FINAL ADJUSTMENTS
MAKE THESE ADJUSTMENTS BEFORE RACING
MODEL CAR FUEL
The proper fuel is very important for long
engine life. Improper fuel can cause hard
starting , poor performance, and excessive
wear on the engine. The fuels we recom-
mend for R/C car use are: O’Donnell Rac-
ing fuel, Duratrax Red Alert fuel, Blue Thun-
der Race Formula, FSR fuel, Trinity, Byron’s
Originals, and Traxxas Top Fuel. There are
many other racing fuels, however, they must
meet two requirements.
1) The fuel must contain at least 18%
of both castor and synthetic oils.
2) You should try to keep the nitro
(nitromethane) between 10% to 20%. The
best fuels also contain rust and corrosion
inhibitors, anti wear agents, anti foaming
agents and lubrication additives.
3)
IMPORTANT: DO NOT
use any type
of airplane fuels. Airplane fuels may not have
the necessary oil types and ratios needed
for R/C cars.
GETTING THE RADIO READY
Read your radio instructions that come
in the box with your radio. You should un-
derstand the operation of your transmitter.
Place eight of your AA cells in the transmit-
ter, and put four more in the receiver pack,
at the rear end of the truck.
It is important that all of the AA radio
batteries are strong or fully charged. Al-
ways check the path and the condition of
the battery pack wires as well as the switch
wires. A melted wire can cause a short –
circuit and lead to a loss of control. Large
metal objects such as chain link fences,
light poles, cars, vans, trailers or even fluo-
rescent lights can occasionally cause lo-
cal interference by momentarily blocking or
reflecting a signal.
TESTING THE TRANSMITTER
Important: Always turn your transmitter
on first and off last. Remember this rule.
If
you start your truck before turning on
your transmitter then you will lose con-
trol of the truck and damage your en-
gine quickly.
Test the following radio func-
tions without the engine running.
These following steps will help you under-
stand the operation of your transmitter.
1. Turn on the transmitter . You should see
an indicator light showing that the radio is
on.
2. Turn the car receiver battery pack switch
on. Both the steering servo and the throttle
servo should move to their respective neu-
tral settings.
3. Turn the steering wheel on the trans-
mitter left and right. The front wheels should
turn left and right (when viewed from behind),
then go to a perfectly straight-ahead posi-
tion when the wheel is released. If they’re a
little off, you can set them with the steering
trim control on your transmitter. If your ser-
vos are slow, you might want check your
batteries before you run.
4. Pull on the throttle trigger, which should
open the throttle on the engine.
5. Push the throttle trigger forward, which
will activate the brakes.
6. Hold the throttle open and roll the truck
on the ground. The truck should roll freely.
While it is still rolling , push on the brakes.
The truck should come to an immediate
stop. If these steps do not produce these
results refer to the linkage assembly setup
in this manual.
CHECKING THE CARBURETOR
Let’s check the carburetor linkage be-
fore you fire up the engine for the first time.
Pull off the air filter. Turn the transmitter
on first, followed by the truck.
With your finger off the throttle, which
is the neutral position, the throttle should
be almost closed, with an opening about 1/
32” (.71mm), as shown below.
Pull the throttle wide open and look into
the carburetor and see if it’s opening all the
way up. If you don’t see the gap shown be-
low, then adjust the “throttle trim adjustment”
on your transmitter according to the radio
manual, or adjust the linkage shown to you
earlier in this manual to achieve full throttle.
When everything is adjusted OK, turn
the switch off in your truck first, followed by
your transmitter. You must remember to turn
off your truck’s electronics every time in this
order.
Now, place the air filter back on your
carburetor and fasten it back down with a
new tie wrap.
