Century Helicopter has released some really nice high quality rotor heads that will appeal to scale flyers. Read more and see these new rotor heads and parts via the source link. http://www.centuryheli.com/newitems/index.html
Only see heads for the 600 and up or did I just miss something ? Expensive but for the larger heli's by "whomever" the prices would be prohibitively high anyway for this guys wallet
I don't have a 600 size either (yet), but those are some really nice heads for folks who might. You're right about the price, some cost as much as a whole 600 size helicopter kit.
