I tried flying mine outside this morning (with ribbon) and could not get it to stay up more than a few seconds, the pitch oscillation was back with a veangance! This evening when I got home it was really calm out, so I rigged up a horizontal stab similar to yours. Basically I just quickly cut a triangle out of card stock, cut a slot in it to go around the prop and taped it onto the tail. I also removed the ribbon. I bent the end of the card stock down about 30 degrees and it works fantastic!! The pitchiness was completely gone at anything above half throttle and as a bonus it climbs MUCH better than before. It climbs out quickly now, so fast in fact that I was having to drop to less than half throttle to keep it from getting away. When dropping below half throttle, it does oscillate a bit, but not as bad as before. It also seems to dampen the turning, it doesn't react as harshly to turn inputs as it did before. I tried flying it inside the house and it's flying too fast, but for outdoor flight this mod is a definite must! It would seem that the stock tail is angled upward too steeply and this mod compensates for that.
