RE: I have a killer question......
HAH! Last weekend a friend was in town with his 400 - I had a few beers so didn't fly mine but he was feeling up to it. At the time he had wooden dowels for training gear and no balls on the end - you can guess what happened next.
The dowels dug into the concrete and the bird promptly flipped - the result was a shower of spinters that a beaver would have been proud of. When the grips stopped spinning all that was left was about an inch of jagged wood beyond the grips.
I've never seen this before but it was a sight to see.... it looked like someone just tossed a bunch of mulch into the air! I know it's not funny, but I just keep on laughing!
BTW it was the Align 325's that he shredded. Or is it 315? The white and red ones.
