The factory default failsafe position for channel 3 is to move to 0% throttle. Refer to the instructions with
the receiver or see
www.tacticrc.com/receivers
for details.
1.
IMPORTANT: make sure the servo reverse settings for all servos are in the correct position for the
application.
2.
Apply power to the Tx and Rx.
3a.
If using an ESC: do NOT arm the ESC, or attempt to adjust the throttle’s failsafe position if the ESC
is armed. NOTE: If you’re using an ESC which has a signal loss feature, its pre-set failsafe position
will be irrelevant as the receiver’s failsafe function will cease the throttle operation if the signal is lost.
3b.
If using a combustion engine: do NOT attempt to adjust the throttle’s failsafe position while the engine
is operating.
4.
Move the Tx sticks to the desired failsafe position.
5.
Press and hold the receiver’s “Link” button. The Rx’s LED should blink twice. Release the Link button,
and the LED should stay on continuously. The Tx and Rx should now be linked, with the throttle
failsafe in the new position as set above.
Two Tactic brand transmitters with trainer capabilities can communicate with each other by wireless means
for teaching a student how to fl y. The TTX850 can be confi gured for wireless trainer function with any other
Tactic brand transmitter, but is not compatible with wireless trainer systems in other brand transmitters.
Once linked for training, make sure both transmitters are kept within 15 feet of each other at all times.
IMPORTANT!
Before fl ying the model in training situations it’s very important to make sure
all channel reverse settings and trim adjustments on the teacher and student transmitters
match! Otherwise, the model could suddenly veer in an unwanted manner when the teacher’s
trainer switch is activated. Proper matching of the student and teacher’s Tx settings should
ensure that no unexpected movements occur when the trainer switch is pressed. This is especially true of
the throttle control!
Teacher’s radio TTX850 - Student’s radio Tactic TTX404 or TTX600
1.
Link the teacher’s TTX850 to the Rx inside the model, and then remove power from the Rx.
2.
In the TTX850 TRAINER screen described on page 10, select which channels to NOT be transferred
to the student while training, and select a switch to control the trainer function. Switch F is the
recommended switch for training purposes.
3.
Turn the teacher’s Tx off.
4.
Pull the TTX850 trainer switch and
hold it in this position
while turning the power switch on. The
“searching” message should show on-screen.
5.
Move the student’s transmitter to within 3 feet of the teacher’s transmitter and turn on the TTX404/600
power switch.
6.
The TTX850’s “searching” screen should disappear. The teacher can release the trainer switch. If the
TTX850 doesn’t identify the signal from the student’s radio a “NO SIGNAL” message will show.
7.
Once linked, move the throttle stick on both transmitters to minimum. Turn the Rx power on and
make sure only those channels selected for transfer to the student are transferred when the TTX850
trainer switch is defl ected. Ensure the teacher can regain control of all channels when the trainer
switch is released.
8.
Perform a complete range check before fl ight.
