Batteries must be kept warm when flying in cold weather or else they may not provide enough
power for flight. It is recommended to keep them in a warm car with the heater on between
flights while charging. An insulating pouch or wrap for the batteries is recommended to keep
the batteries warm in flight. An inexpensive heating pad or small electric blanket adapted to
run off a cars cigarette lighter is one possibility for keeping lithium batteries warm between
flights.
For fire safety the batteries should be placed in a nonflammable container if inside a car while
charging.
Never put the battery and charger near flammable material while charging as this may cause a
fire. When modifying or disassembling batteries never use a sharp knife or puncture the cells
because you may short circuit the battery and there is an explosion risk. Never dispose of
batteries into a fire because they can explode or emit noxious gases and heavy metals.
If you are using lithium polymer batteries USE LITHIUM CHARGER ONLY! Refer to
manufacturers safety warnings.
Lithium batteries MUST ONLY be charged by a lithium battery charger and
manufacturers precautions must be adhered to.
Never leave batteries charging unattended!

13) Flying and Operating Tips:
-- Please be aware of the gears moving at high speed and treat this model with caution
when running up the motor! --
Once you have your model fully assembled with the radio gear installed and the battery
charged you are ready to fly. The Slow Hawk 2 is park flyer, and at low throttle setting a slow
flyer, however weather-wise it should be treated like a conventional slow flyer. Completely calm
conditions are optimum for the the best flight performance. It can fly fine in a smooth steady
wind from 5-7 mph but gusty conditions are to be avoided. Due to its ultralight design and
construction it can be blown about and tumbled by choppy air. We recommend you save your
Slow Hawk for calm days and try to fly it in the calm air of the early morning or late evening
hours. In those conditions you will be delighted with the way it flies.
ADJUSTING CENTER OF GRAVITY (C.G.):
The Slow Hawk is designed with a layout that basically does not allow for much misplacement
of its components thereby insuring the proper CG range is maintained with little concern as long
as the recommended radio equipment is used. The degree of adjustment of the CG is really left
only to mounting the battery either for or aft on the fuselage and this is up to the user to select
according to flight characteristics.
As a rule of thumb, start with the battery pack mounted to the velcro strip on the fuselage
towards the rear
area
of the velcro strip. Adjust as needed.
As stated, as long as the recommended micro radio gear is used and the battery is mounted in
its proper place, the CG falls in place, basically
around
the front post where the wing sail
