So look, I am running out of my 45 return exchange policy, and I THINK my bird is 100% it has about 35 miles under its belt and about 10 hrs (I'd have to look for exact because of the P3P I exchanged once already for this is incl. in total) but anyway, you guys get what I am saying, risk the bird you trust, over what I may get? And here is what it's about, the **** tilted horizon! I cannot believe this isn't a systematic device wide software development/implementation problem, but in fact it's my actual poor bird. So this is where the BS meets the pavement, if you've never had a horizon tilt problem, and still don't, with the new "accuracy to +- 0.03%" gimbal on the P4, then you should say return it tonight. If your like me and think all of them seem to have a problem related to the horizon on their machines too, then your like me and think that won't fix the problem. And please, please let's not insult our intelligence by stating obvious statements like "use the auto calibration" or "did you calibrate the IMU?" Because like me, the others having this problem have done it all, I actually calibrate the gimbal before every flight, on a flat level surface. (I have a spot I checked and like 90% of the time I use that anyway). One thing I will not do is chill my machine down before the IMU cal. If we have to do something so invasive and counter mainstream wear longentivity issues, I'll just sell it because that's ridiculous, IMO. I haven't heard to do that for this, just saying, don't lol.
