Dave Patrick ULtimate 1.20 Bipe engine????
OKay, for all those that are not quite sure how to power your Ultimates. I have spoken with Dave a couple of times. He has run qutie a few different engine combo's on the Ultimate. He tells me that of all the diff possible combinations, he prefers to fly with the YS 120 FZ. He says that it does have unlimited vertical, and is the best overall performer. If you set it up like he says to. I have decided that is the way to go. Who better to ask, than the man who made the plane. I will let you know how it flies, when I get done with mine.
