it ended up pretty nose heavy. I moved the elevator servo to the back of the fuse and placed the receiver battery as far back as possible. I also added tail wires to strengthen the vertical stab. Even with all these changes, I still needed 2 ounces of lead inside the fuse before gluing the vertical stab in place. On my rebuilt Stik, i placed the elevator servo even further back and only needed 1 ounce of lead. I like my models slightly tail heavy though, so I could have likely gotten away with less weight.
