Aerokits 34" Crash Tender
Nice sunny Sunday Sail at Boundary Park so took the Crash Tender for a spin
28XX brushless 11.1v 2200 Lipo 35mm three blade brass prop.
Uses 30 amp cars ESC with small fan.
Tx set to 55% on throttle otherwise it takes off. Rudder throw at 50% for same reason. Switchable to 100% for slow speed manouvers.
Great fun.

Miss Geico 29"
This is the 29" Brushless Miss Geico. Running on two 14.8 volt 5000mAh LiPo batteries. in Herbert Woods Boatyard in Potter Heigham Norfolk. She is pretty quick but do not know her top speed. Turns flat out on full rudder lock. Runs for about 15 to 20 minutes. Would recommend as a great fun boat.

    i know what you mean about speed and i am always trying to get more from my steam boats!!! they are very slow compared with your petrol and brushless jobs but my aim is for more speed .i am working on steam turbines at present which are very inefficient and not that powerful but the intention is eventually for more speed !! you want to try coal fired boiler boats [ i make my own ] . there is much to do pondside what with stoking and water filling and oiling and all and i get loads of fun ..... much more than sailing my old electric crash tender which was fun to build but boring to sail . les breame

    It is surprising just what you can get a Crash Tender to do. They can be very fast and also handle very well on the water. Those Vosper hulls are amazing. That's why they were used for the fire tenders and MTB's etc. But then the Fairey hulls like the Huntsman and Spearfish also handle very well at speed.

"Sweet Sue"
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 ?

    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?

Original Aerokits Solent Lifeboat
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.

    very nice boat and yes it is difficult to video and sail at the same time ! try to get someone else to steer while you video !! using a tripod is best. Les Breame

    Thanks for your feedback.
    I was using a monopod so I could pan and follow the model. I agree the tripod works much better. All my fellow sailors were otherwise engaged unfortunately.

wardrobe
Recreation of a boat built when I was 14/15 55 years ago,used a clockwork gramophone motor with the rudder couples to an eccentric on the spring box to make it sail in a lazy "S".the original lifted in the water but did not plane properly so seeing if 55 years later I have learned anything!.

    That's different, are you going to still use the clockwork motor. How does the rudder work. I see it has a wire from it to inside the boat. Also what is the nipple on the side sponson for?
  • philpjukMaster Seaman
    yes still clockwork,The best improvements have been made by lightening the motor, drilling holes in everything and replacing a side plate with one made of alloy.It is just a nut on the sponson, they are adjustable for incidence.It will now plane on the sponsons "unsticking" the hull.The original was built when I was 13/14,the motor came from the family gramophone when my dad converted it to autochanger/amplifier,the wood came from the woodshed but I was short of plywood and realised the back of my wardrobe was plywood and was hidden behind clothes so when my parents were out I cut the bits I needed from it!,my mates christened it "the wardrobe".Performance is down to propeller choice and is a compromise between speed and runtime.I took it to a boating pond in a nearby town when my wife needed to visit it and a council "jobsworth" told me I was not allowed to sail it,"only yachts and electric boats on here sir"no amount of reasoning would make him change his mind and he escorted me out of the park!.

Creepy
This is Creepy,a springer tug that is 5 yrs old now.He pushes #1200lb pumpkins for the pumpkin regatta along with saving many of the PMPBA club members boats from certain sinking or floating away.I never go to any of the club floats without him.He runs a Harbor freight 550 motor running a Target Hobby 320amp ESC,on a 5000mah 2s lipo battery.The plans can be downloaded free off the internet and takes about a week to build for the experienced builder,Great for the new boat builders to do because its an easy build tug.Simple door skins,some balsa,1/2a running gear from Dumas,1.5 brass prop,2x2 rudder from aluminum,cheap 2channel radio,ESC from Target Hobby.

RAF Target and Towing launch (Kitshack)
My 1st excursion into model boat building about a year ago....steep learning curve!!!

Currently powered by 2 x 480 brushed on 11.1v, both motors independently controlled by 2 ESC but soon to be refitted with 2x 1000KV brushless.

Planes beautifully and with twin rudders turns on a sixpence!

    That's an excellent running time for a fast model.
    😀
    It gives a great indication of what can be achieved with brushless motors.,

    I'll have to try brushless motors in some of my fast scale boats. I only have one brushless powered model at present, this being the Proboat Blackjack 29 fast electric.

    That's a great model. Do you have any photos or videos of the boat at speed?

Wahine
Wahine was a car passenger ferry of the Union Steamship Co. of New Zealand, and completed by Fairfields in 1966. She was lost in a major storm in the Cook Strait in 1968 with the death of 53 people. The model is substantially scratch-built with some fittings purchased. it is driven by two Graupner Speed 500 motors powered from two 6.6V 3200mAh LiFe batteries. it is fitted with twin stern and a single bow rudders, and bow and stern thrusters as on the original. The smoke effect is provided by a Steam Master Unit.

This film was taken on our home lake at Needham Market . Originally an I.C powered boat I have converted to single brushless motor on a direct drive 48mm prop , single rudder . Powered by 2*5000mah 4 cell lipos . As you can see I am very pleased with its performance . 😎

    These are originally an I.C kit 1/6 scale , there is a company in Germany still making them believe they are called MHZ. I think I've scene them in 1/8 and 1/35 scale too . Also other builders have used water jet drives on films I've watched . This one is running on brushless motor normal prop and direct drive as all my boats have so far . Keeps the cost of spare parts down %uD83D%uDE0E%uD83D%uDC4D

    😊 I like the model and the motor. Fondly remember Taycol motors in the 1960s. I had an Asteroid in a Veron Viceroy and cost a fortune in dry batteries though it was very enjoyable,

    I remember the Basset Lowke ready to sail boats which I later found that the same models had been produced in the 1930s. Both models were 39 inches long and one of them ,Streamlinia was steam powered launch with a funnel to the aft of the main cabin and the other was a similar sized launch with a different superstructure and electric power.

    I must say that Margaret is a masterpiece with traditional quality and detail and a power unit to match.

    Does anyone know if Basset Lowke are still in business?

    The last time I saw their name advertised was over 10 years ago when I saw a couple of new O gauge steam locomotives in a model shop
