I haver just a little time on a Funtana with the YS 1.10, and was not overly impressed. It flew OK, but not great. I have even less time flying an Extreme flight Yak, but I know several serious 3d'ers that were impressed with the Yak. I've also heard the Yak will do good precision as well. From what I know I would get the Yak, and I think Extreme Flight has a combo with the YS 1.10 also. Tom
