We had this discussion at our field Saturday and it was explained per a conversation with henry caldwell, that tail blades should not be tight. maybe not completely floppy, but snug enough that if the tail was shook they would fall under their own weight.
***the reason---as to why is because if they are too tight they dont lead-lag very well, or better explained they wont lead lag properly. We were told that that its important that the tail blades be able to move in flight otherwise they'll stick and then be thrown as opposed to flowing properly.
Not saying I fully understand the physics of rotary flight but those that are interested this is what Henry was saying.
Main Blades---these need to be pretty snug. But if they are too snug they will cause a vibration that you'll see like the FBL unit is having a fit. Also this important when doing autos blades to loose will fold if the auto isnt executed properly or you run out the inertia to early. I cant say these examples have ever happened to me personally, but then again I run the blades tightness according to how I've listed here and have had zero problems.
Matt thoughts?
