WoodsyMatt,

I dont know bout the whole 4 blade prop thing. I know my Uncle Dave was looking into getting 4bladed props for 130 but couldnt find any he liked. I know he used the two blade for flying and pulled them off and put 4 bladed on for static compitition.

I know his 130 flew great on the 25 la's w/ 2 bladed props.
