Plz help with an autopilot crash.

So my custom built hexacopter crashed during an autopilot flight. This was after two successful autopilot missions on the same day. Everything seemed to be working fine. I am running a pixhawk with 3.3? firmware I think (I updated it about 2 weeks ag

What is PM Test in DataFlash Auto Analysis?

Question about CAM_DURATION Parameter

I have a PWM switch hooked up to AUXOUT 1. It is activated like a camera servo from CH8. But because of the CAM_DURATION parameter, I can only keep the PWM switch on for a maximum of 5 seconds. Is there a way to keep the PWM signal high with the came

Dual GPS question

I am thinking of adding a second GPS unit to my Pixhawk powered hexacopter.

Do I need to run through the hardware configuration again, or just modify the parameters as described here?  http://copter.ardupilot.com/wiki/common-optional-hardware/common-p

Can I add custom camera profiles to Tower?

I usually fly survey missions using Tower on a Nexus 7 tablet but I always have to change the altitude and sidelap settings to get the flight that I want. Is there a way to make a custom camera profile and add it to the drop down menu in Tower?

Pixhawk total power failure in flight

I was flying my custom hexacopter with Pixhawk running Arducopter 3.2. This was my first flight after a previous crash took out a few speed controllers (I made repairs, updated firmware, and ran through the initial setup again). At first the hex flew

Low board voltage issue

My custom hexacopter is flying just fine. I am running a pixhawk with 3.1.5. However, when I run the auto analysis of the datalog, I get a VCC warning (see pic). When check the "Power Issues" graph (see pic), the board voltage is between 825 mA and 1

Need help with altitude sensors

Power Distribution Board Failure

I have the 3DR hexacopter PDB. Recently my hex went down when one of my motors stopped in flight. I thought it was a failure of the ESC. Turns out, the PDB must have shorted out because I am not getting any voltage to that ESC. Power to the other ESC

How do I connect LEA6 to u-Center?

Optical sensor corrupting eeprom

Not sure why, but I discovered that the optical sensor was wiping out my eeprom every time I powered up my APM 2.6.  I had to erase my eeprom and reprogram the APM every time it happened.  I'm just going to remove it rather than troubleshoot it as th

Battery spark wiping out EEPROM?

Seems I am corrupting the eeprom on my APM 2.6 almost every time I connect my batteries.  I am using 6S 10Ah packs with XT60 connectors.  Every time I connect them, I get a large spark.  I am guessing this is what is corrupting the eeprom.  Should I

APM 2.6 ABC LEDs don't light, Can't connect to APM.

Hot motor problem

One of my motors is getting extremely hot.  I was checking the motor direction after calibrating the ESC's and I noticed one of the motors got too hot to touch.  All of the others were ok.  It only does it when the motor is moving.  I tested the temp

Calibration problem?

I am trying to calibrate my radio in APMSetup.  I move the sitck and the red bars move.  I go through the calibration and everything seems ok.  But when I go back to the radio input screen, the green bars don't move the full range on screen and are n

How to change PWM values?

How do I change PWM values in MP?  When I calibrate my radio, the lows seem a little high (>1200).  Because of that I can't get to mode 1 with the F Mode switch and I think it might also be the reason I am having trouble arming the motors.  TIA, Greg

XBEE for FPV?

If I add the XBEE telemetry unit to my ArduCopter, can that be used for video transmission or do I need a separate TX/RX unit?  -Greg
