Do a search on the Funtana. There is a thread with comments from some of the early fliers, and comments on what engines to use. I am finishing mine later this week (waiting for a flight pack) and am using a Saito 72. These planes are hot, and flying off the shelf. My LHS ordered and has already sold 5 out of 6 in just 5 days. I bought mine last Wednesday and got the first he sold.
