Gearing:
Follow your motor manufacturer’s recommendations for gearing options.
Gear Mesh:
To correctly set your gear mesh, follow the steps below:
1. Loosen the set screw on the motor’s pinion gear. The set screw can be accessed through the slot on the side of the
motor mount slide, opposite the spur gear. Slide the pinion on the motor shaft until the gear face of the pinion is entirely
aligned with the gear face of the spur gear (see diagram). Tighten the set screw while ensuring it is aligned with the flat
face on the motor shaft.
2. Loosen the two motor mount slide screws until the slide is able to move
freely. Slide the motor as far as it can go towards the spur gear, ensuring
that the teeth of the pinion and the spur gear are interlocking.
Back the motor mount slide off a tiny bit (approximately 0.5 mm), and tighten
the screws that lock the motor mount in place. Proper gear mesh has been
achieved when the teeth are meshing closely, but the gears still have a small
amount of play between them. If you hold one gear, you should be able to rock
the other gear back and forth a small amount. If there is not “free play”, your
gear mesh is too tight and you should back off the motor a little farther.
Differential Fluid:
Team Associated includes a complete bottle of 5,000cst diff oil. You can also provide your own oil and try one of the
optional setups.
Standard differential fluid setup: Front = 5,000cst; Center = 5,000cst; Rear = 5,000cst.
Optional diff setup 1 (high grip track): Front = 5,000cst; Center = 10,000cst; Rear = 5,000cst.
Center Differential:
Use the standard setup for most cases. Some racers will try thicker oil (7,000-10,000cst) when greater acceleration
is needed. This is typically done on very smooth tracks since thicker fluid can reduce handling in bumpy conditions.
Front Differential:
Use the standard setup for most cases. Try 7,000cst to 10,000cst to get less low speed steering and better
acceleration out of turns.
Kickup Bushing:
Generally more kick-up will provide better handling in the bumps and have better straight line acceleration.
Less kick-up will provide more all around steering and have a more aggressive feel.
Caster:
The standard caster block insert setup is for 16 degrees. The standard inboard kick-up is 9 degrees (2-dot up insert
in A-plate). You can reduce the caster using 14 degree inserts (also move both upper cone washers in front of the ball
joint) for smoother steering. Changing to 18 degree inserts (also move both upper cone washers behind the ball joint)
will typically provide more steering on power but reduce handling in bumpy conditions.
Front Upper Pivot Insert:
The standard setup is to use 2-dot up in the tower and 1-dot in the top plate. It is recommended to maintain a 1 dot
gap (1mm per dot) front to rear when using 2-dot up in the A-Plate. Reducing the A-Plate insert to 1-dot allows the use
of same dot number insert in both tower and top plate. Going up to 3-dot up in the tower will give more turn in, but less
steering on power/exit. Going down (1-dot, 2-dot down) will reduce turn in, but give more steering on exit.
Front Camber Link-Outer:
The standard short location will work the best for most tracks. Going to the long front link will give you more steering,
but can make the car less predictable in bumps and exiting turns.
