Autotune -> autotune multiple times? Are the PIDS refined more and more?

Hi folks...

Just wondering...

If I run autotune a 2nd time, does Pixhawk start over from scratch using some default PID values as a starting piont?

Or does it start the 2nd autotune flight using the current (already autotuned) PID's? And if so, what the

Edit Waypoint File

Is there a way to go back into the interface where I create Auto WP Survey (grid) and modify an existing waypoint file? For example, if I have created a WP file where the speed is 3M per second, and I changed the Angle (deg) to something other than t

Altitude Hold Troubleshooting

So I am flying my vario helicopter in stabilize mode great.  I am venturing into AltHold and am seeing some strange behavior. 

I noticed that my BarAlt and Alt were not matching up.  So I reduced the INAV_TC_Z value which helped a lot.

How to exit Follow Me mode

I have follow me mode working.  I get the copter in the air in loiter and then enable the mode through mission planner.

GPS with similar performance to uBlox NEO-M8N

Spline waypoints missing from Mission Planner

I did a new installation of the latest (v 1.3.28) MP on a PC and SPLINE_WAYPOINT isn't listed in the command drop down list.  Further, if I check the Spline box before clicking on the map, it drops a waypoint at 0,0 Lat/Long.

Hi,

I'm wondering where I can buy a spare cable with mini JST SH 1.0mm 6 pin female to female ?

It is the cable w. 6 wires that connects, for example, the old GPS style socket  from the 3DR APM 2.5 board to the Ublox Lea GPS (six wires) and I found it

Bad AHRS

Attached are the logs of a power up with "Bad AHRS" message. It usually clears but this time it did not. This is a new Pixhawk direct from 3DR and has never been flown.

What should I do to resolve this message?

Do I have something configured incorrectl

When arming, all the motors spin up to high rpm immediately with no response to the position of the throttle lever.

After setting the value (mot-spin-armed) to zero, the motors does not spin anymore when ar
