Video of the first start-up and test of "Sweet Sue" in dry dock. All went well ! Had two sails on water since.I built this vessel from scratch using a pre made clinker fibreglass hull purchased from Mini Steam Australia. The engine is an oscillating twin cylinder and the boiler is a 3" Centre Flue Gas Fired Vertical Boiler from "Miniature Steam". The gas tank is a 1-1/2" vertical refillable GasTank also from Miniature Steam Pty. Australia. The vessel is radio controlled with the skipper appearing to control the rudder. It has a smoke generator and a rc controlled steam whistle.
This boiler runs at around 60psi ! do you think that is a little high ? I was a little concerned by the amount of steam that is being generated as you may have noticed in the video. I can adjust the intensity of the flame inside the boiler so that a lower head of steam is generated, what do you think ? Kevin
Hi Kevin Yes that's what I do. I am always amazed at the power the oscillator generates and once rotating very little steam is required to maintain speed. Then again it's not for windy or rough conditions. I would try gradually reducing the pressure until the engine show signs of stopping and then increase by a couple of psi to ensure safe running. You do not need to run the boiler at its max rated pressure when the escape valve will be opening just at a level that replaces what the engine uses. Can we have another video with the steam whistle sounding? Dave

Original Aerokits Solent Lifeboat - Posted: 1 year ago by Dave M
Decided to sail the Solent so took some video to share. Uses 2 Bhuler 12v brushed motors with 4 bladed 45mm PropShop props and 12v 12AHr SLA. Twin Electronize ESCs. Radio is Futaba 6Ex but I will probably change to the Taranis so I can get better control using some bespoke Tx settings to co-ordinate the props and rudder. Lifeboat crewe had been on a night out so not quite vertical. Aplogies for the shaky video, it's difficult to sail and video at the same time.
Looking for a new project i decided to try to make an outboard steam launch. The engine and drive took a while to work out but in the end it all came together well. The boat travels at a nice speed fueled by tablets for lightness as the boiler and engine are quite heavy for the boat size which is about 22"long. There is a brief glimpse of my paddle steamer that i also made. Pictures taken at TILFORD rural life museum Farnham. Next show is Easter Saturday Les Breame
The tablets are the same ones used in all MAMOD toys after they stopped using meths.Get them from DREAM STEAM under name MSS Mamod Solid Fuel Tablets. They are not liked by many as they are quite toxic in confined spaces so dont use them indoors!!! For small boats they are great as they weigh nothing and give good heat. Les Breame
Hull is about 36" long and from ORION Mouldings[i think !!] Its quite nice and shows all the rivets in good detail. We are at present making a Puffer 54" long and i am going to make the hull from soldered tinplate[ i hope !!! ] Les Breame
I acquired this boat part built some months ago through Dave M. I have not put too much scale in detail but I am quite pleased with the overall finish. It is powered by two brushless 1250KV out runners and in the first sea trials I used 12v lead acid batteries. (That video was posted a few weeks ago - mdlbt.com/26793). This video shows its second sea trial after I was persuaded to use lipos. The difference in performance is very pleasing. Thank you Dave M for your help and advice during the build.
Thank you for your compliments. This is in fact my second Perkasa. I built the first one about 40 years ago (see photo), before the introduction of the GRP hull. Losing interest in the hobby some years later, I sold the boat and have lived to regret it. (I was also the proud owner of a 37" Aerokits Crash Tender powered by a Frog 2.49cc diesel. That went the same way!) The first boat was quite lively powered by a Merco 61 i/c engine. No pictures of either I'm afraid. Hindsight is a wonderful thing. Steve
