Sorry mate you are are so so wrong, come over here to the UK and I will show you how a friend does it by painting the blades on a set of scales to make sure they weigh the same. The proof mate is in the pudding. I will guarantee you that balance the head ( in this case a 500 ) with a chadwick with no blades on. Put the blades on having painted them on the scales so they all weigh the same and guess what the balance doesn't even show up on the Chadwick, don't need to add any weights or **** up the dampers by sweeping the blades. Done it on 206 blades, Enstrom blades etc etc. Have sorted blades out that have come back from the so called blade overhaul shops with blades in some cases weighing 250 g and allegedely have been statically balanced. Put them on the aircraft and do they fly like f... Give them to a maintenance company and they will add weight to the head or sweep the blades to try and balance when the fundamental problem is the blades don't weigh the same !!!! The answer really is that simple
