idk, my phantom flies fantastic ( i have a p2v non-plus).  it may be possible for myself or others around here to help point out potential areas that might be causing your craft problems but we would likely need much more in the way of details to pick apart the problem.  

You will get the same feeling first time you take off a new plane

My Phantom almost never makes it to 15 minutes - at that point it may wobble as it tries to get back to earth or to home point or to somewhere.....

Sounds like a bad GPS lock - which is more possible at home yard due to possible interference. You should try in ATTI mode and see if that wobble goes away - but, of course, after 15 minutes it's a crap shoot. I'd say a 14 minute window is about what most can expect.

If you flew it out of sight already on the first dozen flights you will probably lose it before long. That's just a statement of fact. It's not made for that kind of use and, of course, here in the USA that's against FAA guidelines.

I'm not saying that to be critical of you...just that higher risk = higher chance of early loss.  This craft is designed as a flying camera and will only last if flown very conservatively. If you want to really fiddle, get a plain P1 or a discounted 350QX (as low as $300) and at least you won't feel as bad when it goes out of sight and doesn't come back.

Did you upgrade the firmware to 3.10? If you did, revert it back to 3.08 as DJI recommended . There is a problem with 3.10.

I don't know all the terminology u guys use but I'll do my best. Pv2+ flew like a dream for a dozen  ...

Any wind?
Did the wobble happen while descending or while in hover?
What's your current firmware version?

he said in his second post that he kept noticing 'a wobble while in hover'
