Tactic TTX650 6-Ch SLT Computer - Manual (Page 37)

The failsafe function is not controlled by the TTX650 transmitter itself, but rather by
the Tactic receiver. Tactic’s stand-alone 2.4GHz receivers have a failsafe feature which
engages in the event that the signal from the Tx somehow becomes interrupted. In such a
case, channels 1, 2, 4, 5, and 6 (all but CH3 throttle) will hold their last received position.
Throttle channel 3 can move to a pre-set position. The factory default failsafe position for
channel 3 is to move to 0% throttle. The throttle’s failsafe position can be manually set
to any other position if desired, as follows:
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 throttle stick to the desired throttle failsafe position.
5. Press and hold the receiver’s “Bind” button. The Rx’s LED should blink twice.
Release the Bind 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 (no trainer jack - no cable required!).
The TTX650 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: TTX650 Student’s radio: Tactic TTX404 or TTX600
1. Link the teacher’s TTX650 to the Rx inside the model, and then remove power
from the Rx.
2. In the TTX650 TRAINER screen described on page 18 select which channels
NOT to transfer to the student while training, and select a switch to control the
trainer function. Switch F is the recommended switch for training purposes.
