Auto Tune Resultant PIDs
The I value is a bit suspicious, it flys perfectly (if a little to aggressive)
Is this an expected result from Auto Tune ?

Compass Calibration
I've calibrated the compass (using methods in various YT videos) several times. Each time I get different offsets for the calibration even though the machine hardware and location remains the same.
On every flight I get EKF warning of compass differen

I'm not certain this is the correct place for this question but here goes..
After a crash and identified ESC fault All ESC have been replaced on the Octo.
The replacement ESC are Opto so the pixhawk is being powered purely by the pixhawk power module.

First field trip since update.
After doing calibrations in the field first flight was going well until about a minute in. I was in loiter hovering level, just tilting the camera down when the back of the Octocopter dipped violently, lost lots of heigh

No problems in flight to mention but got a strange problem on the gimbal (nothing to do with the Pixhawk).
whilst looking at the logs I noticed more vibration than normal (at least from what I can remember) The soundtrack on the camera also makes me t

Without going to Attopilot and making custom cables is this a sound way to keep using my Pixhawk power module. I'm consistently going beyond the 60A max sensing. Could this be a solution ?

Auto Tune on Large Octo
Auto tune worked great, much better than I expected. The only side effect is the difference in stick movements afterwards between stab mode and loiter/position
Otherwise pretty much perfect

APM2.5 V3 no longer flying Octocopters
I'm led to believe that V3.01 on an APM2.5 cannot fly octocopters in anything other than Stabalise/Alt Hold modes due to overload on the processor bringing the 50Hz loop down to around 5Hz.
1. Is this true ?
2. If so why is the firmware code still avai

Help Altitude Config
Just swapped my APM2 for an APM2.5 - all reload and fine apart from the Altitude. I've re-loaded firmware several times and re-loaded config, Even re-done config from scratch but I still get this...
My Apm2.0 reports 73cm and that is accurate why does

I'm still looking into how this happened today but just as a warning to anyone using motor leds there is a possibility of the LEDS flashing (Indicating DISARM) but the ARDU is in fact ARMED !Today I armed the Ardu and the lights went solid as expecte

Having finished the camera Gimball I'm very happy with it apart from the control I've got over the servos from the APM2.0
The movements seem very coarse and slow. If I tilt the machine quickly the gimball lags behind but does go level. I've tried diff

I was setting up my voltage monitor and noticed that the voltage on the Ardu 2 was 4.64V.
When disconnected the ESC produces 4.96V - Is this voltage drop expected ?
My only concern in that there is 4.64 volts supplied to the RX where the specs say the

I want to get the pack voltage reported in the telemetry just for testing, I'm running 4S setup with the APM2,
I don't have the relatively new voltage/current monitor, to use it I'd have to do a lot of stripping to get to the power system, but I'd lik

It's come to my attention tonight that the APM2 has a 500mah fuse. I was planning to run Servos for the gimball directly from the APM but at stall they would pull 4A and obviously blow the fuse.
What is the best way to power Gimball servos ?

There's been a few threads on LED strips and lights on the ARDU but most seem outdated now,
What is currently available at V2.8/2.8.1 out of the box (as it were) are any of the analogue pins already assigned with LED outputs ?
