much energy they store. A 550 mAh battery can supply 1
Ampere for .55 hours (about 30-minutes). A 1200 mAh battery
pack is about twice the size of a 550 mAh battery pack.
These are the battery packs recommended for the Tutor:
Panasonic 6-cell 550 mAh NiMh pack (GPMP0100) for
beginners due to its light weight.
Panasonic 7-cell 550 mAh NiMh pack (GPMP0101) for
advanced pilots who are capable of flying in slightly windier
conditions.
Chargers
The best type of charger to use is a peak charger, because it
charges the batteries until they are fully charged, then
automatically switches to a trickle charge mode. The Great Planes
ElectriFly
™ Peak Charger (GPMM3000) is suitable for nickel-
metal hydride batteries, NiCds and transmitter battery packs.
If you have another type of charger that is not a peak charger,
you will have to calculate the length of time it takes to charge
the batteries yourself, then turn the charger off when the
batteries are fully charged. Overcharging the batteries may
damage them. Before you can calculate the time it takes to
charge a battery pack, you first have to know the charge rate
you are going to use. Nickel-metal hydrides must be charged
at a rate of no more than 1/10 of their capacity. For the 550
mAh batteries recommended for the Tutor this would be a
charge rate of approximately 50 mAh. Divide the capacity of
the battery pack by the charge rate to calculate the charge
time. A discharged 550 mAh battery pack charged at 50 mAh
will take 11 hours to charge.
Charge rate/time recommendations:
Charge the 6-cell 550 mAh battery pack at 50 mAh for
11 hours.
Charge the 7-cell 550 mAh battery pack at 50 mAh for
11 hours.
Charge the 7-cell 1200 mAh battery pack at 100 mAh for
12 hours.
IMPORTANT: Monitor the temperature of the battery
frequently. If the battery becomes warm, disconnect it from
the charger.
A Hobbico R/C Multi-Charger (HCAP0100) is suitable for
charging the battery packs used in the Park Flyers.
Note: The period required to charge the batteries in the
examples above is for discharged batteries. If the battery you
are going to charge is not discharged (and you are not using
a peak-charger), connect it to the motor on your model. Run
the motor until the propeller is turning slowly, thus discharging
the battery.
Covering
There are several types of covering that may be used on the
Tutor, and a few that are not recommended. Use a covering
suitable for lightweight models. Top Flite
® EconoKote ® and
Coverite ™ Micafilm ™ are suitable for the Tutor. EconoKote is
similar to MonoKote ® (used on most regular-size sport
models), except EconoKote is lighter and does not shrink as
tightly, thus making it suitable for lightweight structures such
as that of the Tutor. EconoKote also has an adhesive on the
back which is activated by the heat of a model airplane
covering iron.
Coverite Micafilm is another covering suitable for lightweight
structures (and is the covering that is on the model featured
on the box label). Micafilm has fibers imbedded in the film and
is exceptionally strong, yet remains lightweight because it has
no adhesive on the back. Therefore, you must apply an
adhesive to the structure before application. Use Coverite
Balsarite
™ (COVR2500) for Micafilm. Do not use Balsarite “film
formula” to apply Micafilm.
Transparent MonoKote film is also suitable for covering the
Tutor, because it is lighter and does not shrink as tightly as
opaque MonoKote film. Opaque MonoKote film is not
recommended for the Tutor because it is too heavy and
shrinks too tightly for the structure to withstand.
Building Board
You will need a flat board to lay over your workbench that you
can stick pins into. The back of a 2' x 4' ceiling tile or a section
cut from a sheet of Celotex insulation board is ideal.

Must Make” section, the following is a “short list” of the
