TECHNICAL NOTICE
FAILSAFE SETTING
IMPORTANT: Before installing the propeller, it’s
important for safety reasons to ensure that the
failsafe on the receiver is at the 0% throttle preset
position as indicated in the instructions below.
1. Install the AA batteries into the transmitter.
2.
Make sure the throttle
stick is in the minimum
position or 0% throttle.
3. Make sure the servo
reversing switch for
CH3 Throttle (located
on the front of the
transmitter) is in the
“R” position.
4. Power on the transmitter.
5. Plug in the battery to
the aircraft.
6. Press the LINK button
on the TR624 receiver
and hold for 2 seconds.
The red LINK light should
blink and then stay on.
The failsafe is now set. In
the event that the receiver
loses signal from the transmitter the throttle will revert to 0%.
If you would like to set the failsafe to a different position, refer
Throttle stick is in
the minimum position!
to the instructions below.
Always remove the propeller
from the aircraft before adjusting the failsafe.
FAILSAFE FUNCTION
The included Tactic TR624 receiver has a failsafe feature
which engages in the event that the radio signal from the
transmitter is interrupted. If radio contact is broken, this safety
feature causes the servos to automatically move either to
a certain position, or hold their last position to prevent the
model from moving in an erratic manner. Channels 1, 2, 4,
5, and 6 will enter a “hold” mode, whereby the servos will
lock in their last recognized position.
The servo or ESC 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% 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 and the propeller is removed.
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.
3. Move the Tx throttle stick to the desired position for the
throttle control to move if the Rx goes to failsafe.
4.
Press and hold the LINK button on the receiver, and the
Rx’s LED should blink twice. Release the LINK button,
and the receiver’s LED should turn on (stop fl ashing). The
Tx and Rx should now be linked, with the throttle failsafe
in the new position as set above.
NOTE:
If you replace the ESC with a different ESC which
has a signal loss feature, the pre-set failsafe position is
irrelevant as the signal loss feature will cease the throttle
operation if the signal is lost.
OPERATION / STARTUP
1.
When powering up the model to run the motor or fl y,
always
lower the throttle stick and turn on the transmitter
fi rst
before
connecting the battery to the ESC (similarly,
always disconnect the battery from the ESC before turning
off the transmitter).
