Tested mine before I had the GPS and it did indeed come down slowly, touch down softly, and stop the motors.

I agree and would add that on some days failsafe auto-land does a better job than me

The 1st time I tested the RTH, the auto-landing was so soft that the Naza didn't detect it, and it gently bumped 10cm, like 3 or 4 times until the bump was hard enough so it realized it was on the ground and stopped the engines :]
Or maybe it computed that it had already lost enough altitude, from the GPS or whatever...

First Flight with out issue

Well I finally figured out I had gains all set to 100% and changed to factory recommendations for 550. Wow what a difference it almost flew hands off. I still have some drifting to work on I guess tweaking gains maybe, back to manual and this forum.
You gents (gals maybe) are the best, at least I out of starting blocks for learning curve.
It was so cold here I was flying from dinning room and negotiating trees (lots) in back yard and did not take any bark off!

Ok so I flashed my 9x to er9x. It works but haven't flown it. Just hate that I am having issues with setting the 3 pos to go to manual mode. I have gps-atti-failsafe and I cant get it away from the failsafe. AARRGGHH! I would hate to think that I would be flying through trees or a building or under a flock of nearly extinct birds and I accidentally hit the switch al the way down and take out the last 3 birds of that species on the planet...whoa is me! lol

Here's what you do with a Spektrum/Jr or a Futaba transmitter:
I can't speak for one like yours...

On the 3pos switch Atti is center with GPS and Manual being at the ends.
Use subtrim for your switch channel to get Atti in the center.
It IS permissible to use subtrims on switches with Naza!
Then use travel adjustment to set the endpoints to GPS and Manual.
Do this while connected to Assistant and you can visibly see the correctness of your adjustments.
After losing Failsafe on the 3pos switch, you'll need to investigate a mix on another switch to force the U channel into Failsafe.

Programming your individual aileron, rudder and throttle channels and circumventing the NAZA doesn't seem very sensible to me.
When my FM receiver (big mistake) lost signal at 100 feet out and 50 feet high and no failsafe available on the rX and none set on Naza the machine basically flew away at a pretty decent clip, maintaining altitude, till it ran into some trees about 400 feet away. If the trees hadn't been there it probably would have flown till the batteries wore out.

In order, from the safest to the less, I'd say :

Naza + GPS + Good TX/RX + RTH failsafe
Naza + GPS + RTH failsafe
Naza + Receiver with failsafe + Auto-landing
Naza + Receiver with no failsafe + A good bike or running shoes, and good cardio

RX location on DJI 550

You all have convinced me to upgrade to AR8000 so I have fail safe.
On a 550 where is best place to mount RX and remote.
I am thinking RX next to Naza and remote on bottom side?
