ORIGINAL: wojtek
moral of the story is, something can always go wrong, no matter how we try to prevent it ... i had a power bus, and a batery redundancy system on top of that in my turbine bell230 (3 batteries plus ECU battery) .... it crashed anyway .... why ? because the tail rotor shft sheared
... at least my power system held up
