HI This is a Celia, I think, it was a caldercraft kit but am not sure. it is running on a 545 motor at either 6volt or 7.2volt with a 35mm 3blade brass prop. its performance is about right for the scale and type of boat. it sails at the Lake used by the Cwmbran Club. I bought it last year at the Shepton Mallet Show.
Yes this was a Caldercraft kit I built one and sailed it but not much room under the decks for your radio and batteries but really sailed well when set up right
I built this one about 3 years ago she is built at 1/24th scale 50"long and is a plank on frame hull , scratch built using lime wood planking and 9mm ply for the frames and keel, the rest is birch ply of various thicknesses.
she has a 12volt cooling fan motor driving a 4" prop,and has a 12volt 48amp hour battery ,plus some lead for ballast,with working lights and revolving radar scanner
HI Ralph we have a launchung crane at our club so it is not really a problem with size and weight, most of my big tugs actually weigh less than 30lbs without the battery and ballast, I use 46amp hour gel cell batteries where possiblt and then trim with lead blocks ,the Atlantic Cock has her battery plus 3 x3lb lumps of lead so she goes into the cradle light, then is loaded and launched mechanicaly simples really and no bad backs. George,
I have just completed this model - just waiting for the new prop to arrive along with a flag for the main mast, plus handrail staunchions. it was a Precedent all wood kit and not too Impressed with the materials but you only get what you pay for. I have fitted a Graupner 700 Speed Turbo and a Torpedo 50 Amp ESC. I am powering it with 2 6 volt SLA's wired in series. Overall I think it has turned out not too bad and it seemed to get better the more I worked on it (or is that psychlogical)Tested in the Marine testing laboratory (white bath) and floats OK with no sign of a leak (fingers crossed). Our boating pond will be frozen over at the moment so no real testing can take place yet.
HI Dave
Yes, my ESC is a Tornado 50 Amp which is the same as my friend's one - in fact I bought it on his recommendation, however I usually use Mtroniks. Our motors are not the same but both have similar RPM at 12 volt. I have ordered 3 more props of varying sizes and pitch to see how it will perform - had I have seen my friend down the lake in the last few months since I have been building my Perkasa, I might have got the prop right to start with ! I don't think I will get a 'pass' to get down the lake before Christmas so hopefully it will not be too cold and freeze the lake again before I get a chance to try her out.

Down at the lake this morning. Boat is now complete with hand rails fitted and painted. 40MM 2-blade X type prop fitted and with the batteries moved back she went really well. The bow lifted well out of the water and got on the plane very easily - would not want or need to go any faster.

I love this video, thought you might like to share it, taken at St Helens model boat club lake, which is Taylor Park, Prescot, St Helens, very early before anybody arrived, on a cold sunday morning!
Shortly after this video I changed the motor and prop, I never stop meddling! 😀 Reposted - now with footage! Stephen
HI There, I like what you've done with the boat it looks great.
The boat my father had was lost in time but when we sold the house I came across the plans, little bit moth eaten but decipherable.
I want to start and rebuild the boat within this this year from totally zero but don't seem to find many "parts" for it.
I Like originality in looks but love new technology built in as well.
Is it possible to ask for some pictures that I can use for reference when building please.
Two Wavemasters, both refurbished ebay rescues, sailing at Crealy, near Exeter (one of the last times as the club can no longer use the water).
The first, rebuilt by Kalamunda, is brushless with NiMh cells and the second, having it's first sail since being rebuilt by Ian Gardner, has a Graupner 700 with 3s Lipo's (in parallel) on a 37.5mm X type prop- Electronize 30amp esc.
I think these are lovely looking old boats designed by Les Rowell of Aerokits fame, and obviously based on traditional cruisers from the Norfolk Broads- see Martham Boats, where you can still hire a wooden craft like these, although you'd definitely have the river inspector after you if you sailed up the Thurne at these speeds!
HI Graham,
Glad you liked the video. They are smashing boats aren't they? I really fancy a new IP Engineering one but have too many other projects on the go to make it a sane decision!
I have to say my WM is the best running of my faster boats, which include a Lesro Sportsman and a Rapier. She seems to hug the water in turns rather than bounce around, so a great design I think. I'd be interested to hear how you arranged you gearing on your WM. Did you make it up or but a ready made unit?
Ian
HI I bought them on Ebay, from Hongkong, they were about £9 plus some small amount of postage they have a brass motor gear, and an aluminium gear for the propshaft I use the system on three boats the Wavemaster a Sea Commander and a Fire Boat. On the water with 7.2 volts but will also run on 9.6 volts and 11.1 volts 3 cell lipo's. I will try and get a photo of the motor and gearbox. Regards Graham
Not Strictly Aerokits!!! Bought this and a Sea Breeze at the Warwick Show. Sea Breeze is in the cupboard for Xmas. Sea Nymph is Ivory and Brunswick Green. it has a JP 400 motor with an Mtroniks 15 amp esc powered by a 7.2v nicad. Currently it has a 35mm S prop. Haven't had a chance to try it out on the water yet. Maybe this weekend. its the first wooden boat I've ever built so am quite pleased with the outcome. Looking forward to the Sea Breeze as that's going to be my first brushless model.
I finally got round to trying the Rapier with the lipos I bought recently. My good friend 'Kalamunda' was on hand to drive whilst I took the video. We noticed a marked Improvement in performance- a much greater 'urgency' with the lipos delivering what the motors asked. Short of going up a prop size I think this will be about it with this boat. Thanks to the chaps on here who have encouraged me into Lipos and given help with various matters- not sure what all the worry was now- famous last words!
This will be one of our last days at Crealy in Exeter as the management have decided to terminate our use of the water- so we will be looking for alternatives from January.
I use a little "plug in" voltage alarm on my lipo's. it simply plugs in to the balance charge plug connector. so give you an initial volt test,usually with a few bleeps and a set of green lights, then as the batteries drain, the led's turn red and an alert buzzer goes of as they approach low volt limit, which is set on these alarms at 3.2v, so no damage done to the batteries.
Its a quick search on ebay, loads of sellers, cost around £2.50 each.
very useful bit of kit poolside as you can check all your lipo batteries, even after being used and left to stand, the batteries do recover a bit and possibly ready again for a further shortened run time too.
Those are the alarms I intend to use but they seem to be taking a while to come. They are so cheap I intend to install them in the boat with velcro and extension leads on the balance connectors. The lipos certainly give a weight saving too.
A freind from a photographic club has kindly forwarded these pics to me. Well, you know what its like when you are at the controls, there is never anyone around to take any decent pics, but think these are superb, especially when considering it was going almost flat out at the time, and plenty of "air" under the forward hull, right up the tha last "step" in the hull at the stern.
11.1v lipo, 3000kv motor and standard 3 blade 32mm plastic prop.
I found after some "trial" that the ORIGINAL plastic prop suited the motor better.
I did try a specialist one from prop shop and it actually ran slower, albeit same diameter, but with bigger pitch.
Ok, thanks for that info. I have hot shot tunnel hull and a 47 insane v-hull. I'm big on the fuel driven, nitro or gas. I've been exsperamenting with perpellor size and I've come to the conclusion that I need to get a GPS or other type of tracking device to determine if their is some tpye significant change happening with the performance. I'm just starting this hobby , so is there any recommend reading you would suggest or general knowledge site I could look on for beginners. Thanks in advance for any more help you can provide.
1965 U.S. Lindberg Plastic Special Edition John F Kennedy P T 109 Boat. The P T 109 boat was mainly employed around the islands surrounding the Philippines, hence the reason why the boat was painted to match the background colours of these islands. Bought in a part built state and took me, with help and advice from other model boat guys, about 12 months to get it up and running. Powered by twin motors, shafts & props, with a single 8 cell 9.6 volt battery.
Hello:
I've got a scale model of the pt-109, lindberg and want to build it as soon as possible.
Thank you for these photos... very well achieved the warlike atmosphere of the period.
Soon I'll post pictures of the work.
Hope this is not considered inappropiate to post this video here as the majority of videos are about baots on the water (hope mine will make it one day) - but would like DaveM (Fleet Admiral) to have a look see.
Just glad it worked out- always a bit worrying recommending possible destruction! I've got another ebay rescue- Maycraft Mercury- which I shall have to tackle this job on.
HI there guys, I am just in process of renewing prop shaft in my 34" fire boat, have for years run it with Ic engine, as not permitted on most sailing areas now Im converting to electric, I have removed the shaft and tube (badly worn from Ic engine use) all I did was firm grip with pliers on the tube twist to dislodge glue and filler then knocked out of the hull from inside.
my intention is to use a speed 600bb for power any comments on power set up would be helpful, my boat weighs in at 2268grams.
