    OK, so is the prop just spinning on the brass hub? Kind of hard to imagine how this could happen, maybe the prop was not machined/assembled properly…Or, perhaps the aluminum is cracked allow it to pull away from the brass hub…
    OK, I’m confused….You have one prop labeled as the bad prop, but it looks like a good prop….The other prop is labeled good, and it looks like the one where the brass hub has separated from the aluminum propeller casting…
    Does the engine vibrate using either of these propellers?
