Weird, I totaled mine earlier this week...must be a bad week for Axe 400's. I got too ballsy with my less-than-adequate 3D skills haha. Mine's pretty mangled :-(. Here's the head that I current'y have on my used-to-be bird: http://www.hobbyking.com/hobbycity/s...idProduct=9790. You'll be happy to know, that despite a full speed slamming into the ground (with a bounce), this rotor head stayed intact (except for the flybar, which tried to wrap itself around the head. Silly flybar.

PS: You'll need either the original Axe 400 swashplate or I think the metal swashplate for the E-Razor (or Genesis...can't remember) from Xheli.com. I've never tried the metal swash from the Xheli helicopter, but it looks like it'll fit...you could always get both, and if the one from Xheli doesn't fit, then just put in the stock swash from helimax, cuz that's what I'm still using. Also, be sure to adjust the linkages to the washout arms (on the head assembly), because upon installation, they won't be set right. Both arms need to be level when your throttle is at 0%.

PS #2: As for a good tail assembly, you can check Xheli.com They have a head and tail combo (i'm pretty sure). I don't have any experience with that particualr product, so I can't say if that'll work or not. The head looks exactly like the one I got from HobbyKing. Since I crashed face-first, my tail is fine, so I don't really need one.
