CUSTOMPC,
I GOT THE SAME RPM READINGS WITH MY OS 91FS2 ON MY SUPER SKYBOLT, GRAUPNER 14-7 TURNS 8400-8600. IDLES RELIABLY AT
1600RPM, I HAVENT TRIED ANY OTHER PROPS IN FLIGHT BUT THIS COMBO IS IMPRESSIVE ON THE SKYBOLT. JUST THIS WEEK FLEW FOR 23MINUTES AND STILL HAD SOME FUEL LEFT. ON A CALM DAY I CAN HANG ON THE PROP AT HALF THROTTLE. I TOTALLY AGREE WITH YOUR ORIGINAL POST AS I HAVE BEEN LOOKING FOR SOMEONE ELSE TO SEE IF THEY HAD TRIED THIS PROP/ ENG COMBO AND WHAT THEY WERE TURNING FOR RPM. SOUNDS LIKE WE HAVE THE SAME RESULTS. -AARON-
