After crash I've rebuilt my F450 that was flying perfect to F550 in quite heavy version (AUW 3150g). After upgrading it to 5.06 had strange problems that caused two crashes (it was fliping right). I've alse replaced 6th motor and ESC because I didn't new if the problem was because of WK-M or because of ESC. Bu even before crashes my hexa had strange tendency to drift in random direction (ca 1-2 m/s). Now after upgrade to 5.12 everything seems to be perfect except drift and may be some white flashes. My IMY is firmly atached to lower plate with thin, strong double side tape (not foamy one). My radio is precisely calibrated.
Today I've associated basic gains (roll and pitch) with a knob on my transmitter so I can change it from 100 to ca 350. Raising it didn't help. I've also noticed, that in Att and GS mode to maintain constant altitude I need to set throttle to ca 60%, not 50%.
I've also noticed that the drift tendency is much stronger in GPS mode then in Att mode.
When I release sticks on my radio my exa should stop, but it doesn't - it continues to fly in direction it was flying before I released the sticks.
I don't think it's a problem with firmware because it was drifting with 5.02, 5.06 and 5.12.
Any ideas?
