I did try with and without the breather connected to the inlet, no measurable difference in rpm. Togatoga will be happy :-)

Hi HS, thanks for posting the result- I reckon in the end, real world figures count, not theories. I remember Brian Winch doing this mod to his engines many years back and recommending it to readers.
I tried a 15x7 apc with the 125 and found that it didn't perform as well as the 15x8apc.The engine was louder but the plane didn't fly as well! I'm going back to the 15x8.I agree with hobbsy, I think the 15x6 is too little prop.
