Two engines made on the same production line, in a CNC process, cannot differ so much from one another. The range of RPM demonstrated on the same prop, can be no more than 300 RPM; between the weakest engine and the strongest.
Not even a quirk can explain this.
I said I couldn't explain it - Just reporting my results. Never threw a blade either. I have since replaced the 10X6 with an 11X6 with good power (no tach readings yet).
Where did you see me say the two engines were made on the same production line? One is an ASP (12 years old), the other is a Magnum (2 years old). Both with factory equipment (no mods or tuned pipes). Although I've never seen another ASP .40, other ASP owners I've met have reported extreme pleasure with their engines (.61, .91, 1.20 size).
