BREAK-IN PROCEDURE
When starting, hold the throttle slightly open. If the engine is difficult to turn over, loosen glow plug 1/2-turn before starting engine (this allows
some compression to escape while allowing the engine to start). Once engine starts tighten the glow plug.
IMPORTANT! FLOODED ENGINE:
IMPORTANT! FLOODED ENGINE: If the Super Start still is having problems turning the engine over, it is flooded (too much fuel inside the engine).
1. Remove glow plug and turn vehicle upside down, pointing away from you.
2. Run Super Start for 5-6 seconds (clearing engine of fuel).
3. Replace glow plug.
4. Repeat starting engine steps.
Initial engine break in will be accomplished with the first 5 tanks of fuel. (Full break-in may take up to 15 tanks.)
Initial engine break in will be accomplished with the first 5 tanks of fuel. (Full break-in may take up to 15 tanks.)
1. During break-in, run with the body off to keep the engine cool.
2. Keep air filter on at all times.
3. Run on smooth, hard surface.
4. Make sure you have extra glow plugs. Break-in puts stress on the glow plug
and it may need to be replaced.
TANK 1
TANK 1
Run very rich allowing fuel to carry as much oil as possible to lubricate internal engine parts.
1. High Speed Needle Valve: Check this setting before running. Close the high speed
needle by rotating it clockwise until you just feel resistance, then open to 3 full turns out
(counterclockwise).
2. Run at medium speeds, slowly accelerating and decelerating.
NOTE:
NOTE: It is normal for the
two speed NOT to shift during this tank.
3. If engine does not stay running consistently, increase idle speed by turning the idle stop screw clockwise.
4. DO NOT allow the tank to run out of fuel during break-in.
5. Stop engine by placing the engine tool into the exhaust outlet. Allow it to cool approximately 10 – 15 minutes.
TANKS 2-4
TANKS 2-4
1. For each additional tank, lean high speed needle 1/12 turn from the previous tank’s setting.
2. Stop engine, allowing it to cool approximately 10 – 15 minutes, between each tank.
TANK 5
TANK 5
1. Lean high speed needle an additional 1/12 turn from Tank 4 setting.
2. The engine should now be very close to final tune and be broken in and ready to be performance tuned.
TUNING TIPS (Adjust only after the engine is fully broken in.)
TUNING TIPS (Adjust only after the engine is fully broken in.)
IMPORTANT!
IMPORTANT! Always run the engine for 1-2 minutes to warm up temperature before tuning! Only use “small” adjustments (1/12 turn at a time) and test
the results.
High Speed Needle
High Speed Needle
:
: Controls the fuel/air mixture at high throttle settings. A properly tuned engine will accelerate smoothly and exhaust a
small amount of smoke. The goal is to tune the engine to make good power without overheating. Engine temperature should stay around
250° F (132° C) using a temperature gauge (Duratrax Flashpoint™, DTXP3100).
Note:
Note:
This temperature is a “guideline” only. Your engine may run slightly warmer or cooler
depending on conditions; fuel, track, and how you drive.
On hot days, additional cooling may be needed. Cut a 60mm hole in the rear window to
allow more airflow through the body.
Low Speed Needle
Low Speed Needle
:
: Controls fuel mixture at low throttle settings (idle). To check this
setting, keep the throttle at idle and pinch the fuel line close to the carburetor. A
correct setting will increase the engine speed after 2-3 seconds and then lose speed.
• If it slows too quickly, the mixture is too lean. Open the low speed needle (counterclockwise).
• If it takes longer than 4 seconds to slow down, the mixture is too rich. Close the low speed needle (clockwise).
Idle Stop Screw:
Idle Stop Screw: Adjust this screw to set the idle speed so the wheels do not rotate when you lift the vehicle off of the ground. When looking
into the carburetor, the barrel should be about 1mm from fully closed.
CARE AND MAINTENANCE
CARE AND MAINTENANCE
1. Keep engine clean and free of dirt.
2. Do not over lean engine.
3. Run all of the fuel out of the engine before storing.
4. Use after run oil and work it into the engine by turning the flywheel before storing .
5. Do not use a fuel with a nitromethane content over 30%.

TUNING GUIDE
As a starting point, make sure your car has equal lengths on shocks, camber links and steering rods on both sides (left
and right). Front and rear do not need to be equal.
Upper Arm Spacer
Less Caster = Arm forward More Caster = Arm back
Upper Arm Spacer
CASTER
Angle of the front knuckles in relation to the ground when
viewed from the side.
• Increased off power steering
when entering a corner.
• Straight line stability.
• Vehicle more responsive.
• Decreases on power steering
when entering a corner.
• Turns feel smoother.
More Ackerman
Less Ackerman
ACKERMAN
The difference in turning angle between the inside wheel
and outside wheel in a turn.
Less Ackerman
Less Ackerman = Inside wheel turns more equal to the outside wheel.
Move steering rod forward on the knuckle or back on the bellcranks.
Less aggressive steering, smoother cornering.
More Ackerman
More Ackerman = Inside wheel
turns increasing more than the
outside wheel. Move steering
rod back on the knuckle or
forward on bellcranks.
More aggressive steering,
vehicle turns more abruptly.
0°
-2°
CAMBER
Angle of the tire and wheel in relation to the ground when
viewed from the front.
Negative Camber
Negative Camber = Tire and wheel lean inward (Typically 0° to -2°)
• Improved traction while corning.
• Adds overall stability.
Positive Camber
Positive Camber = Tire and wheel lean outward (This is NOT recommended)
Highest roll center Lowest roll center
ROLL CENTER
Point at which the vehicle rolls laterally when cornering.
Raising Roll Center:
Raising Roll Center: Raise rear camber rod mounting location on the hub.
Increases rear on power traction and decreases rear traction during braking.
Lowering Roll Center:
Lowering Roll Center: Lower rear camber rod mounting location on the hub.
Decreases rear traction on power, reduces corner entry steering and
increases corner exit steering.

FRONT TOE-IN AND TOE-OUT
Direction the wheels point in relationship with each other,
when viewed from above.
Toe-Out
Toe-Out
:
: Fronts of the wheels point away from each other.
• Decreased stability when accelerating and increased steering when
entering a corner.
Toe-In:
Toe-In: Fronts of the wheels
point toward each other.
(Typically 0 to -2°)
• Increased stability when
accelerating. Decreased
steering when entering a
corner.

2-SPEED SHIFT POINT
Proper shift point helps keeps the engine within its optimum
RPM range.
Shifts too soon
Shifts too soon (Vehicle will lose acceleration)
:
: Turn the screw in, making
the vehicle shift later and engine rev higher before shifting.
Shifts too late
Shifts too late (Vehicle will not hit top speed): Turn the screw out, making
the vehicle shift sooner and engine rev less before shifting.
THE ENGINE MUST BE
COMPLETELY BROKEN IN
AND UP TO OPERATING
TEMPERATURE BEFORE
MAKING SHIFT POINT
CHANGES.
IF YOU NEED TO MAKE A
CHANGE, STOP THE ENGINE!

CHASSIS MAINTENANCE TIPS
Check before every run:
1. All hardware to be sure everything is tight.
2. Transmitter batteries.
3. Moving parts are free from binding.
4. Parts are not broken or damaged.
5. Wires are properly connected.
6. Remove dirt or debris from chassis and moving parts.
7. Bearings should roll smoothly.
8. Shocks should operate smoothly. Check for leakage and refill as needed.
9. Gear mesh between the spur and pinion gears.
SHOCK ADJUSTMENTS
Top Shock Outer Positions:
sDecreases steering
sQuicker suspension reaction
FRONT
Top Shock Inner Positions:
sMore aggressive steering
sSmoother over bumps

Screws adjusted so arms drop less.
Screws adjusted so arms drop more (more droop).
DROOP
Distance the chassis can lift from ride height before the wheels come off the ground.
More Front Droop:
More Front Droop: Increases chassis up travel when on throttle and decreases high speed steering, making vehicle turn smoother. Good for low traction and bumpy surfaces.
Less Front Droop:
Less Front Droop: Decreases chassis up travel when off throttle and under braking, making steering more aggressive. Good for high speed smooth surfaces.
More Rear Droop:
More Rear Droop: Increases chassis up travel when off throttle and under braking. Increases steering in low speed corners and under braking.
Less Rear Droop:
Less Rear Droop: Decreases steering in low speed corners, making the vehicle turn smoother.
More spacers on the front shock. More spacers on the rear shock.Same number of spacers front and rear.
RIDE HEIGHT
Distance the chassis sits from the ground and how much weight is transferred when the vehicle changes speed and direction.
Lower Rear:
Lower Rear: More rear traction but reduces steering.
Lower Front:
Lower Front: Increases steering but can cause
rear end to break loose.
