I am one of the big fans of the Funtana 90. Make sure to use strong servos, remove any slop in the control surfaces (even if it means upgrading the hardware), inspect ribs through the bottom transparent covering (some had cracket ribs that needed fixing), and FLY IT 3D SLOW, or it will probably flutter and crash (according to some posts on the various Funtana 90 threads).
The two of us at our club fly the F 90 with Saito 1.50/APC 14x6, Futaba 9402 servos, upgaded hardware, and we LOVE the plane. Again, it's a light 3D plane, fly it slow and land it smooth to avoid dammage.
