All,

I have a Twister coming in next week and I've got two candidate engines for it: SK-80 and 0S 46FXi (w/Tower muffler). With this plane, I am mainly interested in pattern-type flight with good slow flight characteristics. As I read the forums, I see a variety of weights being reported and I wonder if I'd have to add much tail weight (I don't want to add any) if I strapped on the 28oz SK-80 as opposed to the 16oz OS. Will the SK-80 take this thing way out of its designed parameters? Based on most of the stuff I've read, the 46 would be a better choice. Any input/suggestions would be greatly appreciated.

Thanks,
Gary
