vorweg: Das ist mein erster Beitrag und ich werde erst in kurzer Zeit stolzer Phantom Besitzer sein, da sich meiner noch auf dem Lieferweg befindet. Nun habe ich zum einen in Athurs Channel gesehen, dass es bei der 4.0 Version Probleme mit den Entfernungslimits gibt und der Quadrocopter unter Umständen nicht mehr zurück kommt. Noch beängstigender finde ich jedoch diesen Beitrag aus der Facebookgruppe "DJI Phantom Owners Page":
4.0 Updated = Fly away. Prelude then story, if you don't want to read the whole thing, the important stuff is 3 paragraphs down or look for "START HERE"! Thank you!
Now before I blame it on 4.0, I'll give you some history. I've owned the Phantom since 3.12 firmware. I've ALWAYS re-calibrated the compass every time I came to a new location even it's 5 miles away. I ALWAYS took off in GPS and ALWAYS waited for all solid green blinking lights. After the battery was plugged in, re-calibrated, and gopro turned on. I'd say it was about 40 seconds to 1 minute prior to taking off. Once I take off, I let it hover to ensure stability and GPS lock, check for all green lights again, and then go about my flight.
My equipment with 3.12-3.16 was an ARRIS gimbal, go pro, and 600 MW immersion transmitter and fatshark goggles. I NEVER had a flyaway and return home always worked (I just used this to test it, but always had eyes on the DJI). I also tried IOC and that worked flawlessly.
START HERE - As of last week, I found out about the 4.0 update. Before I updated, it was always the goal to purchase the zenuse, but I didn't want to have to instal the upgrade kit and go through the hassle. After biting the bullet, I purchased the zenmuse and upgrade kit (Also a screen and receiver to eliminate the goggles). Installed everything saturday morning and updated to 4.0. I re-calibrat, recheck ALL parameters (I took screenshots of where my previous settings were) and went to a park and plugged in the battery. Everything looked great! Green lights, reset compass, all motors went into idle, powered down, etc. (I've worked with soldering, building PCs, etc. So I guess I still have my skills!) So as I confirm all LED blinks are green, go pro is on streaming to my ready made RC screen, I took off. Video quality looks great, fly for 5 minutes and land. Looks good. I pack up and go home. I tested everything for an event I was going to the next day, Sunday.
Sunday comes along, I unpack, hook everything up, power the screen, go pro, transmitter, then the DJI. LED indicator red, green, green, red, blah blah blah.. Up, down, up, down, up, down, etc LED = Orange. I do the 360, then face down, 360 again, blah blah blah.. Set it down.. Confirm video is recording, streaming live. Wait... wait.. wait. ALL GREEN!! Confirm.. Okay just making sure, all green! TAKE OFF!! Set it up, Position the DJI! See clear video. I'm at about 80 feet. Filming what I'm supposed to for maybe 5-6 minutes and about to call it quits. Here is where it all went wrong. I pulled down the the left joystick to lower it down and it just stayed put. So I press forward on the right stick to come closer to me (I saw myself in the screen to move towards me, but nothing.) Only control I had was yaw. I could pan left and right and even 360 degrees, but I couldn't move up or down or back, forward, left, or right. That's when I knew something was wrong. Then not 30 seconds later it started drifting away from me. (I live in San Diego, so yes right near the ocean) I yaw left to the direction it was going and I see it going towards the ocean... I yawed 180 degrees again, I see where I am flying and my car which is parked... I press forward to come towards me, and it's still going away... I set home lock and pull back on the stick.. Still nothing. I set my bottom atti to fail safe, and flip it there yet the FPV still shows it going away.. I then flip the atti to gps up and down between GPS and middle atti to gain control and pull down the the throttle, but there is no communication with the DJI except FPV and yaw. At this time, it's holding altitude and appears to be drifting with the wind only which was going towards the ocean. Seems like any right stick input was useless and only yaw worked on the left stick. FPV confirms that the battery was going low and slowly went 1/2 mile away into the ocean.
Thanks for reading thus far! Now, I typed this in as much detail as possible to eliminate any user error and to show I've much experience with flying the phantom. I've even thought to myself that these fly aways are user error or impatience with waiting for the IMU to warm up, etc. Having experienced it 1st hand, I can honestly this was a problem with the phantom and nothing else. What are you thoughts or input?
It's much appreciated.
Kurz zusammengefasst, ist dem armen Typen sein Phantom inkl. GoPro und FPV aufs Meer herausgeflogen und wurde nicht mehr wieder gehen.
Nun bin ich echt unsicher was ich genau machen soll wenn der Phantom hier bei mir ankommt. Soll ich auf 4.0 Updaten? Soll ich die Standardversion beibehalten?
Und habt ihr vielleicht schon ähnliche Erfahrungen gesammelt?
Viele freundliche Grüße,
