Mini 4 Pro Unstable on the pitch axis

[Travel_Mate]

It's a bit premature to declare this happens with every Mini4P. I've tried several ways to make this happen. Take a look at
Mini 4 Pro Unstable on the pitch axis

Keep calm, it happens to every mini 4P... You simply haven't noticed it, when the drone is away or high, it's hard to replicate, happens randomly, when OA is off, chances are little less, but it happens, even happens to repaired and replaced units. No worries, it's just little scary, the drone keeps flying. Many people do not notice it, till special conditions are met

I'm not sure what you mean by "notice it". I look at the log files to see if this happens. It's very distinctive and easily seen. The pitch oscillations swing 45°. Take a look at posts #12 and #39.

I look at the log file for almost every flight I do with my Mini4P. Several of these flights replicated the conditions described by others seeing these oscillations. If this happens with every Mini4P I would have seen it in the log files by now.

hi. have a look on this.

Note 1. I’m using motion controller 2 and goggles 2
Note 2. Pay attention only when flying in a straight line. I did lots of short passage to be on LOS.

Looks like there are several instances of the oscillating pitch problem. E.g.,

Yes. I figured out how to reproduce the problem whenever I want with the motion controller 2 - just flying strait and swinging the motion controller up and down a bit fast (keeping the throttle squeezed).

I tried this and found something interesting. Twice in the flight swinging the MC up and down did cause the Mini4P to pitch oscillate. But for only a few cycles.

In my case it happens on every single flight using motion controller 2 and goggles 2. It is very annoying and turns out that the battery life decreases a lot due the oscillation. I will return my drone to dji care center to see what can be done. What is weird is that with the RC2 I could not see the same issue and it seams to fly well.


Note: I used a friend’s motion controller 2 and the result also remains the same

I was out with my replaced by service M4P today and feeled the pumping again. On the first flight when I got the replacement drone I thought it is better than my original drone, but now I think it's just a little nuance better.
DJI should really address this by firmware.
