RE: Something Extra Hardware
I put my servos in the back of the fuse, just infront of the tail. With a little care they can be placed so they both sit flush with the fuse side. I did this after I had flown it several times. It can be done with minor "patching" of the covering.
If you don't want to go that route, I've seen a couple use wire inside the tube, I think it makes for a lot of extra drag on the servo, but it does work.
