All respected Friends.. i consider this model as "The Model of the Year 2012".. because i likes her much.. in look and performance.. it was my long dream to realize a POLICE CRUISER to my collection.. now she is a stunning performer and head turner..
now again i am starting from "0".. and this one is based on my imagination.. this one is fully constructed with foam board alone.. she spans in to 27 inches.. 7 inches beam extreme.. with all needed specs like flasing beacons and siren.. gunsound.. etc.. starts on bare foam board..

you can see how easy to make a boat from foam board..

each and every part are from foam board.. place it.. and glue it..

now the hull is complete.. and fillis the gaps with PU putty..

sealing inside with NC putty.. diluted with NC thinner.. or can also use PS grey..

it is so easy to make hulls from foam boards.. its fun and excitement..
and the prop and drive train..

here i am using a reworked motor, and need water cooling.. so adding a copper scoop just after the prop..

can see the inlet from inside.. and the drive shaft.. scoop in detail..

motor mounting and cooling line attachments.. cooling jacket is made of aluminum C channel..

showing in more detail..once water cooled.. nothing to worry.. you can also use the same line to cool the ESC also.. but need to add a water cooling jacket to it..

and the exhaust tube.. always need to keep a little up, to avoid clogging.. now tested.. time for further buildups..

as she is designed for fast missions.. a low profile is preffered.. and with an angular face to cut down the drag..

beacon beam.. and primed.. with PS grey.. more thin coats.. more life and stiffness..

a Police Cruiser must look stunning.. so an extra ordinary paint scheme is needed.. careful masking  and spraying is needed..

all stickers were made of A4 paper from laser printer.. worked on Photoshop..

decals are over coated.. within that time have to wire Police Siren circuit.. the siren circuit is based on NE 555 timer integrated chip, as two numbers to achieve the wailing effect.. here we need some handful of components to make it, costing about Rs 50/- including a little speaker..

here i am using a piece of thick paper as PCB.. later sealed with wax.. to water proof..

back side..
and beacons.. everything is made from foam board..

the top cover was made of acrylic sheet.. and masked.. painted..

checkout time.. i used blue L E D s as i saw a craft in a documentry..

on the boat.. wiring is tricky..

now almost complete.. see how simple she is.. but stunning same while.. the excitement comes from lightings.. especially at night.. so, lights on..

more angles..

life raft from PVC pipe and paper..

the figure was taken from a Dragon figure set of 1:35th scale.. matching..
and radome is a glue cap..

now she is ready for missions.. this one is finished with PU paint and PU after clear coat.. for long life and reduced drag..

with two 1800 mA/H LiPoly and one 700 mA/H LiPoly she weighs about 1100 grams..
just before action..

in water.. various angles..

she is stunning from any angle..

the machine gun was taken from my spare box.. from a tank kit..

beautiful .... great job!!

and at night.. see once again.. making boats with foam board is easy.. can make any type and any size.. more on work..
action video follows.. cant upload from home.. will cond:

thank you Raj.. Happy New Year..

here is the cool actions.. no 1...

day time patrolling..

many modelers asking for the circuit for the light effects and siren.. here is the construction video.. circuit follows..

Nice build!! Is that PU paint? Where can I get it from??

Last, PU means Polyurethane based paints.. it will be lighter and gives an excellent finish with any machine.. these type of paints are used in automobile industry.. you can buy PU based paints from any car paint dealers from 50 ml to 5 liters as needed.. but, if you are a beginner it is better to spray the NC based paints.. because NC based paints dries instantly when sprayed.. so never drips.. but PU paint will take a little time to dry, and if you are not an expert, will drip.. but gives an excellent finish, and unimaginable colour shades.. 

What do you use to apply the colour?

he uses a compressor and spray gun...

exactly... we cant brush those paints as it all dries much faster.. a handy compressor unit mayhelpful.. 

roopeshetta why are you keeping those ranthal in your table? for working when powercut? 
 

that is roopeshjis version of the ranthal...... its an electronic ranthal...

sure.. the lantern is based on solar panel.. for recharging.. or can by exercising on a cycle..
