Futaba 10J F4109 Data Sheet

Since the channel and operation mode used in training can be selected, the training difficulty can be set 

to match the student’s level. 

The trainer function can be used by connecting the instructor’s transmitter to the student’s transmitter 

using a special trainer cord (sold separately). Student operation is possible by instructor switch operation. If 

the student enters a dangerous situation, control can be immediately switched to the instructor.

● Four operation modes can be selected at each channel.
● The trainer switch is set to switch H.

When the trainer function is used, the snap roll function is automatically 
deactivated.

                                                    Use the trainer function under the following conditions:

● When the instructor uses a T10J transmitter, set the student’ s transmitter modulation to PPM (for 

conventional frequency transmitter). (When the student uses a T10J transmitter, the modulation 

mode does not have to be changed. A PPM signal is always output from the trainer jack.)

● Before flight always confirm that all the instructor and student channels operate normally as set.

● Always insert the trainer cord as far as it will go and take measures so that the cord will not work 

loose during use.

● Always remove the high frequency module of the student’ s transmitter. (For module type)

● Never turn on the student’ s transmitter power switch.

● FNC mode: The channel set to this mode can be controlled by the student using the mixing set at the 

instructor’ s transmitter. (Student settings are returned to their initial value in advance.)

● MIX mode: The channel set to this mode is controlled by mixing the instructor and student signals. 

Correction rudder is applied by the instructor. When this mode is selected, the student’ s rate is 

reduced to prevent servo overthrow. The student’ s rate can also be set. (The student’ s settings are 

returned to their initial value in advance.)

● NOR mode: The channel set to this mode is controlled by signals from the student’ s transmitter. (The 

instructor and student settings must be the same.)

●OFF mode: The channel set to this mode cannot be controlled by the student. It can only be controlled 

by the instructor.

However, channels not provided at the student’ s transmitter are controlled by the instructor regardless of the above 

settings.
When other models are selected, the trainer function is deactivated, but the channel settings remain.

● When the FUNC mode is set at the stick channel, helicopter stick operation training is possible even 

with a 4EX transmitter (4 channels for aircraft).

● Control by the instructor is possible by setting only the training channel matched to the student’ s 

level to the NORM mode and setting the other channels to the OFF mode.
