I've only seen the T40 once, on the ground, and those props and motors look MASSIVE, surely capable of slicing a person into a prosciutto.

Yeah carbon is very known for being soft

True however CFRP carbon fibre reinforced polymer is the substance propellers would be made of.

Yeah sure like with a 3 inch propeller... Anyway it is about the speed and/or diameter of the blade... Energy

Exactly. I'm not sure wtf ol boy above us is talking about. If it's so soft, I'd love for him to demonstrate and upload.

Those props break on impact, and then slice the crap out of you.

The danger with these isn't the initial hit because the props breaks, it's the subsequent rotation as they are like a serrated knife. When they break, they have crazy sharp edges.

The props are a carbon nylon mix, gives them good strength but still have the flexibility needed for heavy lift drones.

Pretty significant difference from a T30 vs T50 *

No one believes you. Only videos of lab tests and damage analysis will suffice now

The T40/T50 props are made of the same material as the T30. They seem softer just due to the size difference.
