Title: its my FAST GUN BOAT..FT 12..
Post by: roopeshkrishna on January 21, 2012, 09:54:09 AM
Good morning all Friends..Colleagues..Modelers..
what is the recipie for a good looking and stunningly performing craft..? yes..buy a kit of laser cut..read and study instructions ..follow instructions..and finish..sure, but imagine that we sees a craft, while driving bay, and yes an extra ordinary one..yes want to make it..so..?  serches for old scraped parts, of wood, and all other..start, by looking in to plan, as it down loaded from net..in request..hard labour..for weeks some times it will goes to months..heavy cost..and no idea about the stabilty..so, we adds lots of led weights to make stable her..result..poor performance..or high performance at high costs..
                But, realize the thing, that we can make any craft in to any size, and any type..with thermocol..(expanded Polystrene)..and that we do not need any money for the materials...!! usually i collect lots of thermocol sheets from, nearest town, as this town is Governed by Central Gov, is under Union Teritory, is Mahe, and the tax here is too low..so ample of purchases happens here a day..most of the refrigerator and TV sellers drops their packages in dump, but now they keeps all thermocol packages for me...and all they are happy that their scraps are cleanned automatically..but me..its all treasures..loads of basic materials...in various grades..yes..and thinking again..and thanking again to God that for the oppertunity..
               And i realizes, many modelers stay away from modelmaking, because of the high cost..but look once here..its too easy and too inexpensive to build a craft..scaled..semiscaled..war machine..cruiser..big ships..patrol..aircrafts..longs....or purely from imagination...
all we know, art is a divine matter..its all a Gift from God..and the art is a medicine for human being..i have a person here, was my class mate from school..and beacme a drunkad..was kicked out even from the de addiction centre..i always sees him as i goes to canal side for R\C boating..basically he is also an artist..after metriculation he went to fine arts college, and i to poly..and after few days he came to me, just to look the crafts in water..and now he stopped drinking and joined us..with modelling..now he is also started making models..and taking medicines to eliminate the withdrawel symptoms..i am thanking god, as he is an excellent painter..now, around the clock..he is with boating...see the amazing power of art..!!..

so if the art is the real gift..think about the model making..!!!  when i drops my cheek on to the procecium arch, of my dioramas..with lights on..i feels it as real..a magical world..amazig experiences..so making a model is far advaced than drawing a picture of same..so..? yes..we must make models..up to our own..non stop..creations..and yes..making..so, it came here and following..so..? yes here is my new Fast Gun Boat..is born..
i Took 6 days to complete this craft, along with 7 others..still happy because she is a beautifully stunning one...from last 5 years, i completed lots of PT boats in various scales..Elco..Huggins..and many..some of them carried by my Friends..and some "handled" by my little son Kundoos...the bigger scale was 1:12..so repeating the same is a waste..so i decided to make one my own that matches the scale of usually used crafts..1:28th..
so as usual, i started with thermocol..after test runs i followed the work...

she spans in to 22 inches and beamed to 7 inches..in to a shallow V..with ridges to lift her..

all super structures are papers...
the craft is purely from my imagination, and not a copy..and accepted many aspects from many machines..for an example, the cabin crew was taken from the inspired locomotive shunter, that i saw from Olavakode Junc:...

Post by: roopeshkrishna on January 21, 2012, 10:20:25 AM
i told you all..the crew cabin is inspired from a loco shunter..and in my imagination, this craft is a mixture of vintage and moders aspects..the crew cabin makes a nostalgia in mind with is vintage look...
while the total appeareance of the craft is modern..

she is controlled by a micro servo, one is reworked for greater torque..


Title: Re: its my FAST GUN BOAT..FT 12..
Post by: roopeshkrishna on January 21, 2012, 10:44:59 AM
all detailing is carried out by..yes as usual by paper..later seasoned..

the cannon barrels are from ear buds..


Title: Re: its my FAST GUN BOAT..FT 12..
Post by: roopeshkrishna on January 21, 2012, 10:49:57 AM
she is equipped with two main cannons one in nose and one in astern..the bow gun is from my imagination, is a heavy A/P gun, capable of AAA.
while the astern cannon pod conceals two cannons, one H/V and one A/P along with AAA capability..

i painted her in glazing silver, is a color one amplifies as it gleams in sunlight..a aggressive effect to a gun boat...

the gas tank was made out of body of a sketch pen, and its two ends were capped with PU putty, and later turned on a drill..

Post by: roopeshkrishna on January 21, 2012, 11:11:00 AM
now she is an RTR....from "O" to RTR..in just 6 days..see how simple and easy to make one craft...!!!

powered by a 4 channel radio, in MHz, to avoid a huge heavy antenna in craft, i used a hand made PLUC propagator, along with th TX antenna, and used a PLUC Flange in craft..it eliminates the need of a cumbersome antenna..and gives me a longest range possible..

see how stunning she is...


Title: Re: its my FAST GUN BOAT..FT 12..
Post by: roopeshkrishna on January 21, 2012, 11:12:24 AM
in any angle she is aggressive...  (:|~ :thumbsup:

oye..Sir..at your service Capt:....


Title: Re: its my FAST GUN BOAT..FT 12..
Post by: roopeshkrishna on January 21, 2012, 11:25:23 AM
and see how fast she is...

i fixed a head lock gyro, from a scraped helicopter, and its comparator out put is chosen to reduce the motor RPM, when a turn signal is applied..so you can see the stability of the craft even at high speeds, in waving water, while turns in a perfect angles because of this..i reprogrammed the ESC accordingly, while altering the output mode of the gyro..it worked..and can see in the video, as it stable as a razor blade...


Title: Re: its my FAST GUN BOAT..FT 12..
Post by: roopeshkrishna on January 21, 2012, 11:30:55 AM
and i told you, it is not feasible to add goodies from  WW2..era..this is 2012...so my craft is named as FT 12..means my First Pt boat of the year 2012..  :) :thumbsup:
so she must be modern in all aspects..so a crew protection method is adopted here as we see in "AARDWARKS" cockpits, as a jettison able crew cabin...is operated by the crew, in an emergency evacuation, by a lever..so the entire cabin will jettisoned in to sea..and this crew cabin is equipped with an air fill able bag, forms in to a boat..so, still she will be still equipped with cannon and rocket launchers..a second show...enemy..bad guys..run...

Post by: roopeshkrishna on January 21, 2012, 11:41:07 AM
and also post an even more high speed video, when i get any of my Friends to shoot the video..alone with one hand it is almost impossible to control her..she is such fast...all shown videos are at 1/4 throttle...


Title: Re: its my FAST GUN BOAT..FT 12..
Post by: Swapnil on January 21, 2012, 11:47:44 AM
That was 1/4 throttle??? :o  :bow:  :hatsoff:
Jeez the acclereration of this beauty is exhilarating! Another breathtaking model Roopesh sir!  :salute:
And the gun sound is so realistic!
Truly fantastic built!  {:)}  {:)}  {:)}

As usual a very neat, clean, fast build! Not only do you build them quickly, your craftsmanship is also impeccable. Fantastic!!! {:)} {:)} {:)} {:)} {:)}

Just didn't understand the part of th 'pluc propagator / pluc flange'. Please post some pictures on this. Also may I request you to post some photographs of your PT Boats? I am sure I could learn a lot from your builds as I plan on making a bigger PT Boat someday.

Regards.

Post by: roopeshkrishna on January 21, 2012, 11:50:57 AM
Swapnil..a million thanks for the inspiration..and yes was less than 1/4 throttle..i cant manage her alone, while holding camera in one hand, and tx in other hand..and she is powered by a 2600 RPM, 275 watts ECM, connected to a reworked ESC..with fast timing to save battery..will add a faster chase later..thank you..

Good morning VC Sir, thanks for the grace..and the PLUC is a method, of radio propagation, by digitization the analog radio signal..i learned from my working experiences, with professional radio sets..its simply known as Phase Lock Loop synthesizing Control..with this method of radio propagation, the radio signal  will transmitted through the ground as possible as maximum, just like the after shock wave of a atomic bomb..so can avoid a cumbersome antennas even to a longer distances..but it will take some extra PCB s attached to the TX and RX, as propagator, and integrator...


Title: Re: its my FAST GUN BOAT..FT 12..
Post by: roopeshkrishna on January 21, 2012, 12:02:27 PM
and sure will post some good photographs of my early finished PT boats, but has to brush it out once as all are much old and left in the scrap place of my grand home..the biggest scale was 3.7 feet of Elco..in green cammou..will add later..its a sad aspect to me that after completion, i do not have a place to keep models..my home is a self built small one..so i leaves my model after making to my grand home..still many are there..and here no on is interested in modeling..except a few..if i was some where with you all..it will be a festival..anyhow, i am inspired with your PT boat much..so willing to make one..think so..and from your works i am too happy that thinking about your dedication and effort in model making..excellent craftsmanship..and amazing detailing..so inspiring sir..and i remember one of the PT boat, with a Oval cabin, and a glazed gun pods..it looks aggressive..will post the pictures as i get time...and clean it all...

Wow, PLUC sounds amazing! Hope you share it (in detail!) with us! :)

sure swapnil..will post it later..any one can follow those aspects as radio is an amazing subject to follow..i got these experiences from making my HAM radio equipments..its all easy..
