Has anyone used the condition DO_DISTANCE? What exactly triggers that?

@Andrew re issues with position hold on AC3.0.1, could you come post the logs on the AC3.0.1 release thread?

3.0.1
Have had brilliant results with this,
But !
Couple of days ago while testing pos hold my quad went off on its own, no response to controls, went up to 20 odd mts then wandered over to where my car was parked, then shut down (just missing my car)! Also just test hovering quad very twitchy, motors pulsing, like p settings way too high, but they not altered from before, any ideas ?

Failsafe & Turnigy 9X:  OK I'm a beginner, still Googling before my first flight. I thought the Turnigy 9x was popular/good/cheap/etc, but have found it does not provide any failsafe functions.

Here's my approach around this, rather than switching to FrySky.

I'm using the 900MHz telemetry system, & running Mission Planner on a small laptop. I read it has a further range than the 2.4GHz Turnigy. So I plan to monitor the battery voltage and whatever else I need, with the telemetry and hopefully do any needed 'recovery' actions.

A question: Does the Arduflyer 2.5 & the MP & the Turnigy 9x allow monitoring the signal strength of the 2.4GHz signal. I think the RSSI is the telemetry signal strength?

Any info appreciated

Just did CLI test on GPS and it seemed to report it was fine.

Did CLI test on compass and report said "Not Healthy".

I just noticed/confirmed, Mission Planner Flight Data page gives message, "No GPS". I had GPS when I first loaded firmware and flight data showed it locked on my house - 3 days ago...

Tx in mode 2.

No signal from Rx is recognized by the board unless I'm in ESC calibration.

I can calibrate ESCs, but can't arm the system afterwards. Also, I now don't get a GPS response.

Just swap over the cables from roll and yaw.

What mode is your Tx in?

Comment by Dan Skaggs on July 4, 2013 at 6:45pm
Mike, Tx is set to acro. Throttle bar was only moved in MP by throttle, but Rudder was moved by roll & roll was by rudder. That's why I initially thought receiver wires were wrong, but they checked out right (see Logan's comment below). Now I can't get board/ESCs to initialize.
Comment by Dan Skaggs on July 4, 2013 at 6:38pm
Bo, good thought, but I read the same note about trimming throttle - tried it but no change.
