no , next week the sub wants to make a bath in the aquarium. I am now placing the ruders on the hull. Then we shall see wtyh the weight is. Now the sub is 10 kg inclusive the accu 12V-20Ah. So I have 6 kg left to build further. When he is to heavy, I can put less accu's, that's 1.6 kg I believe that it comes right, it must be under the 16 kg. |

The Tijgerhaai has feel the water. Trimming of the Dutch fleet. The tijgerhaai is 16 kg and above the water. There can be 3.5 kg more when I use foam in the hull. The maintank must be 1 liter an the trimming tanks each 0.3 liter. Now we can build further.

Hi Jan, the tanks are looking great! Very clean job! You should try to wash away this green colour with "Aceton". This worked good for my pipes. Lothar |

Black sunday in Den helder. The space in the tijgerhaai scale 1:50 is to small to put there a pressure tank. So i build one between the hull and the tube of copper pipe, but that is to heavy. So then I must sail with fever battery's 12V/8A in place of 12V/16A So conclusion to little space. So next week we transform it into the old way with a deck in between, so i can use the stuff I already build and I can put 8 kg more into the sub. So Lothar you are right, that its to small for a two tube hull. But its get his air pressure en valves. Pictures over two weeks. Jan Kraak
