    TomKat
    Ripmax Tomkat, an original design built for a 12in passenger, but can run without and will go that bit faster, upgraded to brushless and 2.4 G radio and lipo battery. Originally had a 550 type motor brushed esc, 27mhz radio, and ni-cad battery, main fault of boat is that it has a very poor reverse, as it has been designed with a surface piercing prop, so only effective in forward motion.
    Refurb of Flower Class Corvette
    Found this boat in a junk shop for Β£25, replaced 380 motor with a geared 540, new servo and speed controller, some general repairs and a new paint job. Runs on a old 27mhz RC gear.
    Norfolk Broads Police Boat
    This was a renovation project the idea was to on convert to a Norfolk Broads Police Boat from the 1970's Running on an old 27mhz Acoms radio with brushless motor and ESC.
    Pursuit Boat 7
    In 2019 I started this racing boat but as of yet have not managed to get it to a lake it runs on 14.8v lipo with 3674 High Performance 2650KV Brushless Motor. Please note rudder is hinged so if it hits something it lifts up, to prevent damage.
    (Naval Ship) HMS Sabre, Scimitar-class preceded by Archer-Class
    Please note this is not a scale Model it is a club racing boat (semi scale) and will get many knocks and flips during racing. The trials of this boat went well I remember comments made by members of the Eton park model boat club (Norwich) on how fast and quiet the boat was. There was a problem on sharp turns it ventilated and lost power, I tried various modifications over the next year, but in the end knew the prop was too close to the transom. So July 2020 the boat was stripped back to the basic hull and holes filled, then motor, shaft, servo and rudder were re-positioned. Another trial will then occur, also I have decided to seal the windows in the cabin and fill with polystyrene to make the boat self righting, as last time it flipped over in a race it remained inverted until it blew to the edge of the water. upload 3 photos to add to original 3 2018 Just finish this little boat, need to have its first trial on the water to measure current draw and perhaps modify the prop size. Make sure water cooling works, and the thing steers ok. The Motor 3650 4Poles 3060KV Brushless RC Motor for 1/10 RC Car Boat 1. 4Poles design, high torque and high efficiency.

    (Naval Ship) RAF ASR 1942
    This kit is based on an RAF ASRL Boat and is formed of High Impact Styrene for you to add your own hardware and detail. Kit includes Hull/deck/superstructure/windscreen/clear gun covers/dinghy/boat stand/servo, motor mount and instructions. Approx Length 24in x 7in 1/35th scale. HSL100 Type 2 High Speed Launch 63 feet 21.5 tons 39 Knots 1941 built by The British Power Boat Company and popularly known as the 'Whaleback' as the cabin looks like a whale diving. The craft operating in the North Sea / English Channel. Their armament consisted of any weapon which the crew could find, they started with a single 303 in each ball turret and progressed to twin 303's (Motor: 2860 4050kv) (ESC: China water cooled 60A) (8/10)
    (Fire Boat) RAF Fireboat (vintage) Aero
    Ebay job Β£50 Old Vintage Aero kit 34in Fire boat needing a lot of attention, with delaminating plywood, old glue, old glow-plug engine mounts with electric conversion, and after removing a metal shield I discover an vintage (1970,s Ripmax Bullet 30 Motor the dogs bollocks of electric racing of its time capable of running 24v at 15A. 300W for a brushed motor. Started by revamp rear pit by lowering servo and rudder and building sub deck, storage lockers, tow hook and ladders. Remount the motor with an aluminium mount with custom screw positions. Block windows with 1mm ply. Foam front half of hull to make unsinkable. Make centre decking area. Repair and build up on cabin roofs and walls to centre deck. Rewire add ESC and servo. Remove broken and unusable fittings such as large vents, some missing unable to match again. Problems with old gloss paint crazing the modern spay paints. Build some fittings eg Water cannons, life belts, Build new battery trays, Painting the boat now in progress as of 20/04/2018 Boat has be roughly painted but is not finished, as fittings are now required, added a RC system an gave it a test run. the performance was adequate on 14.4v and great on 17.2v see latter pictures on the pond. the motor did get hot after about half hour of use. the motor is rated at 24v but I think a smaller prop will be required for that voltage. Excellent performance from a brushed motor. Added some stickers and I have now added a 12v fan and ventilation between cabins as the motor required some cooling and was in a sealed compartment. (Motor: Bullet 30) (ESC: 24v 15A Electronize) (9/10)
    (Pleasure Craft) Jet Boat
    Modified from standard 360 motor to a brushless 20mm motor this was my first brushless conversion back in 2013. (Motor: 20mm) (4/10)
    (Racing Boat) WL 915
    WL 915 ready to run Brushless 2.4GHz RTR Electric RC Speed Boat. This RC boat is capable of reaching speeds up to 25MPH and anti-capsizing technology? The flood chamber in this boat causes the boat to struggle to get up on the plane, in the end I filled it with foam, and put in a new rudder offset to the right, it now goes well, and I haven't flipped it yet! Features: β€’Electric Powered β€’Capable Of Up To 25MPH? β€’2.4GHz Transmitter β€’11.1V 1200mAh LiPo Rechargeable Battery β€’Balance Charger Specifications: β€’Length: 17.25 inches β€’Width: 6.8 inches β€’Height: 4.7 inches I will be modifying this little boat as it has a few annoying problems they are: 1. The flood chamber fills quickly and once full hampers the boat in accelerating and getting on the plane. 2. You cannot run the boat slowly as the flood chamber fills 3. The self righting is not 100 percent reliable. 4. Binding is initially difficult Mods a. Replace cabin so boat lies flat when inverted. so able to use rudder extension to steer when upside-down. b. Racing rudder side position out of prop-wash and aids torque effects. c. Fill float chamber with foam so gets on the plane quickly. d. Cut down rudder as too long (95mm) to 65mm. The cabin will be finished and painted properly after testing. On testing the rudder was reduced and performed well once it got going but still have problems getting it up on a plan it feel this could be a balance issue, needs more mass at the stern. (Motor: outrunner) (ESC: unknown) (5/10)
    (Racing Boat) NDQ Modified
    NDQ cheap hull, ripped out radio replaced motors with brushless 2845 2600kv add rudder/ servo, trim tabs and turn fins also added strakes to the underside, foamed the hull to make it unsinkable add radio link radio modified to control both motors 2845 2600kv via SimonK firmware developed for drones brushless escs ( both motors run at same speed) 30A. Boat currently pulls enough to get hot motors on 3s (240W total). (Motor: BL 2845 2600kv) (ESC: 30A gerneric) (9/10)
    (Fire Boat) Grimmershorn II
    The Motor vessel 'Grimmershorn' was built in 1956/57 by Hansa Stahlund Schiffbau GmbH at Koln-Deutz for the Waterways and Shipping Administration at Cuxhaven.Her Daimler-Benz four stroke diesel engine had an output of 500hp. permitting a speed of 11.5 knots. The model hull and deck are vacuum formed ABS, timber work of precision cut ply, 2 full size plan sheets and a construction manual along with a fittings pack complete this kit. Technical Data Scale: 1:20 Length: 1038mm Beam 305mm The Grimmershorn was the second major kit I purchased from a model shop on the outskirts of Harlow in Essex back in the 1980s. The Krik kit is still produced and sold today. My build was a slow and lost enthusiasm so after completing the hull, deck, motor and bow thruster installation I gave the boat to my father in-law who completed the superstructure and sailed the boat for a while, eventually the boat was given back to me when the father in-law moved house. I then repaired the rudder, added a moving radar, a adjustable water cannon and pump also various extra fittings such as a detailed life raft and crane, buoys and captain figure. thus renamed the boat as Grimmershorn II a Search and rescue fire boat. (Motor: 950) (ESC: 15A 24v) (5/10)
    (Racing Boat) Interceptor
    Zoom 1 (Interceptor) Mono boat. Built from a Glassfibre hull, brought on Ebay for Β£35 the hull is a slim mono racing type with a self-righting side cabin it runs a 1400W 14V 2958 4200KV Brushless Motor and 29-S Water Cooling Jacket with additional air cooling fan. I did not want to use a flexi drive as high maintenance and prone to failure so the shaft runs via two universal joint one at each end. the propeller is a 38mm copper alloy The ESC is a 200A and water cooled the twin rudders supply separate water one for the motor and one for the ESC. The rudder are positioned to reduce prop-walk and are hinged to prevent damage if hit a object in the water and ride adjustment. Turn fins and trim tabs for ride adjustment were provided by a spares kit for another boat. also foamed and added an inner sealed hatch, a rubber bump strip and safety loop. The Boat is fast and over-powered used at half throttle, may use a 7.4v lipo instead, the self righting works well. 20th April 2018 while running on 11.1v the boat stopped, no response on retrieval it was found that the manufacturers battery connector had melted and the connection lost see later pictures. the battery was made by FLOUREON and was a 35C with 5500mah capacity the 80A fuse had not blown. (Motor: 2958 watercooled) (ESC: Unknown 200A) (8/10)
    (Naval Ship) PT 109
    PT 109 The famous ww2 PT boat skippered by JF Kennedy (later to be President of the USA) This has be one of my have to have model boats and it was by luck that I found one for sale on a model boat club's web site in 2013, Β£100.00 later and a journey from Cumbria to Yorkshire and back, I had myself a ProBoat PT 109 This was a ready made RTR model when new and is 40in (1m) long, the boat needed some small repairs but after a test run I found that the running gear was noisy and on investigation discovered that both propshaft were bent and had no bearings from new, the couplings were just direct connections. So with great care I replaced both prop-shafts, propellers, coupling for two double Huco's (universal) and the single ESC by two new Aqua speed controllers and both motors with Graupner speed 600's Note I also foamed the front compartments to make it unsinkable in theroy. (Motor: Graupner 600s) (ESC: 2x ) (7/10)
    (Naval Ship) Perkasa Class
    A Malaysian Fast Patrol Boat Perkasa produced by Vosper in1966,she has 3 gas turbines engines and a speed of 54 knots, and diesels for cruising. The model was built in the 1980s but has only recently been fully powered up for planning speed, handle choppy water very well, port and starboard motors are 2x Graupner 600 7.2v and centre motor is a 700 type motor, 3 shafts run 3x 35mm propellers and it has two rudders, the guns are remote controlled (Please note the stern/rear gun is not accurate and is just a copy of the forward gun Bofors 40mm and not the 20mm Oerlikon. Search lights, radar, running lights all work the 3xESCs are a cheap China ones that do the job but need to go to neutral before going in reverse, just use self centring joy sticks on the transmitter. (Motor: 2x 600 + 1x 700 type) (ESC: China) (8/10)
    (Naval Ship) CB90
    Scratch built at 12th scale from pictures and profiles of the original boat, hope to upgrade batteries to 11.1v lipo.

    Hi Shipmates,
    (Need to get this off my chest.)
    Normally I have had good service from the Chinese sellers on Amazon UK
    but in the last 3 months I have had problems with some of these sellers.
    Examples:-

    1, Ordered an item, one month later it is due to arrive, and suddenly get an email from seller saying they are refunding the money (after holding and probably investing it it for a month) making an excuse damage in transit, when you go to reorder they have doubled the price of the item.(Β£24 to Β£56)
    This has happen about 3 times on items such as ESC's and motors and Lipo batteries.

    2, Item arrives but have to pay customs duty (Β£12.40) have to contact Amazon and try to get it reimbursed of the seller in China this has happened twice in the last 3 months. Amazon got it sorted the first time, the second time was today also sent me a 70A esc instead of the 120A I ordered, what a mess.

    Amazon don't have much control over the Chinese sellers so if you get problems you have to depend on the Seller's integrity. Good luck.

    Regards
    Roy

    Hi Doug,
    Any Drawing would be of help, I have collected a few!
    The Serident tubes are under scale by a 1mm in diameter will haver to put plenty of paint on them!
    A picture of an Italeri 1/35 Scale Elco PT 109 Kit by Stuart Hurley also from the 103 web site, its a detail build of the 109, modified from original.

    http://www.pt103.com/Italeri_PT109_Build_Stuart_Hurley_3.htm...

    AFTER SOME RESEARCH OF ORIGINAL PHOTOS I THINK THE PT103 WEB SITE IS CORRECT SEE PIC 3 FROM THE FACTORY AND PIC 7 OF PT105.

    Hi Mark,
    The picture of a motor looks like a decaperm or hectaperm these are high quality motors and very efficient for a DC brushed motor.
    they did two versions of each, a 6V and a 12v,
    with a big prop use the geared end to connect to the shaft.
    I have a 6v Decaperm and it moved a 90cm very heavy boat about 6kg around for over 30 mins at 4mph on a 6v 4ah battery. normally pulls 4 amp underload.

    Nominal voltage 7.2 V
    Operating voltage range 3.6 … 8.4 V
    No-load rpm 18200 min–1
    No-load current drain 2 A
    Current drain at max. efficiency 12 A
    Current drain when stalled 85 A
    Max. efficiency without gearbox 69 %
    Length of case, excl. shaft 57 mm
    Diameter 35.8 mm
    Free shaft length 8.7 mm

    Hi Shipmates,
    Mini update, added some details:-
    1, Two strengthening bars diagonal from spray shields and a petrol filler centre (pic 4)
    2, Drip bars over windows, apart from starboard forward window. Not sure why this is missing,(please enlighten if you know) I think it may be due to the hatch above this window being hinged inboard, pt 103-127. perhaps could be an obstacle to exit? see picture from pt103.com. (pic 5)
    3, Small step to rear turret, and petrol filler. (pic 3)
    4, Brace on top part of roof. (pic 1)

    Hi Doug,
    Thanks for the glue tip, if I have problems I will buy some.
    I have tried to keep the weight down to a minimum, as my back is in a poor way, so it hopefully will be between 5 and 8kg
    Example the torpedo tubes are made from two 'Sterident' tubes (denture cleaning tablets) I have only just started making them.
    When I get time I try to weight it.

    Hi Doug,
    The gun turret ring was a cut out of a fish food container, I have stuck it down with non expanding Gorilla glue, just hope it holds as the plastic is a bit flexible.
    Added a measuring tape, so you can judge scale.
    The turrets were a plumbers joint for 60mm pipe, I think?

    Hi Shipmates,
    Roughly fitted ESC in then add some LEDs to the exhausts' powered by a 3v battery box and switch, 'Holy Smokes Batman', originally wanted to fit them from the inside but the restrictive room meant I could not, so need to block the exhaust holes. I feed them in from the outside and glued them with expanding gorilla glue, nice and bright. Also drilled holes for cooling tubes from the rudders. (not shown)
    Regards Roy

    Hi Shipmates,
    My ESCs come without connectors, my preferred connector for this ESC is a 6.5mm Banana type as the wire are thick, unfortunately the motors were prewired with 4mm connectors which out of laziness I did not want to remove, also a 6.5 would have been too big.
    So the solution was to make an adapter (I know more resistance losses) luckily the 4mm fitted into the 6.5mm's wire socket, so we have a 6.5 female on the ESC connected to a 6.5mm male connected to a 4mm female. (made 6 of these)
    Hey presto!🀞 and one burnt finger do to carelessness while heating the shrink down.

    I know some aspects of the ESC cable lengths are important I think it could be the cable from the battery to the ESC (where the capacitors are situated) has anybody got the lowdown on this.

    Regards
    Roy

    Hi Shipmates,
    And now for a boring but essential part of the build,
    yes 'the boat stand'. I just hate making these, I put a bit more effort into this one, It is designed to flex so will sit on uneven surfaces, eg grass banks etc.
    Cut ends from 11mm waterproof ply, added some foam pads, used rightangle aluminium, for sides , glued with Gorilla glue.
    Not sure if it will need more support!
    Sorry about the crumbs.
    Regards Roy

    Hi Shipmates,
    Martin guessed that it was going to be a Batboat and was right.
    I got fed up with normal boats, so I thought I would do someing that was pure fun, that I could design myself.
    Still lots to do, windscreen, steering wheel, dashboard, water cooling, wire ESCs, Painting and logos.
    Regards
    Roy

    Hi Shipmates,

    β€’ Have taken off trim tabs and increased the angle on the transom pads re-
    affixed so they are clear of the water in their neutral position.
    β€’ Added fixing points for servo mounting board/battery box
    β€’ Foamed front compartment to make the boat unsinkable, also filled gaps
    between seats and cockpit sides.
    β€’ Added ABS top to the compartment hatch to enable me to tape down the
    ABS area without damaging paintwork to provide a water tight seal.

    🀞 After reading an article on using the rooster tail effect to lift the rear of the boat in a similar way to a trim tab. I have designed a deflector plate to hang over the props thus when the rooster effect occurs the force of the water hits the plate (riding surface) and lifts the stern slightly.

    Hi Shipmates,
    Thanks for comments, Like always you don't know how a boat will perform until its on the water, then you realise what you have done wrong or right.
    Its funny that Windermere was mentioned as I live about 30 miles away from it.
    Shame it has a speed limit of 10mph, if anyone need a big lake the one at talking tarn is 65 acres. and there is a model boat club there,
    https://www.facebook.com/groups/CalisleMBC/
    but no shelter close by.
    "Talkin Tarn Country Park lies nine miles east of Carlisle and two mile south of Brampton on the B6413 Castle Carrock road. There is a 65 acre lake set amid 120 acres of farmland and woodland. The tarn is an ideal place for active recreation or a quiet stroll through the mature woodlands."

    Note the servos were dirt cheap from Amazon at Β£1.99

    Hi there Shipmates,
    Added a brace between stingers, I know it will cause drag but its better than the props (40mm) touching under the forces applied to the stingers in turning etc. initially they where only 0.5mm apart the brace holds them at 1mm.
    Put servos in positions. (metal geared digital 20kg)
    Added padding to cockpit seats, centre console under way.
    Added shaping to main compartment hatch (a bit like Beetle wings). filled with foam, so hatch will not sink.

    Regards
    Roy

    Has anyone got one of these motors and can measure the resistance across the terminals, and then compare to the resistance of these ones. may have to move the shaft to try to read all 3 coils.

    Strange these motors should run so hot, are they old, do the brushes
    and commutator need cleaning.

    Hi there shipmates,
    'Nut Screws Washer and bolts', yes there're all in the transom now.
    Had to put the bolts in backwards for the turn fins as the space restrictions inside made it near impossible to use a spanner or box spanner inside the hulls stern.
    Added side panels to the cockpit area. Build in seat started, not shown but reinforced rear access compartment.

    Regards
    Roy

    P.S. the rudders are vertical it's an optical illusion caused by my camera!

    Hi Ron,
    Reading your notes about the boats lack of keel, could this cause stability problems especially with the boat being 30in long, and a beam of 7.5in.
    I assume it will be used as a radio controlled model.
    Are you going to put in a metal keel to keep Centre of gravity low?

    Hi jbkiwi,
    My Father a young lad during ww2 used to collect ammo rounds which he found on the marshes in Essex UK, he had quite a large amount of gunpowder / cordite also magnesium from incendiary bombs, seemingly towards the end of the war the Germans would drop their load over the Marshes and turn back for home.
    Dads collection of stuff (powder) was kept in the kitchen cupboard on a baking tray.
    A story goes that he filled a washing up liquid bottle with the stuff and used a cordite fuse, lit it and panicked and put it in a dustbin
    when the thing exploded it sent the dustbin lid up into the air cutting off the smaller branches of nearby trees that were 40ft high, if you looked up you could see the hole it had cut in the treetops.

    Surprised he didn't kill himself, he later joined the RAF (conscription) as a Armorer for Meteor 8's 50mm canons.

    Roy

    Hi All.
    When I joined PO Telecommunications (BT) in 1979, the external guys used these and heated them up on a Bunsen burner, and used them to solder wires in underground joints, a bit heavy duty for modern electronics, should be good for soldering copper pipe joints.

    Hi there shipmates,
    Due to the propeller shaft spacing of 41 mm apart, I had to make a engine mount, and angled it to a line the two flexi shafts with minimal bending.
    I will not cut the flexi shafts until I fit the two contra rotating propellers, that are on order. 2x 40mm diameter x 18mm pitch.

    Starting on the cockpit area, I lined it with wood and built a seat also from wood, waiting for some bolts before mounting the rest of the hardware to the transom.

    Regards Roy
