the batteries with the polarity indicated in the battery compartment. Press the battery
compartment cover back into place.
The Radio Transmitter (18) transmits a signal to the Airplane’s receiver.2.
The Transmitter is turned ON and OFF with the On/Off Switch located on the bottom3.
right side of the Transmitter-see Figure 5.
The Transmitter has 3 key functions used to control the Airplane-see Figure 5. Func-4.
tion 1 is controlled by the Main Control and turns the Airplane left or right. Move the
Control Stick to the right to make the Airplane go right, and left to go left. Remember
that when the Airplane is heading toward you the controls will be reversed.
Function 2 controls ying up or down. Moving the Control Stick forward will cause the
Airplane to descend, moving the Control Stick back will cause the Airplane to ascend.
Function 3 is used for speeding up or slowing down the Airplane Motors.
Attach the Ribbon (17) to the Transmitter Antenna.5.
The Transmitter has a Reverse setting that is used to change the direction of the6.
controls. For example, moving the Control Stick to the right turns the Airplane left if the
Reverse setting is engaged.
The trims are used to ne tune the function of the control stick. Before ying, set the 7.
Trims (elevator and rudder) to the center position. The trims will likely require addi-
tional adjustment in ight to allow the plane to y properly.
