all respected Modelers.. this is my another humble effort to realize one of the classic craft of WW2.. German Schnellboot.. this craft is basically designed on a private yacht.. it is evident in it's structure.. not much in to history, but in to modeling.. these types boats are avilable in kit forms, but much expensive.. and at beginning my intention to make her in to 1 meter in length, but just like my Mistral yacht, it will pose the storage problem.. so, i decided to finish her in to 30 inches, ( 2.5 feet), in length, as i can integrate her with my other PT Boats.. here i am starting from "0", as there is no down loaded plan.. but the entire scaling is done with orthographic projection, (3 view), converted in to 5 portions, each represents 6 inches.. so it is easy to convert in to desired scale.. here i never used any expensive tools, but some handtools, and a driller.. total cost of this craft from "0" to water is Rs 300/- and at beginning i was planned to control her with a toy radio based on RX and TX 2B, converted to drive a brushless and hobby servo.. but because of the narrow hull, i have to reduce weight as minimum as possible.. so, back to professional radio..

the entire structre is by 3 mm foam board.. nothing else is used, but a little paper..

the distinctive shape of the hull is too evident from any angle..
