Sweet...thanks for the links. I got mine off of eBay and it did not come with the upgraded tail...I glued them on good and poured some thin CA in the tail halves...I can't get the tails to break using hand pressure, but I think I might cut off the bottom sheeting and reinforce it. Since I put an OS 160FX in it, it couldn't hurt. I will also use the 1/4-20 nylon bolt trick on the wing halves. Thanks again and happy landings.
