I'm guessing that since I don't have as much as a wrinkle in the skins and a few other XLs have way more flight time than my 45 hours, maybe, just maybe the plane is so responsive to elevator inputs at cruising speeds that some guys are using the joystick as a wing removal lever.
Some of the construction and assembly was difficult in one way or another on my plane but none of it was so tough that I'd expect many builders to muck it up. But then again there's no indication that many builders have mucked it up. Just seven tragic crashes. Could it be that the plane is not overbuilt enough to tolerate rough handling?
Something is definitely going on but there's no way to know what each of the crashed planes had been through before the crashes. Man I hate all this guesswork and speculation... mine as well as everyone else's.
I worked from your basic suggestions in designing the electrical system of my XL. The battery is isolated behind the master relay. The alternator / regulator output is isolated behind a 35 amp switchable breaker. The breakered output of the alt. goes through the ammeter shunt and the master relay output from the battery tie in together to power the system. I'm using an EXP BUS 2V to manage most of the power users. The flap motor required a haevier breaker than the EXP BUS provided so I added a 15 amp switchable breaker for that. Similarly, the gps power and the trim system required a lighter breaker than the EXP BUS provided so I added those. The power to the EXP BUS passes through a "main" switchable 35 amp breaker.
