According to the guys over in the fun flying forum, the Accel Katana is one of the best on the market. From the post it is about tied with the EF edge. I can speak for the EF edge which I flew last weekend. If the Katana flies anything like it, then you will not want a Funtana 40, which I can also speak for. The profiles fly much lighter and are much easier to fly. So instead get 1 Accel Katana and 1 EF edge for a backup, and forget the Funtana. Just my $.02. Good luck with your new engine and plane.
