bdavison has not tried the E-Flite aluminum head because no one has. I believe he was talking about the difference between the E-Flite Bell/Hiller setup and the E-Sky one. Those pictures AJ posted were a little taste that Jason gave us a while back. Jason has not said any more about it.
E-Sky does not have an aluminum head for the cp2 either. The only one available now is the one heli-direct and heli-hobby sells.
I thought that was the bell/hiller, sorry. But the CP2 bell/hiller is what bdavison said was very good (and yes it is plastic). Which one is the one selling for $110? It is aluminum and has been out for a while now. And Esky does have a CNC aluminum head.
