In any case, use a fl ight timer initially set to a conservative
time (4 minutes for example). When the timer sounds, land.
Use a LiPo checker to measure the resting (unloaded) voltage
when you land. The voltage should not be below 3.75V/cell.
When you charge the battery also note how much capacity
it took to recharge (indicating how much was used for the
fl ight). Strive to use no more than 80% of the battery’s capacity.
Adjust your timer according to the voltage and capacity used
for the fl ight.
You can also use the worksheet on page 24 to determine
optimum fl ight times based on your fl ying style and battery
capacity.
CAUTION:
Never run the motor on the ground for more
than a few seconds. Otherwise, you may overload the
motor, battery or ESC.
Battery Precautions
Charge and store LiPo batteries in a safe place!
Never leave charging LiPo batteries unattended!
Before mounting the motor and setting up the ESC and
battery, read the following important battery precautions:
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
.
This is a
SERIES
battery adapter
that connects two batteries in series.
(3-Cell) 3200 mAh
(2-Cell) 3200 mAh
11.1V
7.4V
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.
1. Connecting batteries in
“Series”
means to connect the
+’s to the –’s and the –’s to the +’s. This combines the
batteries’ Voltages, but the capacity remains the same.
This is a
PARALLEL
battery adapter that
connects two batteries in parallel.
(3-Cell) 1500 mAh
(3-Cell) 1500 mAh
11.1V
11.1V
These two 1500mAh batteries (both 11.1V) are being
joined in
PARALLEL
. The result will be one
11.1V, 3000mAh
battery.
2. Connecting batteries in
“Parallel”
means to connect
the +’s to the +’s and the -’s to the -’s. This combines the
batteries’ capacities, but the Voltage remains the same.
