- Where do I add weight to a main blade
when balancing them ?
thing I suspect I need to do is explain what you need to do to
balance your main blades, but I have already done that HERE........
Once you have
found the COG (Centre of Gravity) and made sure that both blades
have exactly the same point, you have to balance each blade against
the other one of the pair. You do this using a blade balancer, or
you can use a bolt through the mounting holes sitting on top of
something suitable so that the blades can hang down and move
freely. Once you discover that they do NOT balance, you
obviously have to add more weight to the LIGHTER blade.
Well, a lot of
people assume that you add it to the outside end, where you have the
tracking tape already, but that is WRONG...
If you were to
do that, you would of course change the COG on that blade, which you
definitely do not want to do. So you place any additional
balancing tape (electrical tape usually) around the centre of the
lighter blade, exactly over the mark you have made for the
COG. That way the COG remains correct, and you can add as much
weight as you like at the COG of the lighter blade.
THIS EXPLANATION HELPS ... ?
