Other Valuable Optic Transmitter Functions
FAILSAFE FUNCTION (FAIL)
The use of the Failsafe function is pre-program a setting for your aircraft to assume should the
loss of signal from your transmitter occur in flight. This loss of signal may be due to
interference from other sources. Failsafe mode will not assist you in the event of a power loss
by the on-board battery. On the Optic 6, the use of Failsafe can only be done using the Hitec
QPCM receiver and you must program your Optic 6 to use the QPCM mode of signal
transmission when making the initial model set-up.
The settings you program in may be to reduce the throttle and deploy flaps to slow the model in
flight. All channels will move to the Failsafe position upon any loss of signal from the
transmitter. The receiver will regain full control when the signal is restored and normal flight
will continue.
To program in the Failsafe is quite fast and easy. Let’s program a common sport model using
four channels. Again, only the Hitec QPCM receiver, Model No. HPD-07-RH, is capable of
using the Failsafe option. The model now being programmed must use the QPCM mode of
transmission and to program this, depress both the UP and DOWN Edit keys while turning the
Optic 6 transmitter power ON. Use the Up or DOWN Edit keys to scroll to the transmission
mode screen, which has a default of “PPM”. By pressing the Left Cursor key once, the mode
will change to QPCM. Now turn the Optic 6 power switch OFF. With the Optic 6 transmitter
ON once again (in the normal power ON mode) and the receiver power ON, enter into the
Menu Function screen of the Optic 6 by depressing both the UP and DOWN Edit keys at once.
The default screen will show the “FAIL Inh” message. By pressing the CLEAR key once, you
will activate the Failsafe mode. Now, move your control sticks to the position you wish for the
control to move to if you experience a loss of signal and hold the sticks in this position. While
holding the control sticks, press both the (-) and (+) Data keys at once and the positions you
have selected are placed into the failsafe memory of the receiver. A double beep heard when
you pressed the Data keys will confirm the position is given. Now, turn the Optic 6 transmitter
Off and then back On once again. When the transmitter was turned Off, the servos should have
moved to the Failsafe position. If so, you have successfully completed programming the
Failsafe option. You may change the Failsafe position at anytime using this same procedure.
