Just out of curiosity I checked what was recommended by Tower. They recommend the 12X9, 10, or 11 for a tuned pipe.<BR><BR>

<P class=EC_MsoNormal><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: 'Tahoma','sans-serif'">One of the sport flyers in my local club wants to know what prop he should use for an OS61FX on a MACS long quiet pipe? Setup is in a Sig King Kobra with retracts. I couldn't 100% for sure answer him since the last .61 I ran was a Hanno special on a Hatori pipe with a 12X11. I have no idea how strong the newer OS's are in comparison. I'm guessing 12X10 on 15% nitro fuel? Anyone have a definitive answer?</SPAN></P>
