"Thanks Mathew. I am grateful for the input. The board in question appears to have been faulty. It is no longer working at all in the air, though it still looks ok on MP. I am a little surprised however by your comment about prop rotatation. I have…"
"I have been working my way through the Flite Modes and have struck a problem. Everything works fine in Stabilise, Loiter and RTL but I came horribly unstuck with Acro, about a week ago and today with Sport. Since the Acro crisis I have set my Geo…"
"I am back in the air again. The orange flash, next to the green one is only evident when powered by the USB and attached to Mission Planner. The arm, pause, disarm, cycle; in Mission Planner seems to be a feature of the programme. There is no disarm…"
"I think I have a new clue. I notice today, and had not noticed previously, that when I test arm, while attached to Mission Planner, it holds the armed state for about ten seconds and then disarms. Maybe it has always done that but maybe it signals…"
"I promised a picture but this is not what I had in mind. As you know I was working on PIDs and I read that this was best done in Acro mode. The model had been flown previously for about half an hour without any dramatic events. I was very confident…"
"Thanks for that. My GPS Unit is the Ublox 6M with a shield (skirt) It is mounted far aft and is about 60mm above the main power reticulation. I am thinking of fitting an earthed alloy shield above the power supply as extra insurance. At this point…"
I have just set up my first 2.5 with plenty of prompt inputs from Chris and John. Much gratefulness !!!It has flown and I am now working on the Pids. The first flight was WILD ! I have never seen such a shaking; but it has steadily improved and if…
"That's great. Many thanks for all of that.

"One hour later. I traced the fault on the original GPS. The red wire (centre) on the GPS plug (GPS end) had somehow backed out of its moulding. When carefully reinserted and re-fitted all was well except that todays satellites prevented arming. I…"
"Further Update
3 minutes later without having disconnecting the USB power to the APM 2.5 the system failed again with bad compass health. Very strange as the displayed alignment was correct.
So hard for a novice to understand. What are your…"

"UPDATE.
With the replacement GPS unit (no backplane) and updated firmware the unit checks out but the compass reads north as west nor west. In every other respect the APM 2.5 seems normal.
How should I proceed from here?

"Attached two pics. The source for the power mod and the GPS was Gadgets Infinite via Ebay.
I have fitted a GPS from Witespy (Ready to Fly Quads) This provides a 3D GPS fix but bad compass health. I have tried to recalibrate the compass but the…"

"I am not sure how I would know that. It is marked Power Mode V1. If the red wire (of the output wires is thought of as number 1) 2 = 0v: 3= 4.79v: 4=4.05v 5=5.31: 6=5.31v.

I think I have cooked my second Ardupilot. It worked perfectly on the GUI. Then I fitted the power module and the backplane on the GPS. Now the GPS does not light up, the HUD says bad compass health and it will not arm. Help please !
"I have down loaded the firmware. The HUD now shows Bad Gyro Health and it still will not arm. When I attempt to download the Data log files it gives the message Cannot Get Log List.
How do you see the next steps ?
Best wishes Peter"

"Not sure what the next step might be. Is there any way to test whether the problem, with downloading logs, lies is in the Mission Planner or in the APM board ?
Please advise
