Assuming, say, a blade grip failed in flight and the rotorblade comes off at peak headspeed. There's a total, 360 degree potential area of exit for that blade. .
That's the thing that always scare me. I'm new to helicopters. What's the good way to prevent a scenario from happening? Check the blade bolt everytime flight? How about just solder the thing.
Make sure to locktite your spindle bolts and do a good preflight before the first flight of each day, checking linkages and looking for slop in the head. If the spindle bolts are coming loose you'll notice some play. It isn't always possible to catch everything but it's worth a look every time you go out to fly. An actual failure in the air is pretty rare, usually if anything happens, something will come loose and the heli won't fly right, but it's rare to actually see a part fly off the helicopter. When I fly I'm usually at least 30 feet away from me, flying 50 and 90 size helis.
