Well, actually, this is my first pattern plane and I don't expect to be in any contests now or ever. I just liked the looks of the plane and all I wanna do is some knife edges, rolls, and whatever.

I just want an engine to get me airborne and at least hold a knife edge. I'd be pretty upset if I paid $320 for the OS 120 surpass and found out it doesn't actually run (with no problems) like my OS 91 surpasses do!

I'm sure the 120 would pull it better but I'm not entering into the world championships!

Maybe I should do a poll on the OS 120S-E surpass w/o pump and see if others have any problems with that engine.
