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".

well club days for members are like i said from 9am till 5pm in the summer all wek bar sundays when its 10 am till 5pm in the winter its 4pm we are hoping no closed season weather permitting our chairman is aldo a duty officer on sight so when he is on duty we can sail till say 8 or 9pm in the summer dont forget we are on a private site so u must be a member to sail on our lake u are allowed to come a sail and see our facilities if ya like it can join , weekends are the most popular time for our members u have to sign in before sailing and when u finish sign out thats about it we have our meeting at the boat musium every second tuesday in the month 7pm at the cafe , so when u feel like it come down a visit us we are a happy laid back club if u are on face book go to our open site ellesmere port model boat club and see our posts regards len
Fantastic stuff, Colin. If you can get that ancient engine to run on diesel from your car plus Methanol, you could get that kitchen nozzle going! Where did you just get some methanol from? I'd say the engine is something like an old ED Competition Special or similar with a very home made water jacket and even more home made exhaust wrapper, requiring tubes to be added to the 2 stubs and led to the stern or either side. Doug's yer man for anything lecktrickal. Is there actually anything of the original RC in there apart from that superb kitchen nozzle affair, which deserves to be preserved all on it's own. Control will have been vestigial at best as the engine has no throttle and the nozzle arrangement will not have had any level of proportionality to it. It will, at best, have been push the button and see where the boat ended up, knowing it could, at a a pinch, be brought back to where it started. At one time all RC was like that. My own REP set was left,centre, right, centre, etc. A wonderful throwback that must be preserved. I wish my local junk shops had stuff like that! Cheers, Martin
It's a disgrace how bad some plans are from the suppliers. I bought an aircraft drawing to make a De Havilland Hornet Moth. It was about 15 quid...more than enough and was so appalling when I got it back that I had to redraw large parts of it. Arguments about accuracy are one thing, but when the side view and plan of the wing is different it's time to cry "foul". I paid what I thought was an appalling amount for Harold Underhill drawings of a Scottish Zulu fishing boat, but at least they were very detailed and accurate. Mind you for that price they damned well should have been! And don't even get me started on the plans drawn by Gary Griswold of runabouts and mahogany hotrods. I made the one called, (wrongly) Excaliber. It would not support a sigle fair batten through any of its frame's notches, so I added little bits of wood and took some out with a cutting disc until they fitted. Then I realised it was twisted, so had to add a strong diagonal brace while I corrected all the notches. Fortunately, after they were all corrected the brace came out and finally I was able to add skins. I figured it looked like a Greavette racer, so have built it like that. But no thanks to the lousy drawings. Cheers, Martin
I thought as the lake is still full of weed this would keep me sailing built from light ply fibre glassed inside & out then painted length 33" width 12"height 16" to top of the prop 70 amp esc aircraft brushless motor 11" prop I am busy with a landing craft i thought this would be another one to beat the dreaded weed 😱
Last I saw t, he showed it working. Alas he has been stricken with Alzheimers in the last few months. I was asked not to go round as his wife had had a fall and it was all rather awkward round there. So suddenly a good old friend (he's 84) has been taken from me. What will happen to all his stuff, I dread to think. There are over 50 flyable aircraft in sheds, caravans and his large loft, even some boats. He gave me a GRP hull of the Bloodhound and a freelance, very early GRP cruiser hull. I shall attempt to finish them in his memory, because it's like he's died. That E.D. RC set should be in a museum, but there ain't no model museums. Martin
Aha, I assumed it was an airyplane motor. I had an Ugly Stick once, given to me with a speed 400 motor and a gearbox with a bent shaft. So the motor came on board as a spare and the gearbox was dumped, but I stopped doing aircraft and so gave the Ugly Stik back to its reluctant owner. There's a whole range of Ugly Stik type things, all ugly and odd looking but apparently they fly very well. Looks like your photo shows a brushed 380 type motor with gearing too. Not sure about the 62mm length! It's way shorter than that. Has, as you can see, a flange mount. There's no mount for the blue one. The magnetism is amazing. I can hardly turn the shaft with fingers. So, do you reckon the motors would work in a boat? Cheers, Martin
Post 2 Range Launch? The bath test has shown up a leak……………….. Have not tried to find where yet but it is hopefully in that small bay as it did not flow over the rib section. Strange I had not thought leaks to be much of a possibility in a boat! Wishful thinking again. Anyway it has put work back a bit. You will notice that the bath water was ‘used’ condition. I was not allowed to waste water due to the shortage so had to use the bath with Radox and herbal Oils in it. I trust it does not affect the paintwork…………… Any opinions on Leak Checking? I did check how it ‘sat’, and the waterline at its current weight. There is something in those images that RN Munich will pick up on! Have received some of the parts………….just like Christmas for me. ( I was a spoilt only child). Two issues strike me. a. It may be of interest if I give sources of the parts b. I think I have a problem with ‘scale’………….. Currently the purchases fall into two groups, electrical and deck fittings. The electrics are not posing a problem yet, but the size of deck fittings certainly is! Taking the larger ‘electricals’ first, I have gone for pre built units. Someone with more ability could build the units themselves. Kits are available. Also far fewer units could be used to start with and added later if needed. As a result of my previous, though small, experience with the Richardson Tug I used Action Electronics and Component Shop in Bangor, Wales for almost all of the electrical bits. They are helpful and efficient with good quality products. I am still using Mtroniks DigiSound for the sound unit, but Action Electronics now makes one as well. I have used a new source for the transducers/exciters. I have previously used Dayton Audio, sourced through SoundandVision Netherlands and costing around £35.00 for a pair of TT25’s plus mail. This time I used Mr RC for similar item, made by them for about £53.00 the pair mail free. They too came from the Netherlands! Not tried yet, but have noted that the Dayton Audio ones had a foam ring on the face which was self adhesive and easy to place. Mr RC require Gluing in place. Going to look for the leak. Next post should be on the electronics which I hope will have arrived by then. BTW, The 46 Firefloat Mk2 blogg by ‘Elsrickle and Fire Boat (Crash Tender) on our site are great sources of information. NPJ.
Thanks Westquay. I like your comments about air boats not being used much anyway. This is very true. Even if the boat was powered by an electric motor there would always be some miserable sod who would complain about the rotating airscrew. Boaty😁😎👍
Don't do it! Use a river or a public lake. We HAVE to middle finger the arseoles who would have us using electrics as a matter of course. Rivers and canals can be used with ease as the real thing is already dirtying up the water, which, of course, the wild life are well used to. As an air boat would never be used that much anyway, keep it for when you travel to a river. Keep the electrickery for the Jobswuffs. AM 15 is a great little motor. I used to have one. Alweays started easily. Trouble is these days the fuel ain't exactly cheap, but then, neither is a brushless motor, Li-Pos, special charger, watt meter, battery condition meter, special wires and connectors, and of course special ESC which will almost certainly burn out like they all seem to eventually. Failing that put it on the shelf and await interested questions! Martin
I recently acquired an air screw driven hydroplane fitted with an A.M 15 diesel engine. The boat appeared to have either been from the Mercury Kit which was produced from the early 1960s till late 1970s or may have been built from the plans. What was unusual is that it had been fitted with R.C for rudder only operation and when I put a receiver in to try it, the system worked well. I also ran the engine and it appears to have been as new and after examination of the boat this appeared to have not been used either. In the 1960s I had built a couple of airscrew boats and they were free running powered by engines taken from my control line model aircraft after they had been pranged. Intentions are to eventually get the hydroplane on the water with brushless electric power due to the "No I.C" rules on my local boating lakes, something I never had to worry about as a 15 year old .

Speranza is a lovely boat and handles nicely but don't undepower it. Vic's Pond Skater is a good flyer and can be converted to leccy and rc. I put a half circle of piano wire across the tips of the front float as a buffer in case of striking an obstacle. My motive power Was 1.5 diesel a prop cut down from a heavy nylon 9" one so just clears the hull/frame . Free running was loads of fun. Air rudder not water. If it is sluggish and won't plane increase the downthrust. The opposite of what you might expect. Regards John Pond Skater can be found on Web Google Vic Smeed Model boat plans. BTW an original thread can be found on here with the title Scudder👍
Ain't got no 'air! Hmmphh, that's that bit o' fun stuffed. Women are like wattmeters. Lived without em for years then got caught! Now I got beautiful granddaughters! Where did all those damned years go? Wattmeter ordered. Bloody thing was 50p dearer twixt this morning and just now, while I was in Kings Lynn buying wood for the boat models and McDonalds for the grandson! Martin
I used to scratch build aircraft 50 years ago and thought a kit might just ease me back to modeling (sorry Martin) however I'm doing a scratch build along side my crash tender, its actually a kit but needs a lot of mods as the plans are not as good as they should be so is near enough scratch. Can anybody tell me the difference between scratch and kit building? I think that a lot of scratch builds and kit builds may not be built to a "production standard" however they are built to the best of the builders ability, conversely there are boats (both kit & scratch) on this website that are built to exceptional standards with kits being modified from plan, I've never seen two "same models" that are the same. Each to their own. Any chance you could share your woody plans Martin?
I have often admired Thames Barges in Maldon and on the East coast rivers, but find their complexity off-putting, fine , majestic things though they are. But for me the simplicity of a Norfolk/Suffolk wherry is very attractive and there are few books so much worth curling up with on a rainy November day as Black Sailed Traders by Roy Clark. OK, I can think of several, but you know what I mean. I am a very fussy sod and if I don't like how it looks, I can't get near it. To my eye, most foreign stuff is so much uglier than British, be they trains, cars, bikes, aircraft or boats. But then where would we be without Canadian woodies? Or the very occasional Italian car Martin
