Just back in from trying the second flight with this P3P. I took a friend out to the football field at a school just outside town, to show him how simple it was to handle basic flight. After going down my checklist, doing calibration and making sure everything checked out. I decided to show him how simple it was to just use Auto-Takeoff to get to a hover. I slide the button on the iPad, "the home point has been updated, take-off", the P3P immediately goes to full power and promptly flips over on the ground. Absolutely zero control from the App. I hand off the TX to my buddy, grab the P3P by the landing gear and finally get to the battery to pull it out. Press/quick release/press and hold does not shut the bird down. Fortunately, the only apparent damage is to props. This system was updated to 1.26 on 6/16/2015. It flew on 6/18/2015 with no problems. It's been in its case since then, until I took it out this morning to charge the TX and one of the batteries. Nothing else was changed. Now the App says NO MC DATA ACCELEROMETER FAILED. Told me to shut the drone off and restart. Did that several times. Told me to check connections on the gimbal. Checked them. Removed the gimbal to unplug and plug it back in - all to no avail. Tried to do the update on the bird again and it failed, saving it already had that version of the firmware. Unfortunately, it looks like I'm one of those with firmware issues. There's simply no other explanation at this point. Very disappointed at this point. Knowing what DJI "Support" is like makes it no better.
