naza lite and new DX7 failsafe

[LHR Dave]

Hi,

I am having problems getting the failsafe (return to home) function programmed to the Naza M lite using the new Spektrum DX7. The function I am after is the one that sets the controller to failsafe (RTH) when signal is lost between tx and rx.

I am using the spektrum AR8000 receiver.

I have programmed this feature successfully using the same type of receiver on a spektrum DX6i. It was a good few months ago and i cant remember how i did this.

I have used the naza m lite software and all other functions are programmed correctly ie GPS , ATTITUDE, FAILSAFE(via toggle switch).

Please note that I am using the new DX7.

Is there someone out there who can advise me on this, all help is much appreciated.

Just have the throttle stick down Dave, when you bind the receiver

[LHR Dave]

I failed to mention this is for a DJI F450 Quadcopter.

Yes having the throttle stick down during binding will produce a failsafe.

But I require the quadcopter to go into failsafe (RTH) mode when tx rx signal is lost.

Apologies Dave, I did not read your post well enough, and you want RTH.

I suppose 90% of the time RTH works out, but where I fly, both incidents of RTH involved FPV flying down a dip in the landscape, and both finishing up in trees on the way back.

Both incidents obviously involved the pilots flying "out of line of sight" and too far out, so maybe got what they deserved

But fly "by the book" if you set RTH Dave

The BMFA Handbook quotes CAP 658 as saying " .....should have failsafe set as a minimum to reduce engine speed to idle on loss or corruption of signal" so it would appear that it is illegal in the UK to have the model set any other way than throttle at idle.

Far better that an MR returns home and lands safely than just drops out of the sky wherever it happens to be - as per Steve's link

I have to admit that deliberately cutting the RF output on the Tx for the first time, then watching an MR pause, turn round, come back and land does make you stand with a slightly silly grin on your face - and the hairs standing up on your neck!

And will be included in future update to 658 https://bmfa.org/News/News-Page/ArticleID/2127/Advanced-Failsafe-Options-for-Rotorcraft. Opps I see this has already been posted, apologies
