    bounching bow or "Porpoising"

    Chuck
    To reduce or eliminate the bouncing or "Porpoising"(not sure that is a real word), try moving your batteries forward. Do it in small increments until you find the right placement. The bouncing should subside.
    These boats are very light in the bow, so shaft and rudder trim alone, are not enough to get her done.

    It would be great if you could fit some trim tabs on the boat, but the design of the hull makes it pretty tough. You can check the bottom to make sure it is straight. If there is a "rocker" (high spot) or a concave indentation, that can affect the boats trim and ride, not to mention speed.

    I got the bounch out by moving the batteries forward a bit. Cats like to bouch, so we have to provide some form of resistance that can off-set or balance the lift from the tunnel and the prop.

    These boats are much like their big bothers, and prone to flight. If they get airborne it is not good!

    You may have already tried this, don't know, but it worked on my MG.

      Flatten your iride pads first. Then trim the boat.

          Go read the post by the guy who runs his at 50 MPH! He says pull the batteries way back and put the strut down.
