Wow, went out to a nearby field, to let my Rappy run loose a bit.
'was a noob doing some hovering, with an experienced pilot helping him.
Had my back turned to them while fueling up, heard this bang like something hit hard, turned around just in time to see bits flying off.
The guy never threadlocked the screws holding the blade grips on the feather shaft, one of the blades missed them by about six feet.
Amazing thing, other than some slight damage to one blade, the heli is fine !
Oh, the inner bearings on both grips are gone, never to be found again.

I doubt it, the heli landed upright from about three feet up.
The blades would depart almost simultaneously from the head, shouldn't bend anything.
I didn't inspect the links too closely, no glasses:-(, but both short links were still on the head.
I'm just kinda wondering, what else was put together incorrectly?

If they didn't threadlock the blades, did they threadlock anything? I've seen/heard of that one before...

Mumbo, perhaps... Jumbo, perhaps not!

IMO..there is no reason to NOT locktite any screw that threads into metal on any helicopter! How much effort does it take to do that?
it takes all of a sec to do for "piece of mind" flying.

It only takes two things to fly -- airspeed and money

Never turn your back to a newb flying a helicopter! You can never be too careful, you only get one life. Threadlock is a neccesity on all metal-metal parts in a helio, way too many vibrations.
