6. The LED on the teacher’s Tx will fl ash 3 times to indicate
it has become bound with the student’s Tx.
7. The teacher can then release his trainer switch.
8. Once both transmitters are bound together, power can
be applied to the receiver to prepare for fl ight.
When the training session has ended, with the model on the
ground and all power removed from the model, place both
transmitters within 1 meter of each other and simply turn the
power switch for both transmitters to the OFF position. This
will terminate the wireless link between both transmitters. If
additional training will be performed again, return to step 1
above to re-establish the wireless link between the teacher
and student’s transmitters.
TR624 RECEIVER & FLIGHT
EQUIPMENT INSTALLATION
(if applicable)
RECEIVER (Rx)
Mount the receiver as specifi ed in the model’s instructions.
It’s important to keep the Rx as far away from the engine/
motor, servos, and ESC and other electronic items as possible.
To prevent the Rx from becoming damaged, it might be
acceptable to mount it inside certain models using Velcro
®
. In
certain cases, wrapping the Rx with foam rubber can help to
prevent damage from occurring due to vibration, but foam
rubber can prevent adequate airfl ow from passing over the
receiver in warm environments which might not be
recommended. Additional Tactic TR624 receivers can be
purchased from your local retailer (part number TACL0624)
to work with this TTX404 transmitter.
IMPORTANT!
Always make sure that power
is applied to the transmitter BEFORE applying
power to the receiver and servos, and that
the throttle stick is at minimum (idle) position.
Failure to do so could result in the model becoming
uncontrollable and cause a safety hazard.
BIND THE RECEIVER
TO THE TRANSMITTER
For proper operation it’s necessary to “bind” the Tx and Rx
together electronically. This ensures sole communication
between the two, and prevents other transmitters from being
able to control the receiver.
1. Turn on the Tx.
2. Apply power to the Rx.
3. If the Rx LED fl ashes once and then stays on, the
Rx is already bound to the Tx and you can skip to
the next section. Otherwise, insert a small diameter
screwdriver through the hole marked “BIND” and press
the pushbutton until the Rx LED glows red and then
turns off after about one second.
4. Release the “BIND” button.
5. If the binding is successful, the Rx LED will fl ash once
and then remain ON.
6. Test for proper Tx / Rx functionality in the next section.
If the radio doesn’t appear to have become properly
binded, repeat steps 1– 6 above.
FAILSAFE FUNCTION
The included TR624 receiver has a failsafe feature which
engages in the event that the radio signal from the transmitter
somehow becomes interrupted. This safety feature causes the
servos to automatically move either to a certain position, or hold
their last position so to prevent the model from moving in an
erratic manner. Channels 1, 2, and 4 will enter a “hold” mode,
whereby the servos will lock in their last recognized position.
The servo connected to channel 3, normally being the throttle
control, will move to a pre-set position. The factory default
failsafe position for channel 3 is to move to 0% full throttle.
Motor/prop movement should stop if the receiver loses signal
from the transmitter. The throttle servo’s failsafe position can
be manually re-set to any other position if desired, as follows:
IMPORTANT NOTE:
Before manually resetting the failsafe,
make sure the servo reversing switches are in the correct
position for the application.
1.
Apply power to the Tx and Rx.
2a.
If using an ESC, do NOT arm the ESC. Do NOT attempt
to adjust the throttle’s failsafe position if the ESC is armed.
2b.
If using a gas or glow powered engine, do NOT attempt
to adjust the throttle’s failsafe position while the engine
is operating.
