Rich,
Yeah, I got one chance after the firmware update and I noticed two things (not enough testing for any conclusions yet). First, my GPS normally locks almost immediately with 8 or more Sats. On my little test flight it came up with 4 and took a few minutes to get to 8. Second, I took off with 8 Sats in GPS mode, got it up about 20' or so to let it hover, it was all over the place. Good 10-15' swath. Made me nervous enough that I put it in manual and landed it. Rebooted everything, went up again with 8 Sats, got to 13 pretty quickly but did seem to be, as you said "floatier". I didn't conclude anything from it because it was such a quick test and I wanted to wait for the new app anyway. Maybe a level and compass cal is in order with these updates. Just thought I'd throw it out there.
