try 11x7 if you want speed you must be able to get to the engines max HP
next 11x8
12x8 is too much load
"too much load" is exactly what it is. It feels heavy and RPM's are lower than they probably* should be.
Looks like ihave my work cut out for me. And I need to get more props.
*naaa, they are too low now that Ithink about it.
