I have ordered the Saito 91 for my Funtana. It depends how you wan't to fly it. The recommended Saito 72 will be fine for stooging around and most 3D stuff but the 91 will give lots of vertical power and good punch out from the hover. I fly electric 3D foamies which have great power to weight ratios, and thats what I want with te Funtana.
