    That would figure, I guess...so filling the tank from the middle may give you a level dive, then?

    I had a Dumas Akula ages ago, just before I became ill...horrible thing, never did like it. I sold it in the end, the guy that bought it from me sold it on, I don't know where it is now.

    I'm wondering whether to install some baffles in the flood tank, and alter it to a central fill/empty position. That way the water wouldn't slosh around inside the tank, and I think you'd get a much leveller dive. I don't really know yet, that's something to play about with later.

    Another alternative would be to replace the tank with a length of 60mm diameter tube, fit it exactly in the centre of the boat, and have a bag inside it. May be worth thinking about...

    just a segestion you could fit two tubes at one end one to go to the middle plug the one you don't use I have the tubes at each end I plug the one I don't use at the time with a blanking cap

    Yes, that's another idea...I think I may assemble the tank during the week and play about with a few ideas, see what happens.

    Oh yes, I've used microswitches for years, I prefer them for a pump over an electronic controller any day. I guess it's just what I'm used to, a lot of people use electronic controllers with great success, but I'm old fashioned...I'm told I'm an old fart. I agree!

    I was thinking about what you said about filling the tank since I have 2 filling points connect the 2 with a " t" connector in the middle and fill boath ends at the same time

    I've never used a magnetic switch, if using a box I normally cut a small access hole in the lid for switching on/off.

    Krick Type V11 U-Boat - Page 2 X_craf11

    This is the radio box lid on my X-22, to turn the radio on/off all I did was to unscrew the red cap you can see and use a wooden sick to switch the radio on/off. It was the top of a fizzy drink bottle.

    Cheers Willie...that picture was taken about twenty five years ago. That was a dynamic diving boat, the new one I'm building will be a static dive version.

    There's two or three other ways of getting to your on/off switch, give me a shout if you need any more ideas.

    Richard.

    Hi All

    Is it me but does this not look like the old HFM type 7 ? 

    In the new year will try and post some photos of my HFM 7 along with photos of the wtc that Alf Blake made for me out of an old rain pipe, 

    Steve J and I spent the day with Harvey and Harvey made us a set of moldings each. I got mine for £45.00.

    We had them on the club stand at IFOS 2000, and at the time of my sailing, my wife spotted the Red Arrows and missed me sailing.

    The boat is still sailing to this day.

    As far as I know, Fred, the Krick boat and the old HFM boat are miles apart. I think the Krick is a bigger boat, and the construction is totally different...they are both based on Type V11's, and that's about as close as it gets.

    My hands are not cooperating this morning, so I've reopened the Krick box and had a real close study of it. There's no way I can make it look anything like a Flak boat, so I think I'll just built it as a generic Type V11 and leave it at that.

    I have decided to use a cylinder instead of the radio box though, I've worked out that I can fit a 500mm length of 70mm diameter tube inside it, which is more than enough to install everything in.


    I may use the supplied ballast pump to fill a bladder inside a tube, or I may go for an air system based on the old fashioned Darnell method, but using my small Koge air pump instead of the modified USE steam engine that Darnell used. It's a proven method, and I've used it many times before, so I'm quite happy to use it again.

    As they say in all the best places...watch this space.
