It looks like this may be a discontinued product already. My Tower Hobbies sale flyer just advertised the RTF and RxR at lower prices "while supplies last". It looks like mine may end up being a FrankenAxe if I keep it flying. The CNC parts never did come out for it, and I really would like to upgrade it eventually. Looks like the eFlight Blade 400 head and tail parts may be an exact fit. On a further note, I have a cat that chewed the tip of one of my main rotor blades a while back. I replaced them with the Align 325 Pro woodies and like these much better.
I highly suggest the 325mm carbon fiber blades. They made my Axe 400 dead silent and the flight characteristics are incredible now, much more stable and agile (not to mention the blades look great!)
I put the 62mm tail carbon fiber blade on also, very nice!
