Excelleron with OS 91FX in Intermediate ?

[Randy]

I order a Tiger Shark 1.20 for my excelleron90.  Should be about right.

  Bruce,
      Thanks, that's what I am concerned about.  The OS 91 FX most likely will require a pipe to do the job and the Excelleron
  is not set up for a pipe.  I may have to resort to a larger 2 stroke engine.  Bob Pastorello is using a Super Tiger 2300.
  Not sure I wish to go that big !
  Thanks,
  Paul

    I have a scratch built Typhoon 909 that weighs around 8 to 8.5 pounds.  The "Littlephoon" has 909 square inches of wing, about a 70 inch wing span.  I fly intermediate at 5500 feet MSL.  The YS91 did not have enough to fly the Int pattern, because of the two maneuvers you mentioned.  I put a YS 110 in the Littlephoon, and now I have plenty of power swinging a 15X8.  I have no experience with the OS, but I would think the YS would be a little lacking. 

    See ya,

    Bruce
