I have a mighty 110 in mine. One of my favorite planes. I think the 120AX would work nicely also. 16x6 or 17x4 prop would be the ticket. This is one of my favorite planes. I love the UCDs. The are wonderful. One of only 2 or 3 planes I've ever seen that will do a rising inverted flat spin. It wouldn't do it with the Saito 100 in it but does them with the YS. I think the extra power is really worth it. Also helps a great deal with waterfalls.
Thanks
