The moral of that story appears to be "if you know what you are doing and fully understand the products and risks you can do fine, but be careful anyway" Is that close? I know what you mean about people trying to re-use a prop after a ground strike. Just because there is no externally visible damage they figure it's still good to go...

Where are you obtaining those ZM (ZN?) carbon props you posted in another thread? Whe I get back I'd like to look into a couple of those. Thanks.
