Just loaded it up on my testbed WKM quad and did a 5 minute test flight. This is the release that is supposed to make large frame multis more stable, the quad doesn't quite qualify although it's 600mm it weighs in at 2750 grams so not really a heavyweight either.
I did notice the transition from ATTI to GPS is perfectly seamless I had to check the LED to make sure it had actually changed,so definitely a plus if you switch modes while doing APV work. I have the ATTI gains on a slider with midpoint at 80% and adjustable from a low of 55% up to a maximum of 125%. Previously the quad had rock solid GPS position hold at the 80% setting and that includes in gusty wind. Today of course it's a bit drizzly and dead calm so I can't judge if there's any improvement in windy conditions but I did notice that the position hold wants to drift at the 80% ATTI gain settting where it was pretty locked in before, pushing the ATTI gain up to 125% seemed to lock the positon hold in like it used to be at 80% which would indicate that something has changed in the GPS code.
According to the release notes the differences are...
Optimize the GPS Controlmode; improve the control performance
and for new features,
Five level motor idle speed adjustable in motor mixer
So in the short and somewhat limited test flight I did see some difference in GPS, haven't looked at the motor speed adjustment yet as the quad seems to be just fine with the Avroto motors and reflashed ESCs. Idle speed is a bit more of an issue on my Cinestar with AXI motors but the firmware won't get loaded there until I've had more opportunity to bang the quad around and I feel comfortable that there aren't any bad things that might happen on the big hex. Ultimately that will be the real test, to load it on the Cinestar and see if it makes ANY difference when flying in windy conditons mainly because that's where the major problem is. While better position hold would be nice if the frame is still bouncing and jumping all over the place in ATTI mode with wind then it's no better off than with the old firmware.
More as I get time to test, hopefully it won't be wet tomorrow and I can get a couple batteries through the quad with the new firmware.
