One switch harness lead connects to the receiver’s “BAT” socket, another connects
to the battery, and the third lead is for convenient recharging of the battery through
the switch harness. Charging of the rechargeable battery through the switch harness
can only be accomplished when the switch is in the OFF position.
Use of “AA” NiCd or NiMH rechargeable cells is recommended. Do not use alkaline
cells for powering the receiver and servos. See the
SERVOS AND ACCESSORIES
section on page 16 for a full list of optional batteries and chargers.
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:
