was just having a look at the propellers when I came across these...

reading more on wooden props gave an idea that they are stiffer than plastic props...
I was thinking of trying them out.
has anyone here used them before...??
would like to know how would they compare to existing plastic props....

They are good but thinner at the middle especially
No problems run good

thanks abhay...
would like to know how do they perform compared to regular APC props and is there any difference in thrust and efficiency..
