Hi Joe,this u-boot was my first attempt,one, because i got it cheap,and two because i thought it wasa full static diver,well as you will have found out,it is,nt,according to the instruction manual,when you,re setting it up to determine the waterline,the stern of the boat should be approx 15mm out of the water,or there abouts when you flood the "tank" the boat will only partially submerge,it will not go down to cover the tower,as the volume of water that the "tank" holds is,nt heavy enough,it was, and anyway if it did go downto cover the tower,there,sa fair chance that the hull would start to implode as the bracing inside is inadequate,but apart from this,its a nice boat,and if you can live with the Almost Static dive,then it ok,
wasyl,also known as Wullie,its easier to pronounce,
