I have no experience with that plane in particular, but I can tell you that most 40 size planes fly very well on a Saito 72. Some even do well on a Saito 91. If it were mine I'd give the Saito 72 or the YS63 thefirst try and then go to the 91 if you need more power. The other way to determine which engine, lucky for you you've got a nice selection of engines to choose from, is to build the plane and then see which engine helps to get the correct balance.
