Very good question - is it not because polymer/plastic blades will be TOO STRONG ?? :stupid:

The reason I say that is that if graphite/wooden blades hit something (including a human) they should break, thereby acting as a "sacrificial component" and thereby saving (hopefully) the main mast, clutch, engine etc ... and possibly saving someone's life??

I noted that here at our flying club in London, metal rotor blades are prohibited - can you imagine what damage they could do?? I'm sure polymer/plastic blades spinning at 1600rpm are as lethal as metal.

I know normal blades are potentially lethal as well, but maybe the polymer/plastic blades are ven more dangerous??

Just a thought ....
