TRAINER FUNCTION
The trainer function is a very effective way for training students. To use it, the special
trainer cord (sold separately) is necessary.
The special trainer cord can be connected to SKYSPORT4, FF5, SKYSPORT6, 7U series,
8U series, and PCM1024Z series transmitters.
OPERATING
INSTRUCTIONS
*Connect the student and instruc-
tor transmitters with the trainer
cord.
Instructor side:
Turn on the power switch and extend the
antenna to its full length.
When the trainer switch is not pressed,
the instructor has control.
When the trainer switch is pressed, con-
trol is transferred to the student.
Student side:
Never turn on the power switch.
WARNING
Never turn on the student trans-
mitter power switch.
Turning on the power switch will cause
interference and a crash.
Set the student and instructor
transmitters to the same settings.
For example, if the direction of operation
is reversed, control will be lost and the
plane will crash.
The opposite side can only use an
FM (PPM) type transmitter.
If the modulation method is different, con-
trol is impossible.
