    Sounds like someone is working on something big.

    Most of the GPs were running 14/20 J's or repitched XI's Dave at Impros steered me towards the XI he felt it perfomed better than the Concord. I never ran any Skats

    Talk to Dave at Impros I bet he could steer you in the right direction. I have not seen the older ones bent that high but I am sure it could be done.

    What is the length of the race course?

    I have a solas J that carl at IR brought down to 11/17. I can't see any reason why one of our prop guys couldn't bend one steeper than usual. There are also Skat's and nujets to look at. Maybe one of the earlier GPR props would fit as well?

    And. . . What are you working on!?!?!!

    14.5/21 skat might work if you have over 240 hp
