Gimbal reverse 'bounce'

[Phantomrain.org]

There are some videos of the Mini 2 chasing trains and although the gimbal does move some its not as bad as what you have been describing , you might want to consider returning that one.

We make a habit of always purchasing Two of everything to make sure we get something perfect out of the box and sometimes have to choose which one is better. , I suggest you consider that on your next purchase .

...If I understand you correctly though for part 3 with the pitch of gimbal moving up and then staying there by design then when I came to a stop the camera would be pointed up in to the sky and that's the opposite of what mine is doing

Think you are mixing all you say between relative AC & relative horizon ... in my part 3 scenario the gimbal will be forced down by the AC to a position 20 degrees below the horizon ... once the gimbal have been pushed down it will stay at that position relative horizon even if the AC levels out when you stop & start to hover ... the gimbal will NOT return to the original position leveled with the horizon ... or if you will 0 degrees relative the AC... & horizon.

So all is as you describe your Mini 2 behave ...

...I took the lil' bugger and the MA2 out a few minutes ago to do some various non scientific test runs... In Normal or Cine mode there is zero problem no matter how hard I throw the throttle up or whip it around in flight.

All as expected for the MA2 ... that AC have a headroom of 4 degrees at maximum AC pitch in those modes before the gimbal hits the mechanical stop.

...When I flipped to Sport if I REALLY slowly added throttle like someone earlier suggested I'm good until about 22mph and then the gimbal moves approximately -5° relative to the pitch angle of the aircraft in a sudden jerking( bounce as I originally called it) motion. At about 25mph in the same slow ramp up of throttle it moves another -5° on average. Continuing on to about 30mph it moves another negative 5°.

That behavior is the same for my MA1 ... seems completely normal. You nudge the gimbal, it reacts with creating a distance to the AC ... you nudge it some more again as the AC pitch increases & the gimbal backs down again.

... if I was to stop the flight the camera will remain pointed downward relative to the drone and horizon until I use the wheel.

Again ... this is how DJI have decided it should be ... if the gimbal have been nudged down by a to large AC pitch it will stay at that angle relative horizon even if the AC levels out again.

...When in sports mode the MA2 tries as hard as possible to maintain or reach 0° relative to the horizon up to the its max allowed movement, it never points the camera farther down.

If you start doing the math from that the AC is leveled with the gimbal pointing straight forward ... you will see that when the AC have reached 24 degrees pitch nose down the gimbal no more can keep it's direction pointing straight forward ... it's now relative the AC pitched 24 degrees up which is max.

If you from there continue command the MA2 for more speed it will continue to pitch down to max 35 degrees relative the horizon & by that push the gimbal down 11 degrees below the horizon.

Doing the same math for the Mini2 will render the gimbal pushed down by 20 degrees instead ... so the difference between the MA2 & the Mini2 isn't minor ... the problem for the Mini2 is nearly twice as severe degree wise & compered to the Mini1 & MA2 the difference is shockingly large viewing the live feed on the screen.
