RE: AMD Hawk.
SJN, looking at your elevator/rudder servo mounts, are you essentially building them into the airframe such that you would have to cut away fiberglass in the future to get access to them? How can you get to yours?
I am trying to think of a way to make them accessible...such as with a removable panel in the top of the thrust tube (still awkward, but at least workable) or a panel near the rudder-fuse interface (might weaken the structure quite a bit).
