The lite-ply fuse breaks just aft of the bulkhead at the back of the wings on a fast landing. Its partly due to the ply being a bit weak and partly due to the wing pivoting on the front peg as it hits the ground which puts quite a lot of sideways force on the rear wing mount. A full fiberglass reinforcing job will add quite a lot of weight to the plane at the back. I've found that all I needed was strips of fiberglass tape (package strapping tape, the staple of the foamie world) to reinforce the fuse. I have three lengthwise ones and one wound around the fuse to hold them in place. If it is done carefully then it doesn't look like a kludge and the tape is at least as strong as fiberglass and epoxy but a lot lighter.
I also use triangle stock to reinforce the butt joints in the fuse. I believe the instructions say that you can build the plane with a fixed rudder. Don't. Servos are cheap and the rudder makes the plane more fun to fly. (I've also been thinking about changing out the single aileron servo for a pair so I can have flaperons -- its one of those "get round tuit" jobs.)
