Still running the 10% nitro, 18% oil- Full throttle with the 15x7 was 9670 rpm, about 400-500 more than I expected with the baffle in place. tomorrow i will switch to 15% nitro, 16% oil and I will check again. Should hit 10K with that fuel. I'm keeping in the baffle for sound reasons. I am Cd'ing a contest June 12th and will have a Db meter on hand for the contest and a few days prior so I will post the sound readings also. The 15x7 is definatley the prop for pattern, but for 3-D and hovering, I think the 15x6 will be the prop of choice. we will see after the contest.

changed to the 15% nitro and could not get any rpm gain. I will richen it down to 9500 and fly the tar out of I guess. The plane flys awesome.
