    Boat Mods

    Guys;

    I have modded about 10 FE boats to date and built over 25 ( gas / scale) in total over 20 years or so...one thing that still amazes me is that more people don't use expandable foam as structual material for re-inforcing hulls. Its the best thing going,,,I just used it again in my Super Hawaii mod and it makes the hull strong as a rock with almost no increase in weight and adds flotation:D .

    Its a win / win situation all around. Just be sure to use the LOW expansion stuff and add it in stages otherwise the hulls can be pushed out of shape.

    Also , once its dry and has reached full expansion , you can cut it, file it to whatever shape you may need to install batteries etc.

    Just some advice on what has helped me out over the years.:)

    doesn't it suck up and hold water?

      It depends on what type it is... True Two-Part expanding foam works pretty well... just don't get it into a confined space... or POP goes the seam...

                  The reason I never used it was that everyone says that it will expand when exposed to the heat from sitting out in the sun. If this is incorrect it would really be nice to use for abs hulls.

                            Doby,

                            Great Tip, thanks. It's nice that you have already done the years of data collection on this.

                              I have also used the expanding foam in my classic hydros kit made the hull solid and so far its had no problems in the sun and its been in 100 degree weather. and with the crazy temps in colorado somthing would have shown by now!
