1.6.0040 is out. See this thread
Phantom 3 Professional Firmware v1.6.0040 | DJI Phantom Forum
There I'm glad it finally came out. Of course I couldn't talk about it until it does come out. This firmware will take care of the battery issue we have seen a number of crashes over. So you DO want to take this update seriously and get it installed!
We actually were able to even test this update in some cold conditions. The coldest for me was only in the upper 20's, but there were others that flew in colder climates.
Since updating the firmware it seems to me like my flights have extended. Example, on the upper 20 degree flight I flew just over 14 minutes and had over 50% remaining. That is pretty good considering the cold temps.
Btw, you will want to update each battery you own. Just leave the microSD card installed You can do this by switching out each battery after you update the firmware. Just power down the a/c, switch battery, and power up again. The process will be very similar to the firmware update. The batter update should only be around 8-10 mins.
The 32 channel mod still works for android. However, it seems like the ios beta team was unable. I have not tried it on my mini 2 tablet to see if it does or not. I thought it didn't work on my K1 Shield at 1st but once I rebooted the K1 it worked no problem.
Let me know if anyone needs help.
