I have a YS110 in mine which I think is several ounces lighter than your engine. But I think it has about the same power. I used an APC 16x6 at first then switch to a APC 17x4W later. That's the prop I presently use but I like both. The 17 hovers easier but I think all other stunts are better with the 16. I'm back and forth on which prop is really the best. I also mounted the rudder servo in the tail. This helps with the CG. Mine balanced just right without any additional weight. There is a thread in this forum somewhere a few pages back that has some 300 posts. It discusses a lot about this plane and what you should do. Most people are moving the rudder servo because the pull/pull configuration has a tendency to jam up. I built mine that way right off so I wouldn't have the problem. I think this is a real nice airplane. Not too many people have it but I like it the best in my fleet. I also have a Funtana 90 and a UCD 60. This one is the best in my opinion. It flys the easiest and lands the easiest and does everything I like to do better. It is simply the easiest plane to land I've ever seen. It will do an inverted rising flat spin that is really flat. It does very good waterfalls. I'm still learning the rolling circles and harriers so I can't say it does them but I'm certain it will. I can just about do these but I need more practice. Something that has been hard for me to do lately. I think you will really like this plane. I do.
Thanks,
