PREPARING TO RUN YOUR RAIL bRUShLESS Off-ROAD bUGGY
q
With the ESC On/Off switch in the 'OFF' position, make your battery connections. The
battery packs should be connected in series. To do this, plug one end of the jumper
you made into the positive (red) connector on one battery pack, then plug the other
end of the jumper into the negative (black) connector of the second battery pack.
Next, plug the free connector from each battery pack into the ESC battery connectors,
making sure that the polarity is correct. Positive (red) to positive (red) and negative
(black) to negative (black). For more information, see page 49.

Dual Battery Pack Installation and Power Connections
q
Solder two 4mm female Bullet connectors onto each battery pack (for reference, see the photo on the previous page). Connectors
for one battery pack are included. You will need a second pair of connectors (available separately) for your second battery pack.
If you're using hard-case Li-Po car battery packs with preinstalled 4mm female Bullet connectors, you can skip the procedure above.
q
Make a jumper using a short length of 12 AWG silicone wire [approximately
100mm ~ 127mm (4" ~ 5") depending on the battery packs used] with one 4mm male
Bullet connector soldered onto each end. This jumper will allow you to connect your
two battery packs in series. Alternately, you can purchase a preassembled jumper
(P/N 145795). For more information, see the Option Parts List on page 70.
q
A spacer block is installed in the battery holder to stagger the two battery packs so
that they can be stacked on top of each other without interfering with the battery
leads. If using two hard-case Li-Po car battery packs with the battery connectors in
the top of the battery, unsnap the spacer block from the back of the battery holder
and reinstall it at the front of the battery holder. This will allow the batteries to be
installed staggered with the battery connectors toward the back of the battery holder.
Install your battery packs with the battery leads toward the BACK of the battery
holder. In addition, the battery packs should be staggered so that the connectors
can be plugged into each battery pack without interference.
q
Slide one battery pack into the battery holder, then slide the second battery pack into
the battery holder on top of the first battery pack.
q
Pull the two battery retaining straps tight to hold your battery packs securely in place.

Checking the Steering and Throttle Controls
IMPORTANT:
Before checking the steering and throttle controls, we recommend placing the Rail on a car stand so that the wheels
are off the ground. This will ensure your safety and the safety of your model while testing the throttle control.
If your model features a 2.4GHz radio control system, your transmitter and receiver have already been paired and should work
correctly. If not, bind your transmitter and receiver again following the procedures in the radio control system Operating Manual.
q
Turn your transmitter 'ON' and verify that it has sufficient power.
q
Turn the ESC switch 'ON'. The ESC and motor heat-sink cooling fans will power up,
the Status LED will flash red twice and turn solid orange, then the ESC will beep 3
times. This indicates that the ESC is operating correctly and the motor is armed.
The Status LED is visible through the side frame, near the bottom of the ESC.
