6 Motor Cut-off?

[Airtography]

A friend was flying next to a house and went too close. 1 prop hit the house and ALL motors stopped. Dropped like a brick. Question -- why did all motors stop when only 1 hit the house? Would think that the 1 motor would stop, but the others would keep running. Only 1 prop -- the one that touched the house - broke. Has anyone experienced this or can explain?

When it hit do you think that the battery could have been dislodged?

I asked him that and he swears that the unit was still powered on when it hit the ground. He tested all motors after the crash and they all work. (has a broken camera, 3 arm clips and broken landing gear stabilizer - legs were up when crashing and the camera took most of the hit).

If they have it set up to sense a crash and shut off all six. This would be a safety thing for instance if it hit a person o e prop then it only shut off one motor then the other 5 props would follow hitting the person.
Not saying I disagree with you. Just thinking along a different line.
