Trim Levers –
The trim levers are used to make small,
in-fl ight
adjustments
to the assigned control surface’s neutral position. When fl ying, adjust the
levers as necessary to “fi ne-tune” the model’s fl ight path so it will fl y straight-
and-level when the control sticks are neutral (“hands-off”).
Right control stick (3-channel operation) –
Controls the servos connected
to
channel 1
and
channel 2
on the receiver (typically, for 3-channel models,
the rudder and elevator). Pulling the stick back (toward the pilot) should
cause the elevator to move up, pushing the tail down and pitching the nose
upward (technically called “pitch” control). Moving the stick to the right
should cause the rudder to move right, causing the nose of the model to
turn to the right (technically called “yaw” control). The opposite should occur
if the stick is moved the other way. Note that properly designed 3-channel
(“rudder-only”) models have signifi cant wing dihedral. This will allow the
model to enter a bank with rudder control alone (simulating the effect of
ailerons on 4-channel models).
Left control stick (3-channel operation) –
Controls the ESC connected to
channel 3
(throttle). Pulling the stick back (toward the pilot) should turn the
motor off and moving the stick forward will advance the motor speed.
Right control stick (4-channel operation) –
Controls the servos connected
to
channel 1
and
channel 2
on the receiver (typically the ailerons and
elevator). Pulling the stick back (toward the pilot) should cause the elevator
to move up, pushing the tail down while pitching the nose upward (technically
called “pitch” control). Moving the stick to the right should cause the right
aileron to move up and the left aileron to move down, causing the model to
enter a banked turn to the right (technically called “roll” control). The opposite
should occur if the stick is moved the other way.
Left control stick (4-channel operation) –
Controls the servos connected to
channel 3
and
channel 4
on the receiver (typically the throttle and rudder).
Pulling the stick back (toward the pilot) should turn the motor off. Moving the
stick to the right should cause the rudder to move right, causing the nose of
the model to turn to the right (technically called “yaw” control). The opposite
should occur if the stick is moved the other way.
