I finished up with the break in portion of the Magnum 91 FSR engine on the stand today. At least I hope it is. Ran close to 3 hours with varied throttle settings. Not much WOT though. Didn't want to annoy the neighbors too much. Used 1/2 gallon plus of fuel. Transition isn't as nice as I would like to see it yet. But that will get better. With 5% nitro and 20% oil it ran 9200 peaked. With 15% nitro and 18% oil it was 9500 peaked. Had hoped for more of a rpm increase than that. Using a MA 14x6 prop. This is my first experience on a four stroke with the recirculating waste oil back thru the engine. Any thing different about them or little quirks as compared to a Saito maybe?
Now I am waiting for the planes to show up. Haven't asked lately what their schedule is.
Can any one tell me how much lateral balace weight it took with a 91 fs mounted horizontally? Thanks
