Good after noon all respected Modelers..
here, is one of my humble effort to realize the ever potent and classic war machine of WW2.. the British Vosper Perkasa.. as it is hard to explain the history here about this craft, anyone can Google it once.. this craft was driven by three gas turbo shaft engines, in mission, and diesel engines were used to maneur.. so we can simply imagine the potential of this machine.. so, she must be fast.. and became one of the greatest machine in my collection..
this time also, there is no plans to download, but entire scaling is done by orthographic projection, (3 View), and scaled to 30 inches, as my all PT boats are designed in this scale.. a great combination RCying.. this one is 100 % scratch built, except the motor and simple servos..

here i starts from big "0" from my work table.. here i prooves once again, we do not need any extra ordinary tools to make an outstanding,practical  craft.. here my tools are a heavy duty art knife, a point iron, nose plier, and some hand tools.. 
here we are.. after proper sketching, template is made on a drawing paper.. then on foam board.. this one is fully made of foam board of 3 mm..
as we are scratch builders there is no restrictions.. adding the bulkheads, up to me needs, while keeping all aspects for internal machines..

one of the easy aspect with working foam board is easyness.. to me, when compared, foam board, (styroflex) stands just second to thermocole..( expanded polystrene).. within an hour the hull is on the mark..

with keeping all experience in mind, i delibrately done some needed changes on hull from original.. why..? yes because this one is not designed and crafted for keeping on bookshelf.. instead this one is for great RCying.. practical.. not a show piece.. so, some minor reshaping is a must..

now hull is ready.. time to fix motor..
the motor cooling jacket is made of aluminum C channel, and here i used an immensely powerful motor.. no compromise..

drive, driven tubes are from sketch pen body and bicycle spokes...placed at an angle, with ease..

the entire gaps were sealed with PS grey.. it adds extreme stiffness with some elasticity..

time to fix motor.. look how simple all.. the cooling tubes are installed..you can also see the rudder servo assy..

cooling system in detail.. we can use same motor cooling line to cool ESC.. used copper tubes as it is inexpensive and never rusts..

prop is made of aluminum sheet of a kitchen lid.. the scoop to cool motor is copper tube.. rudder panel is foam board..

now everything in schedule.. now time to build super structure.. template with paper.. a simple dry run, as the shape of the super structure is complicated.. here 90 % of the super structure is drawing paper.. and foam board..

started working.. later waterproofed..

progress..

for most of the modelers the extra ordinary shape is a tough job.. but here i shows you all how easy to follow..

see here.. the making of curves.. we can make any shape in to any size.. with a song at lips.. not a torturous activity..

completed.. and in place..

time to add the tail..

adding the exhaust assy of diesel engines.. all sketch pen body..
and priming..with PS Grey.. not PSL Grey..

some rechecking is a must, to follow the scale.. dry tests..

making sure every thing is ok..
the mast is made od an old ball point refiller..

more priming and adding the radar mast..

everything is ok..
Torpedos.. the torpedos are made of some glue caps, pvc pipes and caps from super glue..

all glued togather..
the vane assy was made of same pvc pipe..

priming and initial painting..

torpedo holders are made of foam board..

dry run.. on positions..
