22S PRO NO PREP DRAG ROLLER: 1/10 SCALE 2WD • INSTRUCTION MANUAL
INSTALL THE BATTERY
The Losi 22S drag car wheelie bar is designed to provide optimal adjustment. There are two
adjustment options, allowing for height fine tuning, as well as easy adjustment.
ROUGH TUNING
1. Move the lower turnbuckle attachment point forward or backward to set the wheelie bar to
the required height.
2. Move the attachment point back to raise the wheelie bar and to provide more support to
the wheelie bar rear.
FINE TUNING
Adjust the turnbuckle to fine tune the wheelie bar height, precisely controlling the height of
the wheelie bar wheels from the ground.
TIP:
Wheelie bar wheels ½ inch from the ground provides appropriate clearance and ad-
equate rear wheel traction during full acceleration.
CAMBER ADJUSTMENT
Camber is the angle of the wheel top from straight up and down.
Leaning in
is Negative Camber;
leaning out
is Positive Camber.
As the vehicle turns, the chassis rolls. As the vehicle rolls, the tires lean toward the turn, caus-
ing less tire surface to come in contact with the ground (at 0° camber). To compensate for
this, a few degrees of negative camber are added at the factory.
Front Camber Effects:
Adding approximately -1 to -2 negative camber provides optimal
contact to the ground, allowing for adequate front end traction. Adding additional camber
decreases steering traction. If the steering feels loose, remove a degree of camber.
Rear Camber Effects:
Camber affects two things on rear suspension. In a straight line,
maximum acceleration is achieved using 0° of camber. Adding camber reduces forward trac-
tion, but increases steering stability. If the vehicle is loose, add rear camber to keep the vehicle
going straight.
1. To adjust the front and rear camber, select one of several hole positions on both hubs as
well as the camber blocks. The rear camber block is integrated into the shock tower.
2. Adjust the turnbuckle for fine tuning.
TOE ADJUSTMENT
FRONT
Adding Toe-In will increase on-power steering and provide a more directing steering feel.
Adding Toe-Out will decrease on-power steering and may provide the feel of more rear traction.
REAR
More Toe-In: Increased forward traction. Increase toe-in on lower traction surfaces.
Less Toe-In: Decreased forward traction. Decrease toe-in on higher traction surfaces.To adjust
the rear toe:
The stock rear toe on the 22S Roller is 3 Degrees. Adjust the rear toe using the Rear Pivot
Block Set (LOS234048) which includes 1.5, 3, and 4.5-degree pivot blocks.
1. Ensure the ESC is powered OFF.
2. Remove one side of the elastomer strap from the battery posts.
3. Slide a fully charged battery in through the vehicle front until the battery drops into place.
4. Resecure the elastomer straps to the battery posts.
5. Connect the battery to the ESC noting the correct polarity.
6. Power ON the transmitter, then the vehicle.
