I am about to build my CMPro Swallow so that I can learn to fly pattern. I am thiking of using a MVVS91 2C for the plane, would this set up be sufficient or over powering for the plane? Also what would be the best prop size for pattern flying with a 90 2C engine?

I to have just purchased a CMPro Swallow. I was going to put an OS91 FS in it. Some people have told me it wont have the perfomance with this engine? I like my 4 Strokes will I need to go to a 1.2 FS?
