    Question T3 RXP-X Riva *ADJUSTABLE* Trim Tabs

    Wanting to see where others running them have them set and any feedback on handling characteristics of different settings. Particularly where you have the front pivot point set?

    Not exactly the same, but I'm running adjustable tabs and moved them to maximum bow down to help holeshot. Didn't feel much difference, but scrubbed 4mph of max speed!

    Stability felt better and turn in more aggresive, but I'm no pro bouy rider by a long way.

    I have gone back to one click beyond neutral (bow down) as this gives a quick "on plane" time and doesn't drag.

    Might be diff on RXPX, but physics is about the same.

    Be sure to look at the hull from the side as you don't want the tabs to be below the hull or they will drag.

    Thanks for the info.

    the Riva tabs are a little different. The mounting plate is up higher than the hull so no drag. The front pivot point is adjustable about 5mm, and then there is rear adjustment via the buckles. So you could maintain the same angle but bave it flush at the front, or set up 5mm at the front.
    I have played with them and changes make a massive difference in the way the ski handles, plains and feels at high speed. Am happy with where they are set now but guess I will keep adjusting.

    I just installed my trim tabs ( r&d ) about a week ago and have noticed the ski is more glued to the water as well as more responsive.

    Got any pics? The reason I ask is because the pic on the website is the worlds smallest picture: http://www.4-tecperformance.com/inde...oducts_id=2041

    And what does R&D mean by "extended length" trim tabs?
