  Steve,

  I have a Viper 91 by Zimpro with the OS91 Fx with perry pump and running S&W 25% nitro with a 13.8X10 apc 4 Blade prop and plane will go out of sight.. It has been there for a demo.. Weight is a little over 7.5#..Your right the OS91 is a great power house..

     If your thinking of buying a 90 size pattern plane, which I like to use in the winter as a sport practice plane and learning new maneuvers like the rollers in F-05, the Ca Epsilon is perfect if you like to build, and no I'm sure not sponsored.
     Took me about 5 weeks to build fairly simple build it is a kit so no hardware is included which I really liked.
     Setup was an OS 91 FX, Perry pump, 14X8 apc prop, Coolpower 15%, Jr 4131 servos, finished weight was 7lb 91/2 oz. including 2 1/2 oz tail weight,
       The flying is great, snaps that stop instantly and dead on heading, knife edge is perfect NO mixing, I did have to reflex ailerons to get the up and down lines right, rolls very axial, stall turns was little harder than some planes I've had but just a timing thing, flat rudder turn are dead on, landings and take off are easy as they get surprisingly needed to keep a little power on for landing, no tip stall tendencies.
     If you do build one of these I would shorten the ailerons down at the root by at about 3 to 4 in. the throws they give you are way to much for pattern or at least for me, I have them set at 11 degrees the manual calls for 20 for sport pattern.
     I only have 4 flights on it now so there is still some trimming to do probably moving the cg even farther back could help, will probably move the rudder servo to the tail to remove the weight I have now then the battery if needed. 
    YS guy's if you have a old 91 laying around I would think this would be a good project for it, I'm not a YS person but would think the 110 would be way over kill, the OS 91 FX has more than enough.
     One of my goals last year was to find inexpensive but great flying planes for beginners,  I feel that one of the problems we have getting more people involved in pattern is expense and the sportsman or intermediate or even higher classes really doesn't need a $2000 plane to be competitive, I have flown the Swallow, Excelleron, Quest, I feel that in the right hands and their trimming this plane could be very completive in any class. The Epsilon is an exceptional plane.
