  Thank you  for all of the input.  I think that I am going to use a FZ110
from YS.  Are there any comments on what you guys think that the performance
will be from that engine plane combo?

    Scott,

    I tried a OS Surpass 91 w/Pump in an 8-1/2 lb plane (VMar Avenger - Not
recommended for Pattern) to compete in Sportsman in 2001. The engine could
not pull the 45 degree up line for the 1/2 reverse cuban eight. I replaced
it with the 91FX and had no problem using the stock muffler, but again the
weight was 8-1/2 lbs. More weight than that and you will need more power.

        Hello,

        I use the OS91FX in a pattern plane and over the weekend Dennis Hunt
from Zimpro had me do a test.. we ADDED lead to my 91 size viper and brought
the dry weight up to 9.5 lbs and went and put a flight on it to see about
the vertical ... And it went without a problem.. I'm running a APC 4 blade
prop and 25% S&W fuel... also have added a perry pump to the set up last
year runs great..

          I am going to be putting together an Exceleron 90.  I have 2
different engine options.  First is an OS FX91, second is an OS FS91 Surpass
w/pump.  Both are NIB.  I have flow previous planes with a different 91FRX.
I am good with engines so I am not worried about any finicky engine issues
with either one.  I have 2 two meter planes right now.  This plane is one
that I want to be able to get home from work, grab it and go.  The 2 meter
planes take a little bit more preparation to get them going quickly.  I want
the plane to fly well with a good power curve.  I know that the 91FX will
want to be flown a little bit faster, but how much I don't know.  Also would
the FS91 II Surpass be enough to fly the plane well.  I will most likely be
flying the intermediate pattern next year, so it doesn't have to be oh my
God outrageous performance.  But I don't want tit to be a dog either.

          If there is anybody with any time on this plane that could shed
some light on the situation it would be greatly appreciated.
