RE: Welcome to Club SAITO !
thrashin,
I have both and can't tell any difference in the two engines. I have to say that the 1.25 has not been airborne yet. The performance varies between airplanes. To accurately compare, they would have to be tried on the same plane. However, on the bench it doesn't seem to have any more power. The 1.25 is fairly new and seems to like the 15x8 APC better than the 16x6. There is not that much difference in the props. Maybe it will change with more run time.
