Re-Binding the Transmitter to the Receiver
The Losi™DSM®radiosystemincludedintheMini-LateModeloperateson2.4GHz,andprovides79dierentchannels,which
are automatically selected when the transmitter and vehicle are turned on. The communication between the transmitter and
receiver starts in the few seconds after the transmitter and vehicle are both turned on. This is called the “binding process.”The
LosiDSMradiosystemwillnotinterferewithprevioustechnologyradiosystemsthatoperateon27MHzor75MHzfrequencies
and you will not receive any interference from them.
Although set at the factory, below are the steps required to re-bind your transmitter to the receiver should the need arise.
During the bind process there is a unique ID from the transmitter communicated to the receiver to ensure trouble free radio
operation.
Steps to Re-Bind the Receiver to the Transmitter
1. Ensurethatthetransmitterandvehiclearebothturnedo.
2. UsingthesuppliedBindplug(whichlookslikeastandardreceiver
plugwithawireloopinstalled)insertorplugintothereceiverslot
labeled “BIND”. Looking down on the receiver this slot would be
below the LED and is the furthest from the LED, or nearest to the
corner of the receiver.
Note: You do not need to remove any of the other plugs
to re-bind.
3. With the Bind plug installed, turn on the vehicle. Notice a blinking
OrangeLEDwithinthereceiver
4. Now you are ready to turn on the transmitter. You should notice
onthebackofthetransmitterasimilarblinkingOrangeLED
under the translucent cover.
5. BoththereceiverandtransmitterblinkingOrangeLEDwill
stop blinking and become solid indicating they have“bound”
themselves together.
6. Pleaseturnoboththevehicleandtransmittertoremovethe
Bind plug from the receiver. Failing to remove the Bind plug will
cause the transmitter to attempt to rebind every time you turn on the vehicle and transmitter.
7. Turn on both the vehicle and transmitter to ensure operation. If the transmitter does not control the vehicle, please
repeatsteps1to6.ShouldthisnotcorrecttheproblempleasecallHorizonService/Repairforfurtherassistance.
8. The Bind process is complete. Your vehicle’s radio system should be ready for use.

Chassis Tuning
The Mini-Late Model has several adjustments available to you for tuning the performance for your needs. Although
there are multiple shock positions and camber link locations provided, we have built the model with the best overall
settings. The following are simple adjustments and easily maintained settings to assure proper operation and performance.
It is advised when making any adjustment that you do so in small increments and always check for other parts of the chassis
thatareaected.
Slipper Adjustments
TheMini-LateModelisequippedwithaslipperdeviceoering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 when
using more powerful aftermarket motors and/or battery packs. Additionally,
it can be used to smooth out the flow of power to the rear wheels and limit
wheel spin when running on extremely slick surfaces. Adjustment is made by
turningthe3mmadjustmentnutclockwise(totheright)toreducetheslip,
orcounterclockwise(totheleft)toincreasetheslip.When
adjusted properly, you should be able to hold the rear tires
firmly and barely be able to push the spur gear forward with
your thumb. To track test, turn the Mini-Late Model 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. With the included motor
and battery pack it should slip just a little. 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 move when you turn the steering wheel. This
is really helpful when you are on slick, as well as high-traction surfaces. If your Mini-Late Model turns too sharply and/or spins
outeasily,tryturningthesteeringratedownbyrotatingtheknobcounterclockwise(totheleft).Forsharperoradditional
steering,tryturningtheknobclockwise(totheright).

Camber
Camber is the angle of the tires to the racing surface when viewed from the
front or rear of the vehicle. You want to keep both the front and rear tires
straight up and down or leaning in at the top very slightly. If you are running
on carpet or similar high-traction surfaces, you may find leaning the tires in
a bit more helps. This adjustment is made with the threaded links extending
from the front or rear bulkhead to the spindle carrier or rear hub. Making
the camber rods shorter increases the camber and lean-in of the tire, while
making the camber rods longer decreases the camber.
Toe-In/Toe-Out
This is the relationship of the left and right side
tires to one another. Ideally you want the front of
the tires to be pointed inward to each other just
slightly when viewed from above. This makes the
model track straight and stable. This is controlled
with the threaded steering rods on either side.
As you make them longer you will increase the
toe-in and vice versa. By shortening the links, you
will gain toe-out, which will give the model more
o-powersteeringandmakeitwanderonthe

Ride Height
Thisistheheightthechassissitsandrunsat.SpringspacersincludedwiththeMini-LateModel,wheninstalledbetweenthe
shock top and spring, will increase the pre-load on the spring and raise the chassis. You may want to try this when running on
extremely rough surfaces.
Battery Location
The Mini-Late Model has multiple battery locations. The stock configuration is with the battery in the center of the vehicle in
the back location. You are also able to run the battery in the forward location by putting the battery foam in the rear of the
batterytrayandmovingthebatteryforward.Runningthebatteryintheforwardlocationwillyieldlesso-powersteering
but more on-power steering. The battery also can be used on the left side of the chassis for improved corner speed. Please be

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.

8. Remove the center mounted idler gear from the gearbox. Remove
the shaft and push out the ball bearings from either side. Install these
bearings in the new gear.
Reassembly
Replace the idler gear and shaft into the center of the same right side of
the gearbox. Replace any shims removed from the right bevel gear and
slideitthroughthelowerbearing.Replaceanyshimsthatcameoofthe
left side bevel gear and allow them to slide through the lower bearing as
you put the left gear box half back into position. Replace the screws and
reinstall the rebuilt gearbox using the steps in reverse order that were used
to remove it.
Changing the Spur Gear
Removethegearcoverbyremovingthethreesmallscrews.Ifyouarereplacingthespurgearwithoneofadierentsize
(numberofteeth),youmustrstloosen(donotremove)thetwoscrewsthatsecurethemotorandslideitbackslightly.
Remove the 3mm nut at the 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. If you have changed the size of the spur,
seeSettingtheGearMeshbelow.Afteryouhavechangedthespurgear,youwillhavetoadjusttheslipperasdescribed
elsewhere.
Changing the Pinion Gear/Gear Ratio
Before you change the pinion gear 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hottermotors.ThepinionontheMini-LateModeloersthe
best balance of both. To change the pinion, remove the gear cover, loosen the motor screws, and slide the motor back. Use a
pairofsmallneedle-nosepliersbetweenthemotorplateandbackofthepiniontopushthepiniono.Placethenewpinion
on the end of the motor shaft and, using the flat of the pliers or a similar flat tool, push it on to the same position as the one
removed.SeeSettingtheGearMeshbelow.YourMini-LateModelcomesequippedwitha16-toothpinion,whilethispinion
gear is optimal for most tracks you may find that the included 12-tooth and 14-tooth pinion gears can be advantageous on
shorter tracks.
Warning: When running aftermarket motors, check with the motor manufacturer for correct gearing. Never over-gear
the motor as it can cause overheating, damaging it and the speed control.
Setting the Gear Mesh
Themotorscrewsshouldbeslightlyloose.Slidethemotorforwardallowingthepiniongeartomesh
withthespurgear.Snug(nottight)thebottommotorscrewandtryrockingthespurbackandforth.
There is 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.
