"Hi Guys I have the same issue as Simon. After upgrading my APM 1280 to a 2560 a few month ago, I have also noticed that the voltage sensing was not working as Simons says. I purchased an Attopilot voltage and current sensor and still the voltage was…"

"I am using the standard pre-compiled code (2.22) that I installed via Mission Planner. Was this code compiled with THROTTLE_FAILSAFE set to 0 or 1?"

"I am interested! where is the link?"

"Hello,   I have the same problem with configuration and reset or power reconnection...   Did somebody resolve  this issue?   Regards, Gregory"

"Chris after updating Mission Planner I was able to install the skywalker param.  I haven't flown it yet,  just tilting the aircraft to test stablise works.  I see the APM sends the right commands, however I'm concerned about…"

"in the newest planner this is now ignored, so should not be an issue"

"The skywalker config file has SYSID_SW_MREV 8 in it, but the current code wants to see 9. If it sees 8 != 9 then it prints "EEPROM format version %d not compatible with this firmware (requires %d)" and erases all the parameters."

"So 3.2 or something like is ok fr skywalker? The default is only like 0.8"

"Yes, the Skywalker P values should be higher, as shown in that config file. The default PID values are all very conservative, and are meant to fly any aircraft okay. On most aircraft you would tend to raise them as you tune for optimal performance."

"I had the same problem after loading the skywalker param file. I did notice that the stabilize P values on the skywalker param is a lot higher that default is that correct or a legacy value?"

"ive found the problem when restoring from a param file. if the file was saved under a diffrent version of apm, it reset on next reboot. i will be adding a check/ignore in the next planner version "SYSID_SW_MREV" is the issue"

"Hi Simon   This is the third thread about the same issue in three days. My thread. Reset button (clears waypoints) Lets work together to see what could be causing this problem. I also identified one possible cause with uploading the Skywalker…"

"Seems to only happen when I upload a file."

"thanks for the quick reply.   Just erased it and quickly configured a few setting and rebooted it. Worked fine. Everything looks good.   Then I uploaded the attached file and the same problem happened. I did the same thing with the…"

"try doing an erase from the cli, and re setup."

"Also if I upload the SkyWalker pram file from google code the altitude is about 1500m out.   Seems weird"
