you have own enough times and gathered enough data to
make the calculations for setting maximum ight time (see
the worksheet on page 32). When the timer sounds, land.
When you charge the battery note how much capacity it
took to recharge (indicating how much capacity (mAh) was
used for the ight). Strive to use no more than 80% of the
battery’s capacity.
You can also use a LiPo battery tester like the one in the
image (GPMM3205) to check the resting (unloaded) voltage.
The individual cell voltage should not be below 3.75V/cell
measured a few minutes after you land. Adjust your timer
according to the voltage remaining and/or capacity used
for the ight.
Use the worksheet on page 32 to determine optimum ight
times based on how much battery capacity was used for
a ight.
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
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 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. 4 V
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.
