    What will turn more RPM?

    Solas 15/20r out of the box vs Skat 15/19R out of the box and 81mm ring
    Assuming Rude Charger, Rotax, etc....
    Thanks

    which ecu? i would guess the 3 blade would be faster but possibly turn less rpms...you would need to bend either one i am sure.

    out of the box i dont know but u can get either prop 2 spin 8600 r's with a 80 or 81 ring by tweeking ur prop 2 ur set up a lot of people like the 3 blade because it hook up better on top some say it faster some say it not havent tried the 3 blade yet but i think i'm going 2 my 15/20 isn't so great out of the hole

    The three blade loves rpms. My set up is Rude SC--Rive Stage 3 ECU andall the other stuff to make it work. I am running a 80 1/2 ring--turning 8550 rmp and 83mph.
