Good morning all respected Modelers.. it was my long dream to complete a big craft to my personal collection of RC boats.. and started making big crafts mostly above 3.5 to 4 feet span.. but this one is in to 5 feet length, because big is beautiful.. this one is 100% scratch built, and not used even a piece of plywood or balsa.. when completed the hull became stiffer than balsa hull but weighs half than a same sized balsa or wooden hull.. this craft is not a direct copy of MISTRAL itself.. but i added lots of my personal touch in the craft.. the first one is the elimination of the same second Stearn wheel situated at the top of the cabin.. and this craft is fully equipped with modern electronics include the CBW system.. this allow the captain to operate this craft with his day-today laptop as guidance instrument, navigation in all weather.. and for a luxury craft an open cabin is not a safe.. so added two heavy doors to cabin.. still this craft is not detailed fully.. i will complete those with a little time as now i am tied up in some commissioned model projects.. will add the LCD screens in cabin, and revolving seat for Captain with joy stick.. figures are in que and will complete as i gets time.. so here i starts.. so we will find that how easy to make a big beautiful craft .. this craft is not based on plans.. but i used only 3 views.. and scaled to 5 feet...

i started with 1 inch thick thermocol sheets.. (expanded polystrene)..
laminated with marine glue.. with weights.. you can simply see the size of the block as one floor tile spans 1 foot square each..

block is well dried.. now time for scaling and shaping...

basic sketch for every thing.. include engine noise and audio player..and started shaping..

almost final shaping.. time for treatment..

started tissue works.. all simple inexpensive tissues...

after needed depth of tissue started putty works.. this time i thanking to Mr Vinod for the help of putty scribing, and he taught me a new simple way to get a neat finish with putty without adding ample of weights..

putty work in progress...

by using a panel fan drying proses was fastened..

after the completion of the hull i started making props.. the props made by aluminum sheets from a vessel lid, both designed to rotate each other in phase.. because i know none of any commercial props can beat our own tested hand made props..

the blade angles were attained by a body of a metal torch and fixed on a 4 mm bicycle spoke..

i added two end caps of ball point pens at each tip to stream line the prop hub.. for greater look..
and weather proofing with priming..

now props are ready.. the outer tubes are ball point pen bodies with SS bushes each end..no water leaks and long time of life..fixation on craft..

used two Monster 550 motors ..

props are set an agle because of the easy of fixation.. and to avoid any complicated fittings.. so adding a nozzle is a must.. especially when using twin props rotating each other in phase.. to avoid vortex and power loss at high revs..

shows twin rudder mechanism.. used two carbon fiber tubes attained from a kite kit as i got it as broken.. and two identical servo horns are used to drive each rudder panels via brass rods.. see how simple..

here can see the simple set of twin prop and rudder systems.. nothing is complicated here...

at any angle the panels are uniform.. if not this will act as a brake instead of steering control..

one of the unique feature of this craft is its bow pump.. so this craft can turn in 360 degree from stand still without any main propulsion.. so it is easy to turn.. always.. within her's length.. or half within her's length with reverse.. is a must for big crafts.. easy to control..so, here you can see the prop tube of the thrust pump at bow..

pump motor.. is reworked 12 volt motor for greater torque than RPM.. simple installation with foam board.. and here is the switching.. means, up to a certain degree while turning, the thrust pump will not come in to play and craft will turn with natural rudders.. but when we apply full stick to any direction, the servo arm instantly arms the switches switching on the pump motor in desired direction.. so instant turn at all speeds..

can see the simple wiring and motor mounts..

so, now time to test run.. the first test run with twin RS 550 motors became a great failure.. motors together dropped more than 25 Amps and motors were heating up like heating element of a heater.. instead of propelling the craft.. battery was exhausted within some countable seconds.. so disappointing.. so, turning back to the work table.. and i clearly realized the value of my own works on motor prop combinations.. so, painfully plucked all fittings and made the hull free.. and i realized one more thing that this lighter craft need not two shafts but need one.. the craft weighs about 4.7 Kilograms when complete despite her's sheer size.. and she is not a baby.. but she is bigger to me..

so.. after some painstaking reworks.. added one shaft instead of two.. and it became 1000% success.. and test runs proved so OK.. so atarted working back.. painted hull bottom with PO red..

and after started painting the hull because after super structural works it will be tough to work with.. so, here i started adding my personal touches.. instaed of white i used cram yellow for hull.. and whats a work without our personal touches..?

now priamy coat of paint is complete.. and started working on deck.. used all foam board panels to depict the wooden deck..

nearing completion.. see here how easy to work.. and nothing is used here as expensive or rare.. all handy materials.. hand rails were made of brass rods.. and stangenzes were made of foam board..

railing is completed.. the main mast is taken from an old kit spare of sail boat..
