    Club racer v2 Economy version 'Fire wood'
    Reused running gear from my old club race to insert into new hull. The build has been quite quick using 9cm wide planks and gorilla glue, there are no real plans, but as per the rules of the club, the boat should be semi scale military or pleasure boat.

    I have three of these boats built them up from spares, brought on Amazon. All now have the original motors, that run on 14.4v, in all three boats The deep v , small size and heavy boat, makes this a power hungry boat.

    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.

    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. Put in water in last days of September 2022, generally OK, but cut out on full power , I think the battery has had it, brought another to retest.

    (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. The overall efficiency exceed 90 percent. 2. Low heat production, long lifetime, strong overload protection and it can function 95% of its features without any heat sink appliance. 3. High quality materials adopted: high intense aluminium alloy anodizing shell , front and back cover , high-performance temperature-resistant magnetic steel and imported high-speed bearing. Specifications: Model: XTI-3650/4.5D Dimension: 50 * 36mm KV(RPM/V): 3060KV Poles: 4 Max Power: 1300W Max Voltage: 19V Max Amps: 68A Shaft Diameter: 3.2mm Shaft Length: 15mm Connector: 5.0mm Banana Connector. The Real Boat Builders: Halmatic Operators:  Royal Navy Preceded by: Archer class In commission: 2003 – Active: 2 General characteristics Type: Patrol boat Displacement: 24 tonnes (24 long tons) Length: 16 m (52 ft 6 in) Beam: 3.1 m (10 ft 2 in) Draught: 1.2 m (3 ft 11 in) Propulsion: 2 × MAN 2480LXE diesels, 2 shafts Speed: 32 knots (37 mph; 59 km/h) Range: 260 nm (480 km) at 19 kn (35 km/h) Complement: 5 (1 officer, 4 ratings) Sensors and processing systems: Racal-Decca Bridge-master 360, I band navigation radar Armament: 2 × General purpose machine guns (stern-mounted) (ESC: China 60A) (5/10)

    (Fire Boat) RAF Fireboat (vintage) Aero
    Now sold to a man in Kendal in 2021. Ebay job £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)

    (Racing Boat) WL 915
    Now sold in 2021. 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: •Electric Powered •Capable Of Up To 25MPH? •2.4GHz Transmitter •11.1V 1200mAh LiPo Rechargeable Battery •Balance Charger Specifications: •Length: 17.25 inches •Width: 6.8 inches •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.

    (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 I 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 £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, £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 theory. (Motor: Graupner 600s) (ESC: 2x ) 2020 update, removed Aqua speed controllers as they went full throttle if they lost RC signal, replaced with Mtroniks 25A jobs (7/10).

    NQD PX-16
    Hi Shipmates, After many years I finally found one at a good price £20 plus £10 p&p on good old Ebay. I have a load of hardware sitting around, motors rudders etc. So I decided to play about with this boat. Generally it is considered a waste of time and money to do anything with these boats. So I don't expect any 'Likes' on this project, its a bit of a daft thing to do. Information about 32in long twin stepped catamaran hull, beam 9.25 inches, thin ABS plastic. First stage. Unpack and check, strip out all of the hardware, generally unscrew components, most difficult thing was removing the propeller shafts. Second stage wash hull with warm soapy water (in the Bath) and remove stickers.

    Watercat M12 (Jurmo Class) landing craft
    Decided to have a go at building a Watercat M12 as I have recently brought a couple of 28mm jet drives, yet to arrive! and wanted a craft to fit them in. The model will be semi- scale and I intend to modify the stern's deadrise to ensure both jet intakes keep in the water when turning a deep v stern may cause ventilation on turns. upscaled the plans available to make a craft around 35.5in (90cm).

    Scimitar-class patrol vessel
    Two vessel in it class (1) HMS Scimitar (2) HMS Sabre Launched: December 1992 Displacement: 24,000 kg Builder: Portsmouth Armament: 2 × General purpose machine guns (stern-mounted) Complement: 7 (1 officer, 6 ratings) Gibraltar Squadron's two Scimitar-class boats are the smallest commissioned vessels in the Royal Navy. This build was to produce a fun semi scale racing boat, I have always liked the Archer class boats cabin design. So after finding a suitable hull, an old 'Models by Design' GRP moulding I was away with the rest of the build. Striped out all old fittings and remnants removed excess glue. Added strakes to the hull to add lift for planning and control. Produced a semi scale deck and cabin from light ply. Thanks for your interest Roy

    Skinned the frames added deck and splash rail also started on cabin and superstructure, added rudder and installed twin brushed Graupner 600 motors via Graupner style direct couplings. Motor mounting system through a bulkhead gives extra support to motors which mount on to end of the shafts. currently adding a rudder servo mount, as rudder is a close copy of the real boat's and still functional.

The boat was originally built in Sweden a class of fast military assault craft originally developed for the Swedish Navy by Dockstavarvet Speed: 40 knots (74 km/h) Draught: 0.8 m (2 ft 7 in) Length: 15.9 m (52 ft) Overall; 14.9 (48') Complement: 3 (two officers and one engineer); Up to 21 amphibious troops with full equipment Armament: 3 × Browning M2HB machine guns; 1 × Mk 19 grenade launcher; 4 naval mines or 6 depth charges . The Model I was attracted to this boat due to its great performance and maneuverability, this was mainly due to the use of twin water jets as the main propulsion, this is a trade off with efficiency. So my start point was to collect as much information as possible about the boat this involved collecting pictures and profiles of the craft from various sources. http://www.dockstavarvet.se/products/combat-and-patrol-boats/combat-boat-90-h/specification/ Eventually I found some plans of sort :- http://laurell.today/boats/combat/plans.html My Dad was a boat builder in the days of wooden yachts, and had showed me how to make plans and frames from a line drawing. I went about this first by creating a prototype about 24 in long out of light ply. I then created full size plans of the model to be made. Pictures of small prototype finally painted plain green. The Main model Used my computer to print out the frames onto paper, cut them out and used them as templates for the ply ribs. The construction was simple chine style, with 1.5 mm ply. I tried to build jet drives but failed to produce a effective unit. So reverted to propshafts which worked out well with better control and the boat can spin on it own axis by putting one engine in reverse the other in forward and adjusting the twin rudders. That it for now, hope it was of some interest

    Up Grade NDQ speed boat
    This is not a build but a modification of a cheap Chinese boat just for fun, I got a bit bored of scratch building projects as they take so long especially as I am not retired yet. The NDQ 757 Coastal Brother 1:25 Radio Controlled Racing Power Boat cost about £25 each from Amazon. These boats have a basic 27mhz radio and two 380 type motors which have forward and reverse and you steer by powering one motor or both for straight ahead. I bought two of these boats as they are light and about 24 in long, one to convert/upgrade radio, esc and brushed motors. The second was to upgrade radio, esc for brushless motors. The brushed motor version I put in two higher rated motors (390) with cooling fans built in, but same motor diameter but longer body I had to modify the mounts, kept same couplings and shaft/propellers. I did remove trim tabs (fixed) and replaced the straight running adjuster for a racing rudder. The brushless version is the same but has brushless motors 2x 2845 2600KV sensor less Specifications: KV(RPM/Volt): 2600KV RPM: 50000 Max Current: 42A The boats ran well but trimming needs attention, as hull is curved up at the back so trim tabs down, to prevent proposing, in-fact at one stage the boat left the water, but need to distribute weight towards the bow. Tried on 3S (11.1v) for brushless went well but got slightly hot after 10 mins. 7.4v for brushed also got slightly hot after 10 mins., and went nearly as well as the brushless. Surprised!!

    Reused running gear from my old club race to insert into new hull.
    The build has been quite quick using 9cm wide planks and gorilla glue, there are no real plans, but as per the rules of the club, the boat should be semi scale military or pleasure boat.

    Hi Shipmates,

    If your flexi-shaft is leaking water this may help!

    basically a plastic bottle cap with two holes filled with grease to stop water ingress.

    Hi Shipmates,

    Put in the old hardware from club racer v1, added a go faster stripe (That always makes boats go faster it works for cars too.)
    Added windows (Tape), a driver/captain, a name plate 'Fire wood'

    Hi Shipmates,

    After second trial run, still leaks. so have added a grease bucket (not shown). but see above post.
    Also I found it was turning too quick, no control, I guessed this was lack of turn fins, so have fitted a couple of carbon fibre and red anodised fins. see pics
    Have not tested them out, that will be on my next visit!

    Hi Shipmates,

    With the rushed construction and the terrible paintwork I think it will call it 'loft find' or 'Fire wood'.
    This is most probably the worst boat I've made, its a bit embarrassing.

    Hi Shipmates,

    While working on other boat projects I quicky spent some time, roughly painting this old racer, unfortunately this fun class of boat is no-longer run by the club I belong to.

    From my last post I have changed the cabin's shape from an angled front to a curved front. and painted the underside black and the top blue. the paint is very slapdash.

    Regards
    Roy

    Hi Shipmates,

    Did some more work on the cockpit.
    The roof is next, I tried to seal it to stop dust getting in, as a lot of sanding and filling will still be required.
    Added a couple of led lights for the interior.

    Regards

    Hi Shipmates,

    Re Hi Roy, it seems like a very valuable electrical setup, especially the motor and the ESC (they are very expensive I imagine).
    The brushless motor has remarkable performance.
    Can you attach some photos of the propeller area and the point where the water enters?

    The motor cost £56 including water jacket, the ESC has been modified by myself to add water cooling it is a dual direction 125A cost £31.

    I only oiled the shaft but I need to disassemble and add a heavier grease to parts of the assembly, to prevent water ingress.

    Please note that there is meant to be a gap between the prop and the end of the stinger of about 1mm, this is to allow for shrinkage of the flexi-shaft when under load.

    Regards Roy

    Hi Shipmates,

    Added water cooling, servo and water outlets. a bit of soldering for the ESC (125A 6S ) setup a Radio and receiver and a test in the test tank No1 (the bath).

    Test
    Fail No1, Forgot to do up grub screw on the dog drive so prop moved up the shaft a bit, easy fix.

    Fail No2, I've had this before on boats with a low level prop-shaft that is below the water line, yes water slowly ingresses up the shaft, especially when not in motion.

    Cures,
    a) Add grease between outer metal tube and the liner as there is a small gap between them.
    b) Grease the flexi-shaft, but normally a thin oil is used.
    c) The most invasive is to build a grease box around the shaft end in the boat, and fill it with grease as last resort.

    Regards
    Roy

    Hi Len1,

    It is possible that a cable can be damaged if put in reverse at full power, but this has not happen to me personally.
    I never use full power in reverse on a cable drive, some ESCs are set up to limit reverse power to about 50 percent, but not all do.

    one of the main problems with cable drives is corrosion due to poor lubrication and/or use in sea water.

    Hi Shipmates,

    I add some epoxy resin under the motor after making some small dams to keep it in place.

    Add a small strengthing bar across the front and rear of the motor

    Added a battery rack to port stern, to counter prop torque, and keep the COG towards the stern.

    Motor specs.
    no load 1.8A
    Max voltage 38v
    Max current 73A
    Max power 2800w

    but will only run on 4s

    Regards Roy

    Hi shipmates,

    Today I received my stinger by post, after a lot of cutting and filing I got it to fit and made it adjustable up 1 degree and down 2 degrees.

    I have cut down the rudder as a bit too deep.

    I've fitted the motor and had a bit of luck with that by changing the mount to a narrower based one I am able to fit it snuggly between two of the spray rails.

    I have just epoxied the bent shaft into position.

    Regards Roy

    Added some throttle type controls to the right.
    (The reason for the figure is looking serious and a bit frightened is that non of the controls appear to work)

    Hi Shipmates,

    RECAP
    After a few too many bad experiences with expanding foam I though of a less dangerous way to stop my boat sinking (experimental).

    Basically it is polystyrene balls and acrylic paint (white) mixed together so the balls are covered and stick together (patient pending) joke.

    Thus will follow the rough shape of the hull, but will take some time to dry.

    UPDATE
    Unfortunately after a few days the stuff was only dry on the exposed surface.
    So I had to remove it all by hand and wash out the interior of the boat before refilling with dry polystyrene balls and fitting a solid polystyrene bulkhead, which appears to have worked ok.

    Regards Roy

    Hi shipmates,

    The Hull is a well designed double stepped hull made of Polycarbonate (The same stuff they made crash helmets from).

    Have reinforced the transom with some epoxy resin.
    Added insulating foam for pipes into the rounded part of the hull.
    Added some hardware to the transom.

    Motors are on order, gave myself a choice of two
    A 3670 1900kv or a 4074 1550kv the latter may be better in theory.

    Regards Roy

    Hi Shipmates,

    The Polycarbonate Hull
    the only part I will use.

    The rest will be scraped
    (Equipped with Twin 380 Motors Vector-push design for easy control
    Radio Controller with antenna Wall Battery Charger 7.2v NiCD 1800 mAh NiCD Rechargeable battery Extra Pair of Propellers English Manual
    Length: 32 Inches Battery Type: 7.2V 1800 mAh Transmitter: 3 Channel Motor Type: Twin 380 Charger: Supplied
    Skill Level: Beginner / All Levels Speed: 20 - 25 mph+ Battery Requirements: Vehicle: 7.2V 1800 mAh NiCd Rechargeable Battery (Included) Transmitter😊

    I have stripped out all hardware, filled holes in the transom and affixed polystyrene to the hatch / cabin to make it buoyant, so it will not sink if it falls in the water.

    Regards
    Roy
