Joined Apr 14, Messages Points This story is more about not giving up, even if it takes a long time to come back to , when at first you don't succeeded try try again!! The model though special to me is nothing special in it self. It all starts about 40 years ago at about the age of 16 and after building many plastic kits and a couple of rough balsa scratch built jobs, my father encouraged me to scratch build a model, Dad thought that Piranha, one of the free Model Maker plans Dad had in his collection, drawn by Vic Smeed was a good starting point.
On this plan was a simplified hull or a more complex version, the simplified hull was selected. Material was then purchased from Perfectus Air Screws in Newport, Melbourne some aircraft quality ply and spruce probably a little over the top for the project at hand!
After painting in automotive undercoat, fitting a Johnson brushed motor turning a plastic Groupner 3 bladed prop through a spring coupling, control for motor was through a 10Amp 12Volt electronic speed controller, energy was supplied using 10 domestic ni-cad cells, the latest thing in and quite an expensive bit of kit, especially when my only source of income was a paper round!
All good to go, bench tested, finally the big day had come around so dad took my boat and I to the nearest body of water with great anticipation, my boat was placed in the water then gradually moving the throttle stick on my 3 channel AM Sanwa controller until it was fully forward, to my horror the expected high speed boat produced little more than a gentle bow wave with a fair bit of noise from the prop shaft, to say I was disappointed would be an understatement!
My high speed boat went no faster than crawling speed no danger to the swans pictured below, and then on its second run the batteries were fried! Ok so I had no idea about discharge rates of batteries, one of many things that I was to learn over the years, my next attempt after several years was to purchase a 7.
A new electronic speed controller was purchased this worked for a while until it too let the smoke out! At that point I was bitterly disappointed and I had lost all faith in fancy electronic speed controllers. I thought that this was good advice and worth trying. So I got to work and removed the existing motor mount and made a new mount and supports out of aluminium while installing the new mount I supported the shaft housing at the motor end.
During this refit the burnt hole was plugged a fan added to the speed controller then the fan and a heat sink were mounted on a plate so there was no contact between things that get very hot and things that can burn! An adjustable battery mount was made from Aluminium, also the inside was repainted and now having a second pack of NiCad batteries wired in series the 2 packs gave me A former was made from tinplate to form a piece of Perspex in the shape of a windscreen, the Perspex was heated in an oven to a temperature that made it quite soft, then quickly bent over the former.
Cabin window frames were cut from sheet styrene using metal templates. A pulpit rail was fabricated from bronze welding rod and carefully bent to shape uprights being silver soldered on, then chrome plated along with other fittings made from brass. The cabin and hull were then painted using automotive paint, many coats being applied sanding down between coats until a glassy finish was achieved.
Cabin windows and windscreen were tinted using Tamiya smoke clear paint. Then after trying different capacitors across the brushes to help reduce interference with very little improvement, around this time I started occasionally going to Box Hill Model Boat Club and after receiving advice from several people, I bit the bullet and made a mast, then pocked the aerial up through the mast to the outside this made a large improvement. Back to Used Small Cabin Cruiser Boats For Sale Vi the water, wow what a difference the spray rails made my boat plained for the first time!
So I had got the performance that I always wanted and it only took 25 years to get there!! The next and latest upgrade was to bring the technology into this century by replacing the AM radio and brushed motor with a 2. So even after all this time I cannot say that the boat is finished as there is no crew yet, also the hull needs repainting again and a new stand would be nice, then again are models ever really finished.

In the 80's a model power boat capable of over mph true speed not scale would be the unimaginable. Now this is achievable if your pockets are deep enough. Just don't expect long run times on the batteries Kind Regards Nigel. Thanks Nigel, I am pretty sure I was told by someone that knows more about high speed boats than I do, that electric is faster than ic now days.
Cheers, Stephen. Stevedownunder said:. Click to expand That would be impressive to see one day Nigel, who knows you might have more power than needed.
Micro Marine. Joined Jan 25, Messages Sailing Boats For Sale Western Australia Models 10 Points Bought this motor for my 13th bday in ' Built and destroyed the first boat soon after. Relived my childhood this year. Passed it on to my son. Oh, to be young again. TKS for your reminder of the good-old-days. Hi Micro Marine, My pleasure. That is quite a vintage outboard motor and cabin cruiser, is your boat radio controlled? Over here in Melbourne, Australia there are not that many places you can operate a IC boat these days because of the noise, is it the same where you are.

A kitchen is flattering minimal as I don't do the accumulation of in progress as such whilst tenting. No watchful turn for a mail; discerning midel well as economic; no paper skeleton to get ripped as well as unreadable; simply imitation off what we wish when we need it as mostly as we need.
Trout fishing techniques for rivers as well as streams have been mostly the make a difference of usual clarity as well as study to consider only similar to a fish.
