RE: Welcome to Club SAITO !
Mike early.............go with the Saito 82, same as the 72 but has 20% more power. Love the sound of the 82. You'll be happy. A friend of mine had it on his Funtana 40. He also have another one on his Extra. I don't think there's too much of a price difference.
My Corsair won't be flying before the spring. I still have work to do on it. Meanwhile I ordered an MA 14X7 3 Blade too. I will have a Graupner and an MA to compare.
