Good information Shadow99. I am a firm believer in the knitting needle tail boom, but not that awful purple color. Thankfully there are more color choices.

There are some that prefer the carbon fiber tail boom. If you have a local archery shop you may be able to pick up some scrap cut or broken arrows. Just be sure they are 8mm.

The plastic blades are a real good investment also. I prefer the flat bottom, as I have no aspirations of doing any 3D yet. Still working on 1D.

Stock tail rotor blade sucks also, very brittle and breaks if you look at it wrong. Go with BladeCP tail rotor blade. It fits and the blade root is thicker. Also the BladeCP fly bar paddles work and have a bolt to hold them in place.
