IMPORTANT: If using multiple battery packs that are connected
with an adapter, never charge the batteries together through
the adapter. Always charge each battery pack separately.
Charge the batteries, then read the following precautions on
how to connect multiple packs for fl ying the model:
BATTERY PRECAUTIONS:
There are two ways to connect multiple battery packs: In
Series and in Parallel .
❏
1. Connecting batteries in “Series” means to connect the
(+)’s to the (–)’s and the (–)’s to the (+)’s. This combines the
voltages of the batteries, but the capacity remains the same.
These are two 3200mAh batteries (one 11.1V
and the other 7.4V). When joined in SERIES,
the result will be a 18.5V, 3200 mAh battery.
It’s okay to connect batteries with different voltages in
series to achieve the new, desired voltage.
This is a SERIES battery
adapter (GPMM3143)
that connects two
batteries in series.

2. Connecting batteries in “Parallel” means to connect the
(+)’s to the (+)’s and the (-)’s to the (-)’s. This combines the
capacities of the batteries, but the voltage remains the same.
These two 1500mAh batteries (both 11.1V) are
being joined in PARALLEL. The result will be
one 11.1V, 3000mAh battery.
This is a PARALLEL battery adapter (GPMM3142)
that connects two batteries in parallel.

NEVER connect battery packs with different voltages in parallel!
Only combine them in series. Otherwise, the batteries with
lower voltage will try to “equalize” with the batteries that have
a higher voltage. Current will fl ow from the higher voltage
battery into the lower one, essentially “charging” the lower
voltage battery pack. This situation will likely cause heat and
possibly a fi re.

Check the Control Directions
❏
1. Turn on the transmitter and receiver and center the trims.
If necessary, remove the servo arms from the servos and
reposition them so they are centered. Reinstall the screws
that hold on the servo arms.
❏
2. With the transmitter and receiver still on, check all the
control surfaces to see if they are centered. If necessary, adjust
the clevises on the pushrods to center the control surfaces.

3. Make certain that the control surfaces and the throttle
respond in the correct direction as shown in the diagram. If any
of the controls respond in the wrong direction, use the servo
reversing in the transmitter to reverse the servos connected to
those controls. Be certain the control surfaces have remained
centered. Adjust if necessary.
