I was wondering if anyone had looked into putting an SMA 305 out front of an RV10. Seems to me if the cost were right that you are getting a pretty comparable power source at lower RPM, better performance at altitude, similar weight to the IO-540 from Lycoming and fewer moving parts. Considering the ultimate plite of 100LL I would suspect that this might be a good direction to go. Given that Cessna and Maule have looked into and certified it in the 182 and M-9(not sure about cert yet for the M-9). Both of which could use the IO-540 I would suspect that you could do the same in an RV10. I would like to hear some other thoughts on the subject....
