Ater some internet searching, I found some posts where it seems like some people have been replacing the stock head and tail assemblies on their AXE 400 with these complete metal head and tail kits that are made for the TREX 450. I had a mishap and busted the stock head block on my AXE 400, so I am thinking that rather than pay 10.00 + shipping for a stock head block from Tower that I would rather buy one of these complete metal head and tail kits....

Before I do, I just wanted to make certain that these are just a straight drop in replacement and will work with my AXE 400 with no other modifications..... Could someone please answer this question for me. I think from what I have read that they are.. I will just need to use the stock swashplate assembly.... Correct?

Here are a few that I am looking at....
