Of your story maybe, I've successfully flown the aircraft for around 200 hours, fixing most thing as I go along, then the occasional full maintenance hangar reset.
The most common cause of `not random` failures are:
1: Idiot owners who don't know how to fly the aircrfat without breaking it
or
2: Idiot owners who don't have their sim setup precisely as recommended by A2A in their extensive manual.
Then there are a statistically small number of idiot owners who didn't install it correctly, as Bill says.
Spot the common cause?
