    what pitch prop?

    I need to know what pitch prop i will need to run on my rxp.
    The mods i have on the ski are shown in my sig below.

    I have a 4 blade 14/19 and a 3 blade 15/19.
    which would be the best prop to run on my setup, im looking for more accceleration than topend so im guessing the 3 blade.

    The rotax ecu is the 8650 rpm limit.
    Thanks scott

    i would try the 15/19, on my mates rxp with mods he uses a 15 something and it goes well out of the hole and up high

    3 Blade will give you more acceleration and less top end. 4 Blade will give less bottom end but about 2 more MPH on top
