    Adding Rude SC to my stage III, where to start on 15/19 skat prop

    I'm adding a rude to my stage III today and want to know what "Tweek" I should start with. I want a drag ski so I'm staying with my 15/19, I was thinking maybe + 3mm to start then tweek from there. Thoughts?

    Thanks,

    Alex

    What SC are you running now?
    What RPM's are you getting with it?
    What is your current prop bent to (from out of box)?

    Danny,

    I running the S3 now. I'm getting 8500 RPM's on a re-pitched 15/18.5.. I bought a new 15/19 to experiment with, I'm passing the good 'ol 15/18.5 drag prop to another friend with a stage III.

    I have a similar setup, just not the ECU...My 15/19 is done back a HAIR ovr 2mm from out of box. I would say 3mm is a good starting spot for you....

    Alex, being that you are in the Miami heat/humidity i would start with 2.5 mm.
    This is based on using an 81mm ring in your nozzle.

    My Ski was right at 8600 with a stock 15-19R. I added 1.5mm and am dead on. IMO I would not start with more than this. I run a 81mm Ring. Also you never know were the 15-19R is really pitch from Rivas as mine were different. This is why I have 2 of them.
