frequency is like a TV channel.The transmitter you hold in your hand is like the TV station and the model
with the matching crystal is like your TV tuned exclusively to the channel of the station.The Micro radio
is equipped with changeable crystals that allow you to change the frequency/channel you operate on.
This is especially useful when you want to run a group of Losi Micro’s at the same time.When changing
crystals/channels, you must always replace the crystals as a set with one going in both the transmitter
and the receiver in the truck. Each of the 6 different channels are numbered and color-coded. Each set
includesauniquecrystalforthereceivermarked(Rx)andonefromthetransmittermarked(Tx).The

Slipper Adjustments
The Losi Micro Raminator is equipped with a slipper device
that offers both traction control and protection for the
transmission.The slipper is primarily used to help absorb
suddenimpactsonthedrivetrainduetolandingbigjumpsor

with your thumb.To track test, turn the Losi Micro Raminator
on and place it on the ground. As you push it backwards,
allowing it to roll freely, punch the throttle.The slipper should
slip no more than an inch or two as it accelerates. Make sure
you replace the gear cover before running.
Steering Rate
Your transmitter is equipped with a steering rate control to the left of the steering wheel.This advanced
feature,usuallyfoundonlyoncompetition-typeradios,allowsyoutoadjusttheamountthefronttires

Cleaning
Performance can be hindered if dirt gets in any of the moving suspension parts. Use compressed air,
a soft paintbrush, or toothbrush to remove dust or dirt. Avoid using solvents or chemicals, as they can
actually wash dirt into the bearings or moving parts as well as cause damage to the electronics.

Rebuilding the Differential
The gears in the differential will wear over time.The same is true for the outdrives, driveshafts and
rear axles.We suggest using a small rag or paper towel to lay out the parts you remove to make it
easier to reassemble.

end of the slipper shaft and all of the slipper parts on the outside of the spur gear as well as the old gear.
Place the new spur gear into position and replace the slipper parts. After you have changed the spur gear,
youwillhavetoadjusttheslipperasdescribedinthe“SlipperAdjustment”sectiononpage3.
Changing the Pinion Gear/Gear Ratio
Before you change the pinion, ask yourself why you are doing it. In general, if you change to a larger
pinion the top speed will improve, but you will see less acceleration and run time.This would only be
advisable for really long track layouts with few tight turns. Changing to a smaller pinion will give you
quicker acceleration and possibly a bit longer run time but a little less top speed.This would be good for
short layouts or when running faster motors.The Micro Raminator comes with a 10T pinion that offers
the best balance of both.To change the pinion, remove the gear cover, loosen the motor screws, and slide
themotorback.Useasmallflatheadscrewdriverbetweenthemotorplateandpiniongeartopushthe
gear off. Place the new pinion on the end of the motor shaft and press the new pinion gear into the same
position as the one removed.

rocking the spur back and forth.There shoud be a slight bit of movement before the
motor is forced to turn over. If not, pull the top of the motor back slightly and recheck.
If there is too much slop between the gears, push the top of the motor forward.When
set properly, the wheels can be spun forward freely with very little noise. Make sure to
tighten both motor screws and replace the gear cover before running.
