Hi Onetenor Fuji 15 was a good glow engine which I don't think it is manufactured any more. Aero version max B.H.P was just below .40 when tested. If it was in a model aircraft it would have been around .20 to .25 depending on prop size which was good then for a small capacity glowplug . Marine versions when on the water put out a little less and the water cooled jacket was never as efficient as the finned cylinder jacket of the aero version. My two Aerokits boats, the Sea Commander and the Crash Tender are powered by single Speed 600 motors running on either 8.4 or 9.6 volt Ni Mh batteries. Performance is equal to that of marine diesel power such as the 2.46 Ed Racer and D.C 2.46 Rapier, the latter I used to watch in the fast steering events in the early 1960s at Fleetwood and Coronation Park in Crosby just outside Liverpool. Taycol powered versions would be obviously slower due to the additional weight were far more reliable and you did not have to put up with injuries from excessive use of a starting cord with kids watching and "extracting the urine" shouting "why wont it go mister".

Hi Martin, Apropos mini Milling machines; this is the one I use. https://www.youtube.com/watch?v=qffdG_d2fJ0https://www.axminster.co.uk/proxxon-mf-70-milling-machine-37... Pics show using it to mill my new Sea Scout propshaft to secure the grub screws in the motor coupling. I just changed the tool holder from collets to a proper chuck. I also bought the little machine vice which clamps to the table, and the dividing head. There is also a CNC (putah driven version - ain't got that far yet, bit expensive😉) But this little job has served me well for several years now, very happy with it👍 I also use it as a precision drill press; e.g. to make the new phosphor bronze brushes for my Taycol target renovation. See last pic. Have also recently used it to make the little gearbox so I can fit the renovated Taycol Target into my ancient Billing Danish fish cutter 'Gina2'. See, I don't just do the 'Grey Fleet', sometimes I also mess with wood😁 Cheers, Doug 😎
Hi Gardener, Don't know the Sadolin stuff, I use Billing Boats stains meself, BUT whatever you use, esp on balsa, apply a coupla coats of sealer first. Then at least one or two coats of clear satin varnish; e.g. from Lord Nelson range from Holland. THEN AND ONLY then, apply your stain til you get the depth of colour you want. After that seal with matt, satin or gloss varnish / lacquer according to taste😉 That's the way I did my Sea Scout 'Jessica' renovation, see blog on this site for results!!! Coupla sample pics attached. The whole process is described in the Blog. Otherwise the balsa will soak up all your stain and still not look right 🤔 A 'preserver' as such is not normally necessary if the wood is properly treated inside and out; sealer, stain, varnish etc! Or just EzeKote resin inside. Stain no needed inside of course. Good luck and above all have fun with your endeavours. 👍 Keep us 'up to date' ('on the running' as my German friends would say; 'auf den Laufenden'!) 😁 Cheers, Doug 😎 PS I like Danish Blue meself 😁😁 On the other hand; I wouldn't have used balsa for speedboat deck in the first place. I use a close grained marine ply 0,8 or 1.0mm. Takes the stain better and looks more realistic. Balsa is too coarse grained for stain and varnish on scale speedboats. Thick coat of paint ... OK. On the cabin roof and after deck (which I had to renew) I used 1.5mm mahogany veneer. If I had to do it again I would use a close grained 0.8mm marine ply (birch or pear) and cherry stain (also Billing) as I used on 'Jessica's deck.
Shucks! An I was hopin' you'd build me a little 4 cylinder diesel for me to run a brushed motor as a Genny for all the lighting on my ships! Or for the diesel electric propulsion on my Type 45. Now wouldn't that be cool!?😁 BTW Some of Nick Carters tips an tricks showed me how to convert one of my tools to something that'll do what I want! So, out with the Proxxon mini-grinder😉 Cheers, Doug PS It wasn't a wrong steer cos it led me to all sorts of useful 'stuff' and above all helpful info👍
Colin May I suggest that you cover up that Mills c/case. It will oxidise and the oxide won't protect it from water especially salt water.A crinkle/crackle finish or Hammerite smooth( or hammered if you prefer ) would suit.👍 When are you going to tell me what the proportions of diesel to Methanol were?👍.
Mornin' John, agree re chromite, but still don't know what chroDite is! I only personally own the one Taycol Target. I got into this whole Taycol business while I was renovating Dad's old Sea Scout last year and decided I wanted a bit more Oomph so upgraded it to a 1000kV brushless, which gives goods results on a 3S LiPo. See the vids I've posted of the the 'Sea trials' (Lake Trials!?). So I decided to use the Target in the ancient Billing Boats Danish fish cutter I'm restoring and converting from static to RC. Figured the Target would cope OK with the plodding pace of a fish cutter😉 BUT, I wanted it to be reversible without cumbersome external switches or relays as recommended by Taycol / Keil Kraft in those days. After surfing around a bit a found a website where others had tackled the same problem. Looked at their solutions and refined them slightly. All I do is rectify the pulsed (square wave) signal from the ESC with a bridge rectifier (4 hi-current diodes in a bridge form in one package), apply the + and - outputs from the rectifier to the field coil so that it produces a constant magnetic field just like the permanent magnet of a canned motor. The two alternating (pulsed) outputs of the ESC are applied to the AC (~) inputs of the rectifier, which go + / - or - / + according to the command from the TX, I apply to the brush terminals just like a normal brushed motor setup. The output of the ESC is a train of either positive of negative going DC pulses. Pic 2 the positive train on the scope. Pic 3 the negative train. The larger and wider the pulse the higher and longer the voltage is applied and the faster the motor spins. So called Pulse Width Modulation (PWM). The gaps between the pulses are smoothed out by the inertia (flywheel effect) of the motor, and anything hanging on it - like a prop and a few million gallons of wet stuff 😁 Hey presto, a field coil motor that runs forwards or backwards on command 😊 Main thing is simply to separate the field coil from the armature coil (i.e. brush gear) so you can control each one independently. No rocket science but highly satisfying when it all comes together and works on the pond. OK, I'll look up Mr Lynch, wasn't he the Sarge in Z Cars 😁😁😁 Cheers, Doug 😎
Hi Steve im not sure now regarding motors as they have water cooling cans on but Surfury runs from memory a 1075kva motor Turnigy 160 A speedo watercooled on 2x2s 5200 lipo`s in series ie 14.4volts with 52mm mocom Alum prop approx 3hp. I think the Tornado has approx 2045kva motor same speedo + lipo`s x 50mm nylon prop both do scale speed to as fast as 40/61 IC and look great on our choppy water with just prop and rudder in the water. Both motors will take 6s if you like ballistic? All gear from Hobby king. Try the IC first, post some pics please
Don't remember Joe Lynch but John Bluthall was brilliant 😁😁😁 PS OK, I'll leave the shafts at 6mm, less a tiddly bit for the oil film! PPS Apropos lathe spares; I'm having a little trouble finding 6x6 tools for it. the Proxxon spares are a bit pricey🤔 Oh well, there's always the grinder! (Also Proxxon!!!)
I sold a Taycol Standard on Ebay about 10 years ago and got £34 for it. I will tell you the wierdest of stories. When I was 8 years old, my father (still going strong now) made me a 36" Daytona Cabin Cruiser which was B and B constructed from an old pair of wardrobes so it was massively heavy and completely underpowered by a Taycol Star which ran on a large Eveready block battery. We used to sail it in the paddling pool in Dartmouth Park, West Bromwich. That was in the late 1960's. In 1991 I moved to Bournemouth and bought my property in Southbourne in Cranleigh Road, near to the junction with Beaufort Road and my rear garden backs onto the gardens in Lingdale Road. Check out the Google Map and Taycol booklet I have uploaded.😊😊😊
Chrodite!! Blimey I thought I would never meet another person who knew that word. My friend had a load to make fixings for his tiny, but lovely Crouch sloop White Mouse. He gave me what he had left and I'm down to about a foot left, so that goes towards making prop shaft bearings, so, Doug, you've actually got a wee bit already. Martin
Hi Boaty, The Taycols have fascinated me as well, ever since I dug the Target out of the Sea Scout my Dad built in the early sixties. I blogged my renovation of that and the conversion to run with a modern RC system and presumably that, and the converter boards I built for Martin (Westquay), is what triggered Colin to ask me to have a look at his Supermarine. How could I resist!? 😉 The 'smell of something electrical' is the ozone gas caused by the prolific sparking of the Taycol metal to metal brush / commutator combination. The other source of Ozone is on the coast wherever there is a strong surf! I agree, a nostalgic smell, which unfortunately disappears when the converter board is attached to make it run with a standard brushed ESC. The diode bridge kills almost all the sparks. 'Almost' so the usual suppression capacitors are still recommended. 0.1µF across the brush terminals, 0.047µF from each terminal to the motor can, or frame in this case. Earth to prop shaft tube as well if possible. The motor may not disturb the on-board electronics of your own boat, if using 2.4Gig, but could still affect anyone nearby using 27 or 40Megs. The power density of spark transmitters (e.g. unsuppressed E-motors, peaks in the upper HF bands and diminishes to almost zilch in the UHF bands. I.e. approx 300 MHz upwards. Like me and other submariners for instance; 2.4Gig is useless for subs cos it don't go underwater. Cheers, Doug 😎 But here! BTW Boaty: where are the pics of your Avanti? Harbour posts without pics are pretty dead 🤔 Cheers, Doug 😎

This is my scratch built 36" RNZAF British Power Boat 64' HSL (arrived in NZ 1940). I actually went on board this vessel in 1968 when it was still in original form (the RNZAF having disposed of it in the 50s) This vessel is still around and has been recently re modelled (2nd time since early 70s) and I was lucky last year to have met the present owner and go on board (2nd time in 49yrs!)and take a few photos. The vessel was modified a number of times by the RNZAF over the years (air intakes, removal of the fore deck machine guns, wheelhouse turret etc so I sort of went in the middle. I found a few drawings of the type in an old mag which had side and top views plus the bulkheads and their positions, so I took them along to a copying shop and kept enlarging them until I had the desired proportions. This worked out quite well and using a few methods from other models I had built, managed to frame (ply) the hull and then fully strip plank it in balsa. It was then fiber glassed. The deck is ply, lined and varnish stained. The wheelhouse is varnished balsa with the top removable for access. The wheelhouse interior has detail such as controls, instrument panels, skipper, steps to wardroom etc but is not too detailed as it is not seen. The boat has full lighting by remote switch, lights are all LED. The propulsion side has dual everything (motors, ESCs, sound units), would have had 3x but ran out of space! Motors are 28mm 2200Kv water jacketed in-runners (cooled by remotely switched pump) using 30A Chinese ESCs (have 5A BEC, Fwd and Rev). Twin sound units are 'GT Power' car units which have around 40 different sound selections, from Cosworths to diesels and are computer programmable (as well as manually on the unit ) for various functions. I am using one of the v8 sounds (8 cyls short in my application) which I think is as near as you are going to get to 3 Napier Sea Lions (for which there is obviously no sound available) They 'start' 'Idle' and are fully proportional in fwd and rev and can sound quite realistic (will attempt to put up a vid later). Batteries are 2x 2200mah 2s 20c LiPos which will last around 2hrs at least of sailing (they also run the sound units) Still have a few small things left to do (have just made wheelhouse air intakes) but don't want to get too fiddly. Just want to keep it a practical model.
Just got white metal castings back of the Chris Craft fittings and very nice they are too. They have started to burnish up a treat and will polish well as Paul uses a good quality metal. Nice and hard. Now I have to make the light lenses. Also put the blue bottom on her at the weekend using my one and only pot of Plastikote enamel paint, not the acrylic muck they've turned over to and it went on through my spray gun as smooth as could be. Even my masking worked. Just waiting for a gold pin stripe tape for the boot topping now. The final bit will be masking the deck to paint the covering boards and king plank with the same blue. For those not lucky enough to have a wee pot of proper Plastikote in the paint cupboard, I also got a couple of tins of Rustoleum spray, only 5-25 a pot, enamel (of course) in a nice French blue and a rich cream. These colours will look good on my Darby One Design single stepper "WHO'S DARBY?". Very post War. I think the Oulton Broad One Design single stepper will be Burgundy and the Whippet One Design will be varnished mahogany. I know of no other classes of British stepped hydroplanes. These will all be 1/6th scale as they're all around 12-13 ft. long. I'll probably put the same motors in them eventually. The Darby is well advanced and has a Speed 400, but I may go brushless. Any suggestions for a cheap Brushless/ESC combo will be welcome for, say, 3S Li-Pos. It would be good to see these period boats all racing together. I also plan to make reverse clinker Singer cadet and a Percy See Bugatti engined boat for which I have plans. I'm hoping to get a response from the current keepers of Berylla II about measuring that, too, since it also uses a Lea Francis engine, like the Whippet.
My dad built this over a long period of time, starting in the '80s. The hull is fibreglass and the rest is scratch built from plastic card, balsa, ply, wire and anything else he could adapt. Although he installed the motors, props and rudders he never completed the RC installation or tested it. I inherited his boat models a few years ago and wanted to "finish the job", getting the model on the water. After installing the RC gear and batteries over the last few months, this weekend was the first sailing outside the bath at the Valley Gardens boating lake. Happy to report that it sailed really nicely, seems to be reasonably stable although I did restrict it to calmer times when the MTBs and faster boats weren't running ! HMS Cadiz was a battle class destroyer, laid down and launched during WW2 although she didn't receive her commission until 1946 so didn't see combat with the Royal Navy, serving with the home fleet. Due to the changeover in pennant numbering she was originally allocated R09 and later, when the admiralty decided to revert to the D for Destroyer pennant numbering she was assigned D79. To reflect this my model has D79 on the starboard side and R09 on the port side. She was sold to Pakistan in the late '50s, and renamed PNS Khaibar. She was sunk with the loss of nearly all hands in 1971 in the Indo-Pakistan war.
