Thank's guys that's the video that I was looking for. N017RW -That's a great tip.

Hi. I'm sure this is somewhere in the forum but I can't find it... Can anyone tell me what the compass raw values should be (or the lower and upper ranges for x y z and mod? It used to be available on a you tube video but it has been deleted. Thanks for your help WW

Someone cynical might suggest that increasing the time until auto land increases the chance of a bad battery going unnoticed within the 3 month warranty period.This could save DJI an awful lot of money on warranty claims. This is the only logical reason to do this. This seems to be good news...

If it's a case of being nervous about flying it, there's not a lot to it. You'll find all you need to know on You Tube. There's advice on your first few flights, calibrating your compass, GPS and what the light patterns mean, take off and landing, and setting up your Phantom in the Naza...

It is still only accurate assuming a standard lapse rate of 2 deg c per 1000ft though. I agree it's near enough for hobbyists but the op was asking why his altitude reading wasn't always accurate.

Because a barometric altimeter senses pressure and pressure varies depending on ambient conditions, not just with altitude and the phantom has no indication of the altitude it is starting off from. This is why I asked whether it indicates above MSL or AGL, if it's AGL then yes, it only needs to...

I think for anyone to be able to answer that with any degree of certainty they'd need to know how a Phantom behaves when the battery is close to and at exhaustion. Do the motors just stop working abruptly or do they just get increasingly slower? And once the motors have stopped does the phantom...

Surely it would need to know either the current elevation or the barometric pressure in order to do this.

This raises the question for me at least - what altitude is the Phantom reporting - Above Mean Sea Level or Above Ground Level and is the barometric pressure gauge only correct at 29.92 hg? Without adjusting the barometric pressure gauge to the current local pressure setting or without...

With the new update, it is reported that the firmware voltage threshold for autoland has been lowered - however with lipos the rate at which the voltage drops increases as the voltage decreases so once autoland presents itself there is less time for the aircraft to descend safely. Couple that...

My main findings regarding 3.08 was that, Autoland kicks in at around 20% where previously it kicked in at 15%. (This may just be the start of early autoland problems though). I was unable to override it with control inputs (something that I thought you were supposed to be able to do). However...

I wouldn't rely on dji batteries either! The early auto land can kick in with plenty of charge still in the batteries, it may not drop like a stone (although allegedly that can still happen due to the new update) but if you are over trees or water you're still screwed. I won't be buying dji...

I'm sorry to say this is very common - lots of people have been reporting this sort of thing - there is a very long thread dedicated to this on the non vision forum. Non vision owners have been experiencing early autoland despite the battery percentage being reported as well in excess of 15%...

Has anyone else tried this yet and got airborne?

I haven't been following this thread recently so forgive me if anything I;m about to write is incorrect. Early this summer I experienced a premature autoland and noticed like some people that there was a significant imbalance in the cell voltages. I fully discharged my batteries and recharged...
