Adjusting the Slipper
should be done after the diff is properly adjusted. If you have just finished adjusting the differential, loosen
the slipper adjustment nut four full turns (e.g., 360 degrees x 4) to return the adjustment to the setting originally described in the
assembly instructions. To make the final adjustments, place your car on the racing surface and give the car full throttle. The slipper
should slip for one or two feet. If the slipper slips for more than two feet, youll need to tighten the adjustment nut. If the slipper
doesnt slip for at least one foot, back off the adjustment nut 1/8 of a turn and retry. If you cant hear the slipper when you punch
the throttle, hold the front of the car with the rear wheels still on the track and give the car full throttle. The car should push against
your hand with reasonable force and the slipper only slipping slightly. Don't expect the slipper to make up for poor driving or set-
up. You still have to use the throttle and maintain the shocks and chassis. The slipper will help you drive more comfortably and help
accelerate of corners and land jumps.
The Most Sensitive Adjustments,
and the most used by the Team Losi race team, are the number of washers under the front
camber link ball studs and the anti-squat. See these two sections and try to familiarize yourself with the way that these adjust-
ments affect the handling of the
XXX-BK2
.
Ride Height
is an adjustment that affects the way your car jumps, turns, and goes through bumps. To check the ride height, drop
one end (front or rear) of the car from about a 5-6 inch height onto a flat surface. Once the car settles in to a position, check the
height of that end of the car in relationship to the surface. To raise the ride height, lower the shock adjuster nuts on the shocks
evenly on the end (front or rear) of the car you are working on. To lower the ride height, raise the shock adjuster nuts. Both left
and right nuts should be adjusted evenly.
You should start with the rear ride height where the car comes to a rest at a height where the dogbones are slightly below level
with the surface. The front ride height should be set so that the bottom of the chassis is level with the surface. Occasionally, you
may want to raise the front ride height to get a little quicker steering reaction, but be careful as this can also make the car flip over
more easily.Every driver likes a little different feel so you should try small ride height adjustments to obtain the feel you like. We
have found that ride height is really a minor adjustment. This should be one of the last adjustments after everything else has been
dialed in. Do not use ride height adjustment as a substitute for a spring rate. If your car needs a softer or firmer spring, change the
spring. Do not think that simply moving the shock nuts will change the stiffness of the spring; it will not!
Rear Hub Camber Location
is best set according the settings described in this manual. You should start with the inner hole in
the top of the hub (hole "A"). The outer hole will tend to make the car feel a bit stiffer. This results in the car accelerating straighter
and also makes it a bit eassier to line up for jumps. Moving to the inner hole will typically make the car go through bumps better.
The inner hole may also give the feeling of more steering. This steering generally comes from the rear end though. What this
means is that the rear end of the car may swing a bit more at times even sliding more.
Rear Camber Link Length
can be another useful adjustment. It is virtually impossible to make a blanket statement for exactly
how the length of the camber link will affect the handling under all conditions. The following is our experience with how the length
of the camber link will typically affect the handling of the
XXX-BK2
. A longer rear camber link will usually result in more rear
traction. With a longer link, the car can start to drive more square, or point-to-point. This can make it difficult to carve corners at
high speed. A shorter rear camber link will generally result in more steering from the rear of the car due to increased chassis roll.
This can make it easier to change directions quicker, but can cause the rear of the car to roll around if the link is too short. A
shorter rear link will usually go through bumps a bit better than a long link as well.
Front Carrier Camber Location
is another adjustment that is almost always run in the standard (outer) location. This location
keeps the car flatter with less roll. The outer location also helps the car stay tighter in turns with a more precise steering feel.
Moving the link to the inner hole will make the steering react slightly slower. The advantage to the inner hole is that it can increase
on-power steering and help the car get through bumps better.
Washers Under the Front Camber Link Ball Stud
can be added or removed. This is one of the most important adjustments
on the
XXX-BK2
car. You should get a feel for how the number of washers affects the handling. Adding washers will make the car
more stable and keep the front end flatter. Removing washers will make the steering more aggressive. This can be good in some
conditions, but can also make the car difficult to drive in others. The best all-around adjustment is with one washer as per the
assembly instructions.
Front Camber Link Length
is another adjustment that is difficult to make a generic statement for as it can have slightly
different results on various conditions. The following is a summary of how this adjustment will usually impact the handling of the
