Put a bigger prop on it and slow it back down to about 7300--7500RPM.

I can tell you from experience--they don't last long when you get over 8800RPM on the bench. I don't know how long it will last at 8000RPM, but after seeing one exploded--I don't think I'll push them past 7500RPM anymore.

Turning a bigger prop at lower RPM can provide just as much thrust or sometimes more than the prop you have now.

Put a bigger prop on it untill you get back down to 7500RPM. [sm=thumbs_up.gif]
