   Be sure to keep the tower cover centered on the tower.

3. The cover should snap into place with the tap locking on the back side of the tower.
   NOTE: The tower cover was designed to key into place with the supplied LP SHCS. Use of another screw type is not recommended.

#92417 – Front Wing Mount is used as a tuning option to increase front end stabillity by adding a front wing (included).

Hinge Pin will be tight in the rear hub, but should rotate freely in the rear arms. :: Bag 8 – Step 1 Racers Tip:
Use black grease (#6588) on the threads of the turnbuckles for easier ball cup installation!
Orient the notch to the left throughout the car. It indicates which end has the left hand threads! Measurements given are approximation. Camber should be set with a gauge at ride height. :: Bag 8 – Step 2

Orient the notch to the left throughout the car. It indicates which end has the left hand threads! :: Bag 8 – Step 3 Orient the notch to the left throughout the car. It indicates which end has the left hand threads! Measurements given are approximation. Camber should be set with a gauge at ride height. :: Bag 9 – Step 1 Mount the shock 0pistons with the number facing up!
Racers Tip:
Use a marker over the numbers on the pistons to make them easily visible! :: Bag 9 – Step 2 Lightly rub shock oil on the O-ring before installation!
Racers Tip:
Coating the O-rings with green slime (#1105) helps seal & reduce O-ring swell!
Green slime not included in kit! :: Bag 9 – Step 3 Lightly rub shock fluid or green slime on threads
There are 3 lengths of shock eyelet in the kit.
Pay attention to length when building as these aff ect your droop and uptravel.
:: Bag 9 – Step 4 Shock Bleeding Steps:

1. Before assembly, get each bleed screw and thread it 1-2 turns into the shock cap, then remove the screw. This will make it easier when you are bleeding your shocks.
2. Pull shock shaft down.
3. Fill shock body 3/4 full with silicone shock fl uid.
4. Slowly move the shock shaft up and down to remove air from under the piston.
5. Wait for bubbles to come to surface.
6. Fill shock body to top with silicone shock fl uid.
7. Place a drop of oil in the cap and on cap threads.
8. Install cap (without bleed screw) and tighten completely.
9. Slowly compress shaft all the way to bleed excess silicone shock fl uid out the hole in the cap (use rag around shock to catch excess fl uid).
10. Install M2x4mm button head screw until snug while shaft is fully compressed.

:: Bag 9 – Step 5 :: Bag 9 -Step 6 Screw collars to top.
Use to adjust ride height. :: Bag 9 – Step 7

There are two options for trimming the kit body on the left rear side.
Dotted line is preff ered if you run a motor fan. :: Bag 10 – Step 5 Install button and washer with wing mount :: Bag 10 – Step 6 Carefully apply CA glue (tire adhesive) to the tire bead on the side. Do one side at a time, allowing it to dry before gluing the other side!
CA glue not included!

Tuning Tips – Painting, Beginners

Painting:
Your Kit requires a clear polycarbonate body. You will need to prep the body before you can paint it.
Wash the INSIDE thoroughly with warm water and liquid detergent (do not use any detergents with scents or added hand lotion ingredients!).
Dry the body using a clean, soft, lint-free cloth. Use the supplied window masks to cover the windows from the INSIDE of the body (RC bodies get painted on the inside). Using high quality masking tape, apply tape to the inside of the body to create a design. Spray (use either rattle can or airbrush) the paint on the inside of the body (preferably dark colors first, lighter colors last). NOTE: ONLY use paint that is recommended for (polycarbonate) plastics. If you do not, you can destroy the body! After the paint has completely dried (usually after 24 hours), cut the body along the trim lines. Make sure to drill or use a body reamer to make the holes for the antenna if needed! Use hook and loop tape to secure the body to the side rails of the vehicle.

Tips for Beginners:
Before making any changes to the standard setup, make sure you can get around the track without crashing. Changes to your vehicle will not be benefi cial if you can’t stay on the track. Your goal is consistent laps. Once you can get around the track consistently, start tuning your vehicle. Make only ONE adjustment at a time, testing it before making another change. If the result of your adjustment is a faster lap, mark the change on the included setup sheet (make adddtional copies of the sheet before writing on it). If your adjustment results in a slower lap, revert back to the previous setup and try another change. When you are satisfi ed with your vehicle, fi ll in the setup sheet thoroughly and file it away. Use this as a guide for future track days or conditions. Periodically check all moving suspension parts. Suspension components must be kept clean and move freely without binding to prevent poor and/or inconsistent handling.
Rear Arm Mount Pill Insert Setup:
The aluminum rear arm mounts utilize eccentric pill inserts to make fi ne adjustments to anti-squat, toe, pin heights, and pin width. Adjustments can be made using the supplied inserts (#92014)
Standard Position
Use this position as a reference when changing pill locations.
Toe: 3°
Anti-squat: 2°
Roll Center: +0
Pivot Width: +0 **** For additional setup tips, please visit our website by using the link or QR code below.

Motor Gearing:
Proper motor gearing will result in maximum performance and run time while reducing the chance of overheating and premature motor failure. The gear ratio chart lists recommended starting gear ratios for the most widely used motor types. Gear ratios will vary depending upon motor brand, wind, and electronic speed control. Consult your motor and electronic speed control manufacturers for more information. Team Associated is not responsible for motor damage due to improper gearing.

B7 Gear Ratio Chart (Internal Gear Ratio 2.60:1)

*75T spur gear (#92294) not included Set The Gear Mesh:
You should be able to rock the spur gear back and forth in the teeth of the pinion gear without making the pinion gear move. If the spur gear mesh is tight, then loosen the #41096 screws (p.19) and move the motor away, then try again.
A gear mesh that is too tight or too loose will reduce power and damage the gear teeth.
Diff Height Adjustment:
The diff height adjustment (p.12) is a good way to tune the car for grip level. On high grip with low ride heights, a higher diff height will be a good option. On lower grip with higher ride heights, a lower diff height will be better.
Slipper Clutch:
The assembly instructions give you a base setting for your clutch. Turn the nut on the shaft so that the end of the top shaft is even with the outside of the nut. At the track, tighten or loosen the nut in 1/8 turn increments until you hear a faint slipping sound for 1-2 feet on takeoffs.
Another popular way to set the clutch is to hold both rear tires fi rmly in place and apply short bursts of throttle. If the clutch is properly set, the front tires should lift slightly up off the surface.
Caster:
Caster describes the angle of the caster block as it leans toward the rear of the vehicle. Positive caster means the kingpin leans rearward at the top. The kit includes three inserts to adjust caster angle at the caster block, 0°, 2.5°, and +5°. The total caster angle is the sum of the kick-up angle and the caster block angle. Standard total caster angle for the B6 is 30°, with 25° kick-up and +5° caster block angle.
For less entry steering and more exit steering, try 0° caster block angle.
Front Camber:
Camber describes the angle at which the tire and wheel rides when looked at from the front. Negative camber means that the tire leans inward at the top. A good starting camber setting is -1°. Positive camber, where the top of the tire is leaning out, is not recommended. A camber gauge can be used to more accurately set camber. ** Testing camber with camber gauge
Rear Camber:**
Camber describes the angle at which the tire and wheel rides when looked at from the back. Negative camber means that the tire leans inward at the top. A good starting camber setting is -1°. Adding a small amount of positive camber, where the top of the tire is leaning out, will tend to improve straight-line acceleration on loose tracks. A camber gauge can be used to more accurately set camber.Front Suspension:
