RE: Little Screamer and E-flite brushless ESC
Hi Erik-
I've heard nasty sounds when a motor is being over-propped, which is why I suggested trying a different prop. I still think that's a good idea. Maybe also try a slightly smaller prop, such as a GWS 7x3.5HD.
Without at least trying a couple of different props, you don't have much data with which to analyze what's happening.
May we presume that the motor sounds OK when you run it without a prop?
