My 1.08 gets compliments on the sound it makes when I fly it now. The 16-6 prop pulls better at lower revs, and with the pump working right, it never sounds thin or tinny like it used to. I am totally satisfied with the performance of the engine. I just need to put it on a lighter plane by about 1 lb to get the performance I want. Now I'm itching to get to that G2300 that's still in the box!
