"Hi. I do not use Mission Planner, (works poorly on Linux due to .NET lock-in)  , Using APM Planner, but if you can make it set an unsupported mode using simple GUI, (like a droplist)- that's a nasty bug.  - you should report it…"

Andre K. replied to Petras Litvinas's discussion Battery failsafe failure?
"yes, voltage is a better indicator, less precise prediction when you are 50% into the flight time,  but more accurate prediction of the end, like "5minutes left." it also handles half-charged batteries, and different capacities better…"

Andre K. replied to Petras Litvinas's discussion Battery failsafe failure?
"BTW: be sure to remember that you cannot discharge a Li-xx battery to 0% while flying. Whatever your battery capacity is , you should not enter more than ~80% of that."

Andre K. replied to Petras Litvinas's discussion Battery failsafe failure?
"Your BATT_CAPACITY  is 3670mAh. your FS_BATT_MAH is 3600 So you are asking for FS when there is less than 3600mAh left. your CURR.CurrTot indicates that you've used 70mAh right before RTL. So.. everything is fine. (which is pretty usual…"

Andre K. replied to Nayden's discussion pixhawk 3.2 firmware release date?
"The beauty of open source, is that it will be released when developers agree it's done, good enough, tested, and works. This is not proprietary stuff that needs to be selling on a specific date, however incomplete or defective. You are free to…"

Andre K. replied to Philip Johansson's discussion Obvious compass problem? Crash in Auto
"1: try droidplanner too, suggest for both authors to add this feature (not sure if droidplanner is still missing it) - APM planner can do that to, (in case you have a laptop with something else than windows) 2: hard to say if it did, without logs /…"

Andre K. replied to Philip Johansson's discussion Obvious compass problem? Crash in Auto

Andre K. replied to Staq Koenig's discussion All motors stop suddenly with Pixhawk
"ok, I guess you still won't believe my conclusion, like before - but what you *actually* can see, it Chan3 drop proportionally to 4, because motor 3 is the opposite motor of 4. Like I told you, you lost lift on 4, so the opposite motor *must*…"

Andre K. replied to Dominik's discussion Pixhawk Crashlog 3.2 rc5: Anybody can help?
