Hello,

As many of you may know that the spectrum recevier has a default failsafe function. When the signal is lost, all channels will output the transmitter's sticks position when it was binded. However, for the Naza flight controller, it cannot detect the signal loss becasue the receiver will be in failsafe and continue output the signal. What makes it even worse is that I usually put the throttle stick to the lowest position when binding, so the receiver will output the lowest throttle commend to the flight controller, and therefore the quad will drop like a rock!

Can anyone help me to setup the transmitter/naza to enable the failsafe function of naza? So when the signal is lost, my quad could return to home rather than drop like a rock.

Make sure your rx supports programmable failsafe. Only Ar7000 v2 or above support this feature.

1 You have to setup all switches to the correct position before powering the TX (put the throttle in the middle also).
2 You have to put in bind mode your receiver
For orange RX you have to remove the bind plug after that
For Spektrum you have to do that twice times (one with the plug one without for failsafe and fail crash)

3 Press the bind/trainer button and power on your TX.

Now the receiver save this setup as the default setup when receipt is out of range and send the memorized setup to the flight control board.

Correct but he still needs an rx that supports programmable fs. The correct way is to boot the rx with bind plug, then remove bind plug.  Then turn on radio while pressing the bind with all switches in the desired fs position.

Spektrum AR6260 also has preset failsafe option

Cool.. haven't used spektrum for about a year now..

Please send me your file link. I can not see it attached.
