1st Tail Blades CFRP 105mm CP

I've had my Piuma for the 3rd season, and have run a variety of tail blades when I was experimenting with target rotor speeds. The Piuma has a tendency for tail resonance if all the right variables aren't in favor, and in my personal experience, it isn't very tolerant of the stock blades or Rotor Tech like I've used in all other models. I settled on Spin 105's and they are superb. I noted the shape of these as similar to the Spin 105's so I ordered a set with the new 700A mains. They have turned out to be veyr good. I on;ly have a few flights on them, but they run smooth, quiet, and do not aggrivate the Piuma's tail resonannce. This is with running the smaller tail pulley for max authority at lower headspeed on 8S of around 1300-1600 rpm. I know this is unusually slow, but it's where this model shines for me. These tail blades finally provided another great option, far superior to the stock SAB 105's.
