hi again!
Today I tested my ASP with a different cyl.head. I replaced the standard cyl. head with the one that comes with the O.S Hyper. The result was a increase in power from 10000 to 10300 RPM on APC 14x6. The result was better power and of course far better cooling for 3D. Maybe I will also test the ASP 52 with this cyl.head in my heli, just to see how it will perform compared to the O.S Hyper.
