Well the manually actually contradicts itself, as in one spot it says to calibrate in any new location and then further on it says to do it each and every time. It's no wonder customers are confused.
In my experience to date, taking off in a 'clean' metal free location is more of a concern. I've experienced the toilet bowl effect and a mini fly away so I'll always check the MOD values before take off now. I'm never really confident until I've flown for a minute or two. Other's have not had any such hiccups.
Learn how to quickly switch to and fly ATTI mode and you will likely be able to combat issues that arise with the IMU/compass sensors.
Yes, Ive only been flying a few months now and Ive had to nearly close calls. Only one out of the two did I actually crash.
There's this local park I go to fly... the first time I ever flew there everything seemed perfect .. went back 2-3 times and all went smooth. 2 months later I return and I noticed that the drone would be very unstable (P2 Vision+). The last time I flew it there (2 weeks ago) I was in the air about 60 ft and the drone started drifting to the left and rotating somewhat IIRC. I was able to regain control still in GPS mode but never understood why all of a sudden the same park, same spot I was experiencing such instability when I finally started getting comfortable flying there. In fact, I don't think I ever put my P2 into Naza-mode?
I would ALWAYS do a Compass calibration pre flight. Something I did notice was that although I had 8-9 satellites, it would switch rapidly from Safe to fly to non-gps or something like that as if the signal was poor or something and this started happening after my 4th flight or so. At this point I just avoid going there.
The second experience was when I had just landed in NY on a trip back from FL. I arrived home, got settled in, took the drone outside, did a compass calibration and took off.. 20 seconds later it felt as if it was ATTI mode and I was losing control. I hit the ground as it looked like it was going to take off by itself or something. The camera was misaligned and I broke a prop guard. This time, I think this was caused by me no doing an IMU calibration.
Another concern of mine is, I see people talk about a lot are power lines etc. I live in the City where we have over head residential power lines and haven't noticed any real problems flight wise. What are your thoughts on this btw?
Appreciate your help! I feel safer already
