the water well. If the winds are really high the Beaver can
still be fl own from water, but avoid turning it directly across
the wind. Otherwise, the wind can get under the wing and
fl ip the Beaver over. In the air, the only effect of the fl oats
is that the Beaver fl ies slightly slower.
Flying “normally” (using half-throttle for general cruising
and full-throttle only when required) the Beaver consumes
about 200mAh/minute for recommended fl ight times of
about 7 minutes with an 1800 mAh battery and about 8.5
minutes with a 2100 mAh battery. Flying more aggressively
using higher throttle settings, the current draw increases
closer to 260 mAh/minute for recommended fl ight times
of 5.5 minutes with an 1800 mAh battery and 6.5 minutes
with a 2100mAh battery.
To fi nd out for yourself how long you can fl y, set your timer
to a conservative 5 minutes. Fly until the timer sounds, then
land. Use a charger with a digital display to fi nd out how
much capacity it took to recharge the battery (indicating how
much capacity was used). To avoid over discharging your
LiPos use only 80% of your battery’s capacity, so multiply
your battery’s capacity by .8 to fi nd out how much you
have available. Compare the capacity used to 80% of your
battery’s capacity and adjust your fl ight time accordingly.
For example:
If using the recommended 1800 mAh battery,
your target capacity to use for a fl ight is 1440 mAh (1800 mAh
x .8 = 1440 mAh). If you fl y for fi ve minutes and it takes
1000 mAh to recharge your battery, you still have 440 mAh to
go before you should land, so adjust your timer to increase
your fl ight time accordingly until you reach your 1440 mAh
target. (You could also divide 1000 mAh by fi ve minutes
to fi gure a current consumption rate of 200 mAh/minute.
Divide 1440 mAh by 200 mAh/minute to conclude that you
can fl y for 7.2 minutes [7 min. 12 sec.]—but round down
to 7 minutes.)
When powering down,
always
unplug the battery from
the plane
before
turning the transmitter OFF.
It’s also a great idea to use a LiPo battery checker
(HCAP0275) to check the battery
before
each fl ight (to
make sure you haven’t inadvertently grabbed a discharged
battery) and to check the battery
after
fl ight to make sure
you haven’t over discharged your battery by fl ying too long.
A safe, conservative, minimum voltage is 3.65V – 3.7V per
cell right after a fl ight.
REPAIRS
Parts damaged beyond repair can be purchased separately.
The full replacement part list is printed in the front of the
manual on page 4. Often though, parts can be repaired
and you can get your Beaver back into the air with a little
glue and ingenuity.
The Beaver is made from injection-molded EPO (expanded
polyolefi n) foam which can be glued with just about anything.
Most people use regular CA. With CA no clamping is required,
but some prefer softer, more fl exible adhesives such as
white glue or canopy glue. These will require clamps or
tape to hold the parts together while the glue dries.
One fi nal note about fl ying your model. Have a goal or fl ight
plan in mind for
every
fl ight. This can be learning a new
maneuver(s), improving a maneuver(s) you already know,
or learning how the model behaves in certain conditions
(such as on high or low rates). This is not necessarily to
improve your skills (
though it is never a bad idea!)
, but more
importantly so you do not surprise yourself by impulsively
attempting a maneuver and suddenly fi nding that you’ve
run out of time, altitude or airspeed. Every maneuver should
be deliberate, not impulsive. For example, if you’re going
to do a loop, check your altitude, mind the wind direction
(anticipating rudder corrections that will be required to
maintain heading), remember to throttle back at the top,
and make certain you are on the desired rates (high/low
rates). A fl ight plan greatly reduces the chances of crashing
your model just because of poor planning and impulsive
moves.
Remember to think.
Have a ball! But always stay in control
and fl y in a safe manner.
GOOD LUCK AND GREAT FLYING!
