Excelleron with OS 91FX in Intermediate ?

[Rick Kent]

Anyone here think a 1.08 2 stroke would be sufficient to make up the
difference between  a muffled vs. piped .91 2 stroke? I have an ASP 1.08
lying around I may try on it. I also have a Thunder Tiger 1.20 2-stroke if
that won't work.

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
