    DIY OPAS block-offs. poor mans alternate

    i want to run a riva straight threw exhaust on my rxp. so OPAS removal needs to be done. funds are tight!

    i didnt fancy just plating off the holes for the padles. i would really like some RE blockoffs, but to keep costs down i made some plates up to lock the padles in their "strait" position.

    the "arms" on the plate are from a tornado jet fighter (some scrap stuff from work)

    the logic for doing all this is i hope the padles will help the hull track better in the surf, than not having them at all.

    you are on the right track, I took black lexan plastic and made a set, you have to take everything out of the hull, and you will have room for the thu hull exhaust,
    go to riva racing and look at the how to section to pull everything out,
