Over deze boot

So I've got the Sea Urchin built to a point where it's ready for filling and sanding. I think I could have done better with the initial build but I'm still learning the terminology and techniques. I'll add a few photos tomorrow and tell you what I intend to do next hopefully If I suggest something wrong you folk will step in and point me in the right direction, wish me luck 😀

    I must open my Sea Urchin pack and take a look at it.
    The character full rudder that attaches to to outside of the transom is easy enough to hinge (I hope) but deciding where to place the operating rod to the steering servo will need some serious thought.
    I have never seen a radio controlled Sea Urchin in use, so I need to consider the options.
    The push/pull option with the operating shafts passing through the transom would be a good mechanical fix, but making them water - tight will be the problem !

    I'm going to give that a go today after testing it out on some scrap, I don't want o be lumbered with spending time removing a failed attempt again.

    A couple of the old/project boats that I have bought, people have used car body filler and built up above and below the shaft/around the keel and blended it away to nothing ahead of the tube exit point on the underside.
    Whether or not that's a recommended option these days I do not know, but I have a few like that.

    I’ve just done a float test after an initial build like yours. It leaked!
    So I followed advice and used a two part epoxy on the outer joints of the prop tube. Then, having reduced the leaks a bit, I poured a tea cup of “Seal and Sand” IPE polyurethane wood glue. Any cheap white wood glue will work. Then over the next day I liberally brushed it all over the inside of the hull.
    No leaks and ready to paint.
    I hope that gives you a nice dry boat.

    just having a few problems with the rather long exit of the prop shaft, try to get a smooth finish for the hull but the fibreglass option didn't work that well, have now removed it ?

    I haven't decided on what colours to do mine either yet.
    I've got plenty of time to decide though, got one or two others to get sorted first.
