the motor spins
in the wrong direction with forward throttle, reverse
the motor wires for correct motor direction.
Setting 3: Brushed High Power
(See High Power Brushed Motor Setup section)
Connect all three of the ESC motor wires to the
negative (-) side of the motor. You can either use a
“Y” harness from the ESC battery input positive wire
to connect to both the battery and the positive side
of the motor, or use a single wire from the positive
ESC input to the positive battery pole and then
continue to the positive (+) side of the motor.
Troubleshooting
If you’re still having difficulties with your Losi ESC after
trying the suggestions offered here, please contact Losi
Service Center at the e-mail or phone number listed
below.
Problem: My Losi ESC may or may not arm, but it will
not calibrate to my transmitter.
Solution: Most calibration issues can be solved by
changing settings on the transmitter. Make sure you
have both your throttle and brake endpoints (called
EPA or ATV on your radio) on the throttle channel out
to between 100 to 120%. Make sure if you have a
Futaba or Futaba made transmitter to have the throttle
channel set to the reversed position.
Problem: My ESC calibrates for the full throttle and
full brake positions, but won’t calibrate to the neutral
throttle position (yellow LED keeps flashing).
Solution: Try moving the throttle trim one way, then
the other (usually towards the throttle side is best). If
your transmitter has a 50/50 and 70/30 setting for the
throttle, set it for 50/50 and retry calibration. Also, if
you have changed the dead band to a narrower band
you may want to try going back to the “normal”
setting.
Problem: My vehicle acts like it has “turbo lag” (poor
acceleration/punch for the first few feet or yards, and
then it “kicks in”).
Solution: Make sure you’re using high quality batteries
and a battery connector capable of high amp flow
(40–100 amps). This behavior is very typical of a battery
pack that is having difficulty providing the power your
vehicle/system requires for top performance.
Use copper bars to connect cells rather than welded
tabs. Copper bars have a much lower resistance.
Problem: My battery pack is plugged into the ESC and
nothing is working - no steering and no throttle.
Solution: Make sure the ESC’s receiver plug is plugged
into channel 2 on the receiver, and that it’s plugged in
with the correct orientation. Double check your solder
connections on the battery plug, and make sure the
battery is showing good voltage.

Power Wiring
Your ESC has motor connectors on the motor wires and
the battery input wires.
Proper polarity is essential. Make absolutely certain that
positive (+) connects to positive (+), and negative (-)
connects to negative (-) when you plug in your battery. If
reverse polarity is applied to your ESC from the battery,
it WILL damage your ESC. This WILL NOT be covered
under warranty.
Connections
Brushless Motor Wiring
For brushless motor connection, the three wires from
the ESC to the motor have no polarity. Connect the red,
white and black motor wires to the three wires coming
from the motor. If you are using a motor other than a
Losi LOSB9444 motor, you may need to either solder on
matching male bullet plugs to your motor, or solder the
ESC wires directly to the motor wires.
Since there is no polarity on the three ESC-to-motor
wires, do not worry about how you connect them
initially. You may find it necessary to swap two wires if
the motor runs in reverse. This will be explained later.

Radio Connection
Your Losi ESC plugs into the throttle channel of your
receiver. This is usually channel 2. Your Losi ESC provides
5 volts to the receiver to power the receiver and the
steering servo. No separate receiver battery is needed to
power the radio system.
Losi ESC receiver plugs are made to be used with any
receiver, so you will need to make sure the polarity is
correct. The signal wire is orange, the positive wire is red
and the negative is brown. Some radio systems use the
white for signal, red for positive and black for negative
color scheme. Check your receiver documentation for
correct connection polarity if it’s not marked. (Most
receivers use negative to the outside of the case and
signal towards the inside of the case.)
ESC Setup
ESC/Radio Calibration
Individual transmitter’s signals for neutral, full and full
brake vary. You must calibrate the ESC so that it will
operate most effectively with your transmitter. Anytime
the ESC is powered up with a new transmitter or with
different throttle channel settings, it will need to be
calibrated to “know” what the transmitter’s throttle
settings are. It will also need to be calibrated after
updating with new software via Castle Link.
If you are using a Futaba or Futaba OEM brand
transmitter, you will need to set the transmitter’s throttle
channel direction to the REVERSE (Rev) position. This is
either an external micro switch on the transmitter or an
option available within the computer programming of
the transmitter’s throttle channel.
Please start by zeroing out any throttle trim that you may
have set in your transmitter.
Don’t plug in the battery yet. Make sure that the battery
polarity and input polarity on the ESC are correct. Check
the on/off switch of the Losi ESC to make sure that it is
in the OFF position (“ON” is marked in small letters on
one side).
We recommend removing your pinion gear before
calibration as a safety precaution.
How to Calibrate the ESC
STEP 1: Start with the transmitter ON and the ESC
switched OFF and not connected to the battery.
STEP 2: Plug a battery into your Losi ESC.
STEP 3: Hold full throttle on the transmitter and turn
the ESC’s switch ON. Keep holding full throttle on the
transmitter. If all your connections are correct, you will
hear one multi-toned initialization “ring” from the motor
(all tones are played by the ESC vibrating the motor).
STEP 4: After a second or two, the green LED on the
ESC will blink rapidly and the motor will “ring” 4 times
rapidly in a row (accepting the full throttle endpoint).
After the green LED flashes and tones, the red LED on
the ESC will blink. At this point, the full throttle endpoint
has been set within the ESC and now it’s looking for the
full brake endpoint (red LED blinking).
STEP 5: Move the throttle trigger to the full brake
position and hold full brake. After a few seconds, the
red LED on the ESC will flash and ring 4 times rapidly
(accepting full brake endpoint).
STEP 6: After accepting the full brake endpoint, the
yellow LED on the ESC will blink. Relax the trigger to the
neutral position. The ESC will now ring 4 times and flash
the yellow LED rapidly to accept the neutral position.
After accepting the neutral position, the ESC will ring
twice and all the LEDs will flash. This is the arming tone
and LED indication that the ESC is now ARMED and the
car will respond to throttle inputs from your transmitter.
From this point on, when you connect the battery and
turn the switch on, the ESC will give the initialization
tone and flash. Then the arming tone will ring a second
or two later. If the ESC is programmed for the Auto-LiPo
setting, it will beep the number of cells in your LiPo pack
between the initialization tones and the arming tones.
After the arming tone plays, the ESC is ACTIVE and will
respond to throttle application.
If you have problems calibrating your transmitter with
the Losi ESC, please contact the appropriate Horizon
Hobby Service Center. Once you are calibrated and
armed, do one last check before going out and
experiencing the Losi brushless difference. Slowly
advance the throttle and check the rotation direction of
the motor and the color of the LEDs on the ESC. If the
motor is spinning in the right direction and the GREEN
LED is blinking, then you are ready for a test run before
going into the settings of the ESC. If the ESC displays
the green LED with throttle but the wheels spin in the
wrong direction, you’ll need to switch any two of the
motor wires (example: switch from red to red and black
to black to red to black and black to red).
Manual Programming
Follow these steps to change settings on the ESC
without a computer.
Remove your pinion gear before calibration and manual
programming as a safety precaution.
STEP 1: Start with the transmitter ON and the ESC
switched OFF and not connected to the battery.
STEP 2: Plug a battery into the ESC. Hold full throttle on
the transmitter and turn the ESC switch ON. After a few
seconds you will hear four rings signaling full throttle
calibration. Continue holding full throttle. After a few
more seconds, you will hear another four rings. After the
second group of four rings, relax the throttle to neutral.
If you have successfully entered programming mode, the
ESC will beep twice, pause, and repeat the two beeps.
STEP 3: The programming sequence is always presented
in sequential order and always starts with the first
setting (Reverse Lockout) within the first section (Reverse
Type). The first beep(s) signifies which section of the
programming you are in and the second beep(s) signifies
which setting is waiting for a “yes” or “no” answer.
As you cycle through the options, you will need to
answer “yes” by holding full throttle or answer “no”
by holding full brake until the ESC accepts your answer
by beeping rapidly. Once an answer has been accepted,
relax the throttle back to neutral for the next question.
After a “no” answer is accepted, the ESC will present
you with the next option in that section. After a “yes”
answer is accepted, the ESC skips to the first option in
the next section.
Settings & Explanations
The ESC is extremely flexible and may be “tuned” like
any other part of your car or truck. The following section
explains all the settings available to you via manual
programming and what each one does to change the
reactions of the ESC in order to tune it to your specific
preferences.
1. Brake/Reverse Type
Sets whether reverse is enabled and how it can be
accessed.
Setting 1: Reverse Lockout (Default)
This setting allows the use of reverse only after the
ESC senses two seconds of neutral throttle. Use it for
race practice sessions and bashing, but check with
your race director to see if this setting is allowed for
actual racing.
Setting 2: Forward/Brake Only
Use this setting for actual sanctioned racing events.
Reverse cannot be accessed under any circumstances
with this setting.
Setting 3: Forward/Brake/Reverse
Reverse or forward is accessible at any time after
the ESC brakes to zero motor RPM (if the vehicle is
moving).
2. Brake Amount
Sets what percentage of available braking power is
applied with full brake.
Setting 1: 25% Power
Allows only 25% of available braking power at full
brake.
Setting 2: 50% Power (Default)
Allows only 50% of available braking power at full
brake.
Setting 3: 75% Power
Allows 75% of available braking power at full brake.
Setting 4: 100% Power
Allows all available braking power at full brake.
3. Reverse Amount
Sets how much power will be applied in the reverse
direction, if reverse is enabled.
Setting 1: 25% Power
Allows only 25% power in reverse.
Setting 2: 50% Power (Default)
Allows only 50% power in reverse.
Setting 3: 75% Power
Allows only 75% power in reverse.
Setting 4: 100% Power
Allows 100% power in reverse.
4. Punch/Traction Control
This setting controls how fast the throttle position within
the ESC can be changed over time. This smoothes high
power starts and limits punch somewhat. As explained
previously, acceleration is a matter of battery capability,
but you may not want 100% of what the battery can
deliver in every situation.
This setting is crucial to drag racing as it can be used as
a “traction control” to match traction conditions.
The lower the setting, the less throttle change limiting
there is. For pure burnout and wheelie action, use
a very low setting or the disabled setting. For softer
acceleration or for a low-grip surface, raise it up to a
higher setting.
Setting 1: High
Very limited acceleration. Good for 2WD vehicles on
hard dirt, or for general bashing when you want to be
gentle on the transmission.
Setting 2: Medium
Medium acceleration limiting. Good for 2WD vehicles
on soft dirt, and 4WD vehicles on hard dirt.
Setting 3: Low
Light acceleration limiting. Good for 4WD vehicles on
soft dirt.
Setting 4: Lowest
Very light acceleration limiting. Good for most
situations including 4WD vehicles on dirt and asphalt,
and 2WD vehicles on asphalt.
Setting 5: Disabled (Default)
Acceleration is only limited by battery ability. This
setting is good for 4WD sedans on carpet, high
traction drag racing, or bashing where unlimited
wheelie power is desired.
5. Drag Brake
Sets the amount of drag brake applied at neutral throttle
to simulate the braking effect of a neutral brushed
motor while coasting.
Setting 1: Drag Brake OFF (Default)
Vehicle will coast with almost no resistance from the
motor at neutral throttle.
Setting 2: Drag Brake 10%
Low amount of braking effect from the motor at
neutral throttle.
Setting 3: Drag Brake 20%
More braking effect from the motor at neutral throttle.
Setting 4: Drag Brake 30%
Fairly high braking effect from the motor at neutral
throttle.
Setting 5: Drag Brake 40%
High braking effect from the motor at neutral throttle.
6. Dead Band
You may adjust the neutral throttle “width” of the
controller with this setting. Smaller values make the
controller enter forward or brake/reverse with a smaller
movement of your throttle trigger for finer control.
