Would you use this prop?

I have a 30 X 13 mejzlik prop, running on a DA 200 quad, and on the last flight, there was damage to the motor after performing a snap. This resulted in the spinner back plate (and the spinner/prop) not turning true, the prop hub was wobbling, with everything in front of it, and it damaged the spinner back plate (Falcon), and the cowl. The question.

On the propeller, on one side, where the spinner cut out is, there is a under 1 mm deep groove that is about the length of the blade from front to back, where it meets the prop hub.

Would anyone just trash this prop / is it too risky to use again, or

is it ok to use. there was never a prop strike, but, it was "damaged" from the untrue spinning.

I can post a picture of it, when I get home.

What I have done is filled the groove with CA.

I would post a pic.

I trash any prop that gets damaged in any way. A new prop is much cheaper than a new engine if or when that prop breaks. And believe me with some being 200 bucks or so it is not an easy thing to do.
Two weeks ago I had a nose over after landing, prop to ground strike and killed engine per typical. I immediately pulled the Biela CF 32x12x3 and replaced with a temp 2 blade wood, that is a $200+ nose over. But, if that prop came apart in the air it could kill the $3K Valach or worse on the ground to an individual.

Cam, there's way to much time, effort and $$$ to trust a damaged prop,,, its bad enough having to stop flying for a few days while the engine is sent in for a check up but that too is a necessary evil when an incident like this occurs.

Sounds good. I will not use that prop. I will post a picture, once it stops raining. I just needed to hear that from you all. It was my inclination also, but it is always better when there is a quorum.

kinda sounds like a new crankshaft is order.

kinda sounds like a new crankshaft is order and new bearings,,, etc.
