I put mine in the rear.Before you attach your horizontal stabilizer you can reach down into the fuseloge and see the wood is missing ans in sort of an oval shape.Cut you out a piece of thin aircraft ply or whatever you chose to fit as good as possible in that open area on both sides.Then cross brace with balsa 1/4 stock for strength.Now you can cut out a spot for you servos that will be solid.One on each side.I used 9001 servos on mine.Also used one rudder servo and attached the tailwheel to the rod with a swvel clevis.Hope this helps.Tivey
