"Are you using APM 2.5? if so, have you covered the baro sensor from light and wind? Just plucking at straws now...."

"Resolder all connections from battery to esc's. it's a pain but eliminate what could be originally lead free solder dry joints. A little resistance of old solder can be a heat/ current issue. I had issues with bad bullit connectors in the…"

"This might be a silly question but If volts / amps drop then what's the condition of your batteries? I had mine drop out if the sky due to a sharp voltage drop towards the end of flight."

"What's it like without sonar enabled? You could have a noisy rf environment where it is located."

"Hi Mick, Yes, I got the same. My solution was to open up google earth first. Then Mission Planner. Not sure if this does anything or not. It just worked after i do it. If  knew I wont have wifi or 3G on my iphone where I fly, I prefetch the…"

"Hi John, Did you do a radio calibration? I fall that trick all the time :)"

"Very likely. Maybe.  When I say "I", I mean we. Last position was in loiter before I selected auto in the MP. Normally my pilot leaves the throttle in mid position, which was pushed to max when the motors cut the first time. Does not…"

"I had the same thing happen after a day of really good flying of way points. However after it stabilised, I went back to land mode in the MP and the motors cut out again when it was at 15-20 meters, just like a disarm in flight. Really would be good…"

"Hi Vince, I have 3 similar incedences like that. Found that I had set up my bec and 3dr power module were fighting each other as they were on the same line. Also what broke the camels back was I had one Savox digital servo on my camera tilt mount…"

"This looks like the same message that my brand new APM 2.5 also hanged and would not progress. I found that it would connect using the CLI and tried the "test" function of the INS and it did not initiate. Give the CLI terminal a try and…"

" Hi  Xerravon,   I had this issue and similar issues when I failed to calibrate ESC's properly. If memory serves me right, I resolved this  by firstly setting up each esc (with a program card, pc software or…"

"OK, Tried the something similar yesterday. Not an expected outcome. The unit was decending  at its last  (second last) waypoint as expected (land command on 5th wpt) after 4 waypoints and auto take off. Pressed restart mission about 10…"

"Bravo! Nice demo. If you dont mind me asking,  how did you configure for octoquad (APM planner does not have the icon)? Cheers, Choppy"

"Hmm, nasty. Feel for you. Was a new battery put in, that is the unit rebooted? Maybe a re write of the flight plan on the mission planner might reset the plan? Or maybe trying the " Restart Mission" action button? I could be wrong but…"

"Hi CodyO, Does the light blue track on the mission planner stay stable around the copter on the ground before launch? I find that the Media Tech GPS is slow and not as good as the UBlox Lea6 version. It can show the gps tracking around my general…"

"Second that. Has it been released or is it just me that cant seem to get the motors to behave properly in octo quad config?"
