    Hi shipmates,

    Today I received my stinger by post, after a lot of cutting and filing I got it to fit and made it adjustable up 1 degree and down 2 degrees.

    I have cut down the rudder as a bit too deep.

    I've fitted the motor and had a bit of luck with that by changing the mount to a narrower based one I am able to fit it snuggly between two of the spray rails.

    I have just epoxied the bent shaft into position.

    Regards Roy

    Hi Shipmates,

    RECAP
    After a few too many bad experiences with expanding foam I though of a less dangerous way to stop my boat sinking (experimental).

    Basically it is polystyrene balls and acrylic paint (white) mixed together so the balls are covered and stick together (patient pending) joke.

    Thus will follow the rough shape of the hull, but will take some time to dry.

    UPDATE
    Unfortunately after a few days the stuff was only dry on the exposed surface.
    So I had to remove it all by hand and wash out the interior of the boat before refilling with dry polystyrene balls and fitting a solid polystyrene bulkhead, which appears to have worked ok.

    Regards Roy

    I think I read an article on this site where the person uses outdoor wood glue and tiny foam balls for flotation. The glue waterproofed the foam and held it in place. I just couldn't find the article.

    Hi Shipmates,

    Received the motor today!
    It is a 4074 at 1550kv with water cooling jacket, picture to compare to a 3660 at 3800kv.

    Regards Roy

    Hi Roy, allow me to tell you my opinion.

    To guarantee a buoyancy reserve it is not essential that the spheres are glued together.
    The important thing is that, in the event of a leak in the hull (or in any case if water is entering the hold) they remain in position to carry out their task.
    To do this, they just need to be placed in a closed compartment.
    However, in the event of flooding, even if the spheres cannot leave the boat, water will seep in between them.
    Geometrically the spheres do not have a total occupation of the volume and the space between them is quite conspicuous.
    To understand this, look at the images.
    In the second and third attached images a parallelepiped measuring 36 x 24 x 24 mm is represented.
    So its total volume will be 20736 mm3.
    Let's take into consideration spheres with a radius of 3 mm (diameter 6 mm).
    A maximum of 96 spheres of this diameter can fit inside this parallelepiped.
    A sphere with a diameter of 6 mm has a volume of approximately 113.1 mm3.
    Therefore the volume occupied by all the spheres will be 10858 mm3.
    Well if you make a proportion between the volume of the parallelepiped and the total of the spheres you will realize that this is approximately 52.36%.
    Logically this proportion is always the same, whatever the number of balls taken into consideration and whatever their diameter.
    This means that if water gets between the spheres or if the glue you use is heavier or slightly lighter than the water, you will have reduced (almost halved) the floating effect of the spheres.

    In fact I prefer light material but not in spheres. Compact, square shapes that I can cut out. They will fill all the spaces (not leaving them available for water) and will be stuck together without the need for glue.
    In any case, if you still want to use the spheres, you could put them in various hermetically sealed bags.
    I don't know if I managed to explain myself well with the translation.
    I hope so.

    Hi Roy, this system seems better and safer to me than expanded foam, even if by now you understood what the risks were and how to manage it.
    I hope that the glue you used for the balls is not too heavy otherwise it will greatly limit the floating effect.

    an interesting buoyancy method. You must let us know how it works out. ๐Ÿ˜‰

    That's cool CB90! Reminded me that John Cobb's Crusader was filled with Ping Pong Balls!

    Hi shipmates,

    The Hull is a well designed double stepped hull made of Polycarbonate (The same stuff they made crash helmets from).

    Have reinforced the transom with some epoxy resin.
    Added insulating foam for pipes into the rounded part of the hull.
    Added some hardware to the transom.

    Motors are on order, gave myself a choice of two
    A 3670 1900kv or a 4074 1550kv the latter may be better in theory.

    Regards Roy

    I don't know if you can still get then, but I bought from B&M some what they were selling called swimming snake's I think. They were in the children's toy isles. They were like those polystyrene lagging tubes but not hollow. Also came in different colours. they were a lot longer than those grey lagging pipe ones and would go all the way down the side of the boat.

    Hi Shipmates,

    The Polycarbonate Hull
    the only part I will use.

    The rest will be scraped
    (Equipped with Twin 380 Motors Vector-push design for easy control
    Radio Controller with antenna Wall Battery Charger 7.2v NiCD 1800 mAh NiCD Rechargeable battery Extra Pair of Propellers English Manual
    Length: 32 Inches Battery Type: 7.2V 1800 mAh Transmitter: 3 Channel Motor Type: Twin 380 Charger: Supplied
    Skill Level: Beginner / All Levels Speed: 20 - 25 mph+ Battery Requirements: Vehicle: 7.2V 1800 mAh NiCd Rechargeable Battery (Included) Transmitter๐Ÿ˜Š

    I have stripped out all hardware, filled holes in the transom and affixed polystyrene to the hatch / cabin to make it buoyant, so it will not sink if it falls in the water.

    Regards
    Roy
