I also updated one of my WKM. With good internet, I had to do it 3 times. I also notice the update beeps/pings was kind of random and not as uniformed sound as the other updates.
My Assistant seems to load now, re input all my numbers, did a write.. I did notice, when I looked at my TX control, there was a lag when I move my stick around. I recalibrated it anyway.. it was still lagging after the calibration. I wrote to the WKM, closed the assistant, and reopened it to see, seems like everything is there, except my lag when I move the stick around.
I flew it only in in GPS low flights.. 50ft-80ft.. did not do RTH yet. even though the WKM assistance shows a lag in response when I move my stick around, it still seems to fly well for the hover, short flights.
I do notice, that when I launch, the F550 seems to have a lag in bringing up one side.. this tends to feel like it is getting ready to flip while taking off, but if I power out, it lifts up and then hovers fine.
What gains should I mess with? is this in the autopilot section?
