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?<br /><hr />More immediate than e-mail? <a href='http://www.windowslive.com/messenger/overview.html?ocid=TXT_TAGLM_WL_Refresh_instantaccess_042008' target='_new'>Get instant access with Windows Live Messenger.</a></body>
