I went through several phantoms, and now have 3 different drones (including P3Pro), but I still try to use my Phantom 2 with gopro camera.
I consider myself rather advanced pilot by now, and I was able to solve several problems with my drones. But now I am puzzled.
some 2 weeks ago, in middle of flight on a calm day, drone started to act up. I could not pull it down, kept going up. then when eventually it reacted to my remote and started to go down, it went sideways and i had hard time to correct its flight. I eventually brought it down ok.
I checked for all firmware upgrades, did advanced calibration, compass calibration, remote calibration, everything possible I did, just to make sure all is ok. I reset to factory settings. And I tried to fly again. All LED light codes are ok, and i see on my FPV screen that GPS works, satellites are ok. Lights blink properly, showing constant contact with remote control, no alarms, nothing. So, i tested again, and when I tried to take off - It went up like a rocket, immediately up on high speed, some 15 meters or so, while I only tried with remote to bring it slowly up above my head. It again took several seconds until it decided to descend - and then it started to go down like crazy, I had to pull up the throttle to the max, and in last second before crashing it went up - again like a maniac. Then it started to go left and right on its own - like drunk (still showing on telemetry reading all satellites OK and no alarms, with all lights blinking properly. I had really hard time avoiding a crash, as it went just crazy, drunk, berserk. After a minute of trying i managed to bring it down to a reasonable level and grab it (I had to duck down as it went to hit my head, ha ha). Then, when I was holding it, motors still were going crazy - like NEVER before. just from almost 0 to full blast and all in between, nothing similar to usual behaviour when you catch your drone.
i re-calibrated every possible thing, paired with with a spare old remote to see if maybe remote was at fault - no change. Still crazy. when on ground, all is normal, motors go evenly, it reacts to remote. the circus starts when it lifts up.
I did not have any crashes or hard landings which would affect anything inside. All controls show proper operation, but it goes mad on every flight. It is not a reliable tool, and now i am afraid to use it at all.
any suggestions?
This forum helped me before, and I hope some of you may know what is going on. Would be a pity to trash it. but i don't know what to fix.
Many thanks!
Derek
