the failsafe disabling process.
4. The LED will flash 2 times and then remain lit. The transmitter now does not control the receiver and the
failsafe has been disabled. You must now restart the receiver.
Mode III
- Short lit followed by a long dark period, repeated 3 times
sequence will repeat 2 times. Pressing the button in this mode will enable the failsafe function. If the button
is not pressed, mode III will be entered again.
If no button is pressed these 3 modes will repeat 10times, then end with 2 short LED flashes.

Enabling the failsafe

1. Turn on the transmitter with the antenna extended.
2. Turn on the receiver. The LED will blink 2 times. If the LED remains lit then the receiver is receiving
correct commands from a transmitter.
3. Adjust the sticks and switches on the transmitter to the position that you feel will best protect your aircraft
in the event of a loss of signal. Typically the throttle is decreased and a slight elevator input is required to
maintain a controlled glide slope. You should notice as you set the sticks and switches that the receiver is
responding indicating the transmitter and receiver are synchronized.
4. To set it up, press the scan button for 2 seconds, then release it. The LED blinks 3 times now (should it
blink 2 times, then press the button again for 2 seconds). While in mode III, press the button shortly to
start the failsafe enabling process.
5. The LED will flash 2 times and then remain lit. The transmitter now does not control the receiver and the
failsafe has been enabled. You must now restart the receiver.
During this setting step do not turn off the transmitter. Otherwise the receiver will not record the position
of sticks and switches and it will not retain a failsafe setting. Should this occur you will notice the LED
flashing twice and then going dark indicating that you will have to start the process over.
Caution:
1. Restart the receiver when the set up process of disabling or enabling the failsafe is completed.
2. While in Mode I, Mode II or Model III you can cut power to cancel the setting process. Do not cut power
in the process of locking receiver, disabling failsafe or enabling failsafe. Otherwise your receiver may be
damaged.
3. After enabling failsafe, please read just the transmitter settings of sticks and switches for the correct flight
conditions.

Installing the receiver

1. Plug in all the servos/ESC. Pay attention to the polarity of the connectors. Please consult the labels on the
case for the channel numbers and polarity.
Caution: If the polarity of the plugs is wrong, it can damage the servos/ESC.
2. If not using an ESC with a built in battery eliminator circuit (BEC), plug a 4.8V battery/switch harness
into any unused channel. If you are using all the channels for servos, use a Y harness to connect the
battery and servo to 1 channel.
3. Wrap the receiver in foam to isolate it from vibration and secure it in the aircraft with for instance a
rubber band.
4. Unwind the antenna fully. Do not coil or cut the antenna.
