Battery Precautions - GREAT PLANES PT-19 Instruction Manual

measured with a volt meter after you land. When you charge
the battery 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 flight times based on your flying 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.
Range Check
Don't forget to perform your usual ground range checks as
written in the instruction manual that came with your radio
system to be certain it is operating correctly.
AMA SAFETY CODE
Read and abide by the following excerpts from the Academy
of Model Aeronautics Safety Code. For the complete Safety
Code refer to Model Aviation magazine, the AMA web site
or the Code that came with your AMA license.
General
1) I will not fl y my model aircraft in sanctioned events,
air shows, or model fl ying demonstrations until it has
been proven to be airworthy by having been previously,
successfully fl ight tested.
2) I will not fl y my model aircraft higher than approximately
400 feet within 3 miles of an airport without notifying the
airport operator. I will give right-of-way and avoid fl ying in the
proximity of full-scale aircraft. Where necessary, an observer
shall be utilized to supervise fl ying to avoid having models
fl y in the proximity of full-scale aircraft.
3) Where established, I will abide by the safety rules for the
fl ying site I use, and I will not willfully and deliberately fl y my
models in a careless, reckless and/or dangerous manner.
5) I will not fl y my model unless it is identifi ed with my name
and address or AMA number, on or in the model. Note: This
does not apply to models while being fl own indoors.
7) I will not operate models with pyrotechnics (any device
that explodes, burns, or propels a projectile of any kind).
Radio Control
1) I will have completed a successful radio equipment ground
check before the fi rst fl ight of a new or repaired model.
2) I will not fl y my model aircraft in the presence of spectators
until I become a qualified flier, unless assisted by an
experienced helper.
3) At all fl ying sites a straight or curved line(s) must be
established in front of which all fl ying takes place with the
other side for spectators. Only personnel involved with fl ying
the aircraft are allowed at or in the front of the fl ight line.
Intentional fl ying behind the fl ight line is prohibited.
4) I will operate my model using only radio control frequencies
currently allowed by the Federal Communications Commission.
5) I will not knowingly operate my model within three
miles of any pre-existing fl ying site except in accordance
with the frequency sharing agreement listed [in the
complete AMA Safety Code].
9) Under no circumstances may a pilot or other person
touch a powered model in fl ight; nor should any part of the
model other than the landing gear, intentionally touch
the ground, except while landing.
The PT-19 doesn't exhibit any particular characteristics that
you need to be aware of ahead of time. The PT-19 fl ies quite
honestly and has no unusual tendencies. Same as any tail
dragger, takeoffs and landings are usually smoother and
more controllable in short grass, but takeoff from paved
surfaces is fi ne too – you just have to be a little "quicker"
on the rudder to optimize yaw control with the tail gear.
Landings usually work out a little better by "dragging" in
the PT-19 with a few clicks above idle of throttle. Just let
the PT-19 descend into a shallow, consistent sink rate and
she'll settle right in for landing.
Have a ball! But always stay in control
and fl y in a safe manner.
GOOD LUCK AND GREAT FLYING!
