Radio fail starts mission

[Patnet]

I'm having a peculiar action. I set PH and the Android app confirms it verbally. I then cut the radio, the AQ4 performs Stage 1 hold. At stage 2 the app says it's navigating to the first way point and then moves away from PH, which should be Home, right?

I have the Aq set to failsafe hold then rth and then land. Any ideas?

If you don't set home position specifically before engaging PH, then wherever you first engage PH becomes "home." And yes the failsafe mission should be directing it within 2m (IIRC) of home position. Does it stop fairly soon, or just keep going? Also what is your GPS HAcc during all this?

In fact the failsafe event triggers a short mission: from the actual coordinate to the home point and the landing.

How did you test it? Bench or real life?

I don't give it time to escape. I pounce on it. GPS is 3D. Wondering if this was a known issue or anomaly?

The first thing that you need to have is a good 3D GPS lock. The only way to be sure the GPS has a good lock is to test and see how well it flies in altitude position hold. If your multicopter hovers well in one place then try RTH by setting home then fly the multi a few meters away and use the return to home switch. If that works well you can try return to home with progressively longer distances.

Failsafe will work when flying in manual and or altitude position hold flight mode. Switch off the Tx and the multi will hold it's position for 20 seconds and then move to the last position that you set home.

I have just one three position switch, so I'm using it for Normal, AH and Mission. RTH I intend to acomplish by switching the radio off. However when I do switch to Mission in the PC version of the software there's no verbal indication like there is with AH. Is that correct?

[LPR]

I don't remember a response when switching to mission except for the waypoints being announced.
You can use one switch to set home and another for return to home.

Larry, I would really like to set one switch as return to Home. I don't see how though. I have Flight Mode on Ch 6 with manual/hold ap/mission/ I have one unused channel (ch 5). How would I make the three position Home Action return/normal/set home to normal/return, or nornal/return? It's a three position radio value. I only have available two position switches and one spare channel.

Thanks for everyone's help. My bird is flying nice and stable right now. Most problems I'm encountering are poor piloting.

Depending on which Tx you have it's usually quite easy to mix two switches to one channel. Look for a youtube video, a manual or this forum for help.
