If you decide you have no choice but to learn to fly on
your own, choosing the right place to fly your Whis-
per is of the utmost importance. Select your potential
flying field with the following considerations:
1) Look for a site that has a soft landing area. The
best sites are large grassy fields.
2) The fewer the ground obstructions the better. No
trees, buildings or large rocks should be nearby.
3) No people or houses should be nearby. While
R/C flying is generally safe, it can lead to harm or
injury. Do not try to fly your model if there are houses
or people nearby.
4) There should be no high-lines, telephone lines or
electrical lines anywhere near where you are flying.
If your plane accidentally does fly into wires of any
kind, do not try to retrieve it yourself. Serious injury
or even death could result. Contact the local electric
service company or police or fire department to help
you in retrieving your airplane.
BASICS OF FLIGHT
To begin you should know how your Whisper oper-
ates. First, there are four forces operating on a flying
aircraft: Lift, Weight, Thrust and Drag. The motor
will create thrust to overcome the drag. In times when
the engine is off, gravity pulling the plane down can
act as thrust. This is how the Whisper flies when the
motor is shut down. The wing flies through the air as
a result of the thrust and causes lift to overcome the
weight of the aircraft.
Controlling the Whisper
Flying is three dimensional, therefore, all aircraft op-
erate on three axis: roll, yaw and pitch. Roll is the
wing tips raising and lowering. Yaw is the nose mov-
ing from right to left. Pitch is seen as the nose mov-
ing up and down. Maintaining flight is the act of
overcoming weight and drag with lift and thrust while
properly controlling all three axis.
Choosing the Whisper greatly simplifies these activi-
ties. First, it takes very little thrust to overcome the
drag. So much so that the Whisper will glide and
thermal without any motor power at all.
Second, the wing is a high lift design that easily over-
comes the weight which means that the Whisper can
fly very slowly.
Flying the Whisper
Check the controls. Make sure the throttle, elevator
and rudder are all working properly. The flight bat-
tery should be fully peak charged and ready to go.
First, let's lay out the basic maneuvers that will make
up your training flights.
1) Launching
2) Climb-out
3) Level Flight
4) Standard Turns
5) Descent
6) Landing
All flight is based on these few tasks. Here, we've laid
them out in the same order they will be during flight.
Learn these basics and you will soon fly your Whisper
with great success. Now look at each maneuver indi-
vidually. Before flight, make sure you are completely
familiar with the functions of the transmitter including
all controls and trim tabs.
Launching and climb-out requires that the plane be fac-
ing directly into the wind. To launch the airplane, lightly
grasp the fuselage in your hand, between your thumb
and forefingers, just below the wing, at the center of
gravity. Hold the plane at about shoulder level, apply
full power and solidly toss the airplane straight ahead
and level. Do not throw it hard or
up at an angle.
