MRX50-Bl Installation
When installing the MRX50-BL into a Losi 1/24 Micro,
use the included Chassis Top Cover to replace the Top
Cover provided with the RTR.
1. Remove the Chassis Top Cover as shown in the
specific vehicle instruction manual.
2. Unplug the wire connectors from the servo, motor
and battery.
3. Use a small screwdriver to push back gently on
the rear locking tab to remove the ESC/Receiver
switch from the chassis.
4. Remove all 4 screws that secure the original ESC/
Receiver unit to the mounting surfaces.
5. Remove the original ESC/Receiver unit.
6. Start installation of the MRX50-BL by pressing the
switch into the chassis between the front and rear
switch mounting tabs. Be sure to have the two
switch posts with wires attached toward the “ON”
marking on the chassis to ensure the On/Off function
of the ESC/Receiver is correct to the marking on
the chassis.
7. For Brushed Motor operation, connect the Brushed
Motor’s Micro 2-Wire connector to the 2-Wire side
of the adapter; then connect the 3-Wire side of the
adapter to the MRX50-BL Micro 3-Wire connector;
the connectors are designed to only connect one way.
For Brushless Motor operation, connect the Brushless
Motor’s Micro 3-Wire connector to the Micro 3-Wire
connector of the MRX50-BL; the connectors are
designed to only connect one way.
8. Pull the 2-Wire battery connector toward the rear of
the chassis, and guide it though the open slot in the
chassis into the battery compartment.
9. For the Micro 1/24 vehicles, guide the gray
antenna wire through the small hole in the rear
of the included Brushless Micro 1/24 Top Cover.
Also, guide the servo plug and wire through
the opening in the Micro 1/24 Top Cover directly
behind the servo and pull through. Then secure
the cover to the chassis as shown in the specific
vehicle instruction manual.
For all other Micros vehicles, guide the gray
antenna wire through the small hole in the
rear of the ESC/Receiver unit cover, and
reinstall as instructed in the specific vehicle
instruction manual.
10. Plug the servo wire into the appropriate location.
Connect the 5-wire servo plug to the 5-wire
input or the 3-wire servo plug to the 3-wire
input noting proper orientation (the signal
wire is towards the front of the chassis).
Connecting the Battery
Use a Losi Micro 4-cell (4.8-volt) NiMH battery pack
or a 2S-3S (7.4-11.1-volt) LiPo pack.
NOTICE:
Do not use 3S (11.1-volt) LiPo batteries
with brushed motors.
1. Move the on/off switch to the “off” position.
2. Connect a fully charged battery pack to the
battery connector of the ESC/Receiver.
adjusting the Transmitter
Adjust the transmitter prior to powering on the
MRX50-BL ESC.
1. Set the “throttle reversing” setting to the
NORMAL position.
2. Set “throttle trim” to the CENTER or ZERO
position.
3. Set throttle “end point adjustment (EPA)”
to 100% in each direction.
CauTION:
Always power on the
transmitter before the receiver. Always
power off the receiver before the transmitter.
Binding Receiver to Transmitter
Binding is the process of programming the receiver
to recognize the GUID (Globally Unique Identifier)
code of a single specific transmitter and to store
failsafe values. When a receiver is bound to a
transmitter/model memory, the receiver will only
respond to that specific transmitter/model memory.
Binding
1. Press and hold the bind button while powering
on the receiver.
2. The green LED will flash continuously, indicating
that the receiver is in bind mode.
3. Release the bind button.
4. Move the steering wheel and throttle
to the desired failsafe positions.
5. Enter the transmitter into bind mode.
Refer to your transmitter instruction
manual for more information.
6. The green LED on the receiver will be solid when
the receiver and transmitter are bound.

failsafe
Failsafe positions are stored during binding. In
the unlikely event that the radio link is lost during
use, the receiver will move the servos to their
preprogrammed failsafe positions (normally full
brakes and straight steering). The only time it is
necessary to re-bind your receiver and transmitter
is if you desire different failsafe positions. Always
re-bind your transmitter and receiver after any
changes to throttle channel reversing.
NOTICE:
Failsafe protects against signal loss from
the transmitter.
failsafes will not activate in
the event that power to the receiver is lost.
