Whew. I was waiting for someone else "out there" to finish one up and give an opinion.
2.5 ozs on the tail???? Where did you put your battery and radio? I had to add a bit of tail weight as well. About an ounce, but I could have moved the battery. You may even find it flies better even more tail heavy yet. But be careful, behind the tube it gets to where a little bit goes a LONG way, it's right in the area of the aft limit. But BOY does it snap clean back there!
Well I'm glad you like it. The rudder mix is not much, but it is a little odd from what I found. My guess is the counter balance has something to do with it. I'd love to hear your numbers and compare, I have settled at 4%. 5 is too much, and 3 isn't enough.
Let me know how it does in up and down lines, tracking, etc after you put about a case through it and really start to get the feel. Curiousity is killing me to compare notes down the road.
Wait till you try masters with it [8D]
Have fun and burn some fuel,
