all channels can be set to move to a specifi c position – or only throttle channel 3 can be custom set (with
all other channels holding). If using the Tactic TR825 receiver, beware that ALL channels can be set to
specifi c positions. Be alert to the position of all channels.
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, 410, 600 or 610
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 12, 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 student’s
power switch.
