There is a reason for that, if you build the plane stock you will need more than a 45 for good performance. I first flew mine with an ST45, and I had to build a lot of speed before doing any vertical maneuvers. I don't have to worry about that anymore with an ST75. Remember this plane isn't that much smaller than their 60 size (90 really).
