This model was scratch built from US Coast Guard plans. The boat is constructed of balsa wood and the hull coated with fiberglass resin. All the deck gear is scratchbuilt from brass, the propellers, led's and figures are the only commercial parts. Scaled at 3/4=1 foot the model measures 42 inches in length.
It's powered by a Pittman 12 volt motor and controlled by a 4 channel radio. Working features are running and spot light, siren with flashing blue light, sweeping radar antenna and deck lights. Built in 1985 the model the lifeboat is accurate in appearence for that time period.(The prototype has been modified since).
The actual lifeboat is attached the the Coast Guard's Motor Lifeboat School at Cape Disappointment and is one of four boats of this class.
The way that I do my hull plating is......to use printer paper about 90gsm, and divide the hull up into approriate lines horizontal and vertical to represent the plating once the hull is sanded and smooth of course.
then cut the paper into the sizes that you need to represent the hull plating.
then thin down waterproof PVA glue so that is like double cream and then to represent the plate joggling lay each piece onto the edge of a steel rule so thar about 1/8th is overlapping and then run your thumb nail along the edge of the rule this will give you a joggled edge, repeat if you need more than one joggle per plate, have a practice first and see how easy it is.
then just stick tmen onto the hull using the PVA glue remembering to overlap the joggles ( I like that word). Easy peasy.
once every thing is really hard and dry ,give the paper two or three coats of the PVA all over and it dries like glass.
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,
Well, it took 24 years of "on again-off again" building but now its finished. I started the model the day we put the CAMPBELL in commission(I'm a plankowner) in 1988.The model measures 6 feet in length and is scaled at 1:48. The entire model is scratchbuilt from wood (hull, superstructure, deck) and few commercial parts were used. it's powered by two Dumas 12 volt motors as a direct drive system. I had hopes of adding working features such as lights, rotating radar antennas, articulating gun, working anchor but I was just happy to get it finished! it will probably make at least one run at the lake come springtime but the models ultimate "homeport" will be a museum, at 6 feet in length(and 40 pounds of ballast) it's a bear to handle just to get it into the car for transport. Still, I'm happy with the results, it was a model of a lifetime(but I'd never build another one like it)! 😉
Time well spent and the end result justifies the time taken. Please let us see some pics or even a video on the water before you berth in the museum 😀
I know the feeling re large heavy models but on the water they look so magnificent. 😀
Looks fantastic and what an achievement. I agree with Dave, it would be great to see some action shots before you 'retire' her to a museum. My heaviest boat is 25lb and I don't like carrying that any distance! She doesn't bounce about though.
This Is a scratch built paddle steamer named "Jeanie Deans "
This was scratch built apart from the fibre glass hull which I purchased.
Model is 65" long with a beam of 10". Power is by electric running via a gearbox at 300 rpm. Ihave taken almost 2years to complete the model working most days on it. Attention to detail was the order of the day.
I am using a Planet T5 Tx and Rx, 5 channels. I have a smoke generator pushing steam out of the twin funnels,synchronised to forward speed, faster the revs, faster the steam. Conventional rudder operation.
Have an operating Radar, ships horn, simulated steam noise varies as speed is altered, full navigation lights,all cabin lights can be switched on and to keep the 106 passengers happy I have a Banjo Band playing to complete the scene. Have sailed it recently at Peterborough and performs really really well. Have to say it tends to attract a lot of interest.
I am now constructing the Ayton Cross tug in 1:32 scale, with all the detail I want.Plan is to tow the Jeanie Deans around when completed as well assailing her
This is a 40" long model of a gas powered Berkley Company kit of a US Air Force crash boat from 1955. The plank on frame kit was in production for about 10 years and was meant to be powered by a model airplane gas motor with a single shaft. it depicts an experimental 50 knot rescue boat (painted in a peace time color scheme) during service with the USAF. if successfull it would have been put into production designed to be a replacement rescue craft for all Air Force 65' crash boats. Unfortunately for the crash boat program the Air Force lost interest as helicopters were become a reliable way of rescueing downed pilots along the coast. The prototype and a sister boat were scrapped, as was the entire program.
The model was given to me to be restored(top picture) for the son of a retired USAF veteran that was a crash boat crewman. The model was built in 1957 and had been run a few times on a tether line, R/C was pretty expensive back in the day. I stripped the hull, filled in all the cracks and rebuilt the mast. I added a small boat, davit, liferaft, coxswain station, spray shield and deck hardware among other things. Actually all the owner wanted was a paint job, he was very happy with it's new appearencep! Although I fiberglassed the wooden hull and made it watertight, the owner doesn't plan to run it, just a memorial to his dad's service. I really enjoyed working on this "rare bird".
Based on the US Coast Guard 36' motor lifeboat, the Canadian Coast Guard operated a number of these boats modified for cold weather operation. The model is a fiberglass hull, the reat is scratchbuilt using baltic birch wood, brass, and plastic. The model measures 28" based on the scale 3/4 inch equals a foot. it's powered by a 6 volt Dumas motor and operated with a 2 channel radio. A fun build!
Thats good frank glad everything has worked out okay.
Duration of battery is very good.My boat runs on 29mz.
This is the first time I have used a brushless motor.
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.
Finally managed to get a fellow club member to take some video for me.
This is a hobby King Tunnel hull boat, running a brushless motor and 11.1v 3 cell.
The weather was a bit windy, hence the rough sound, the water too was slightly choppy, any worse and I would of not run the boat, too risky flipping the hull over !
The boat itself was yet another ebay "rescue" item, sold by "cash converters", all I say it was a great pity the previous owner could not afford to keep it, its a fantastic piece of kit, and so, so much fun to handle. he also did a superb job of applying a different set of decals and repainting it, so thmbs up to this guy, hope that some day he finds this site and the video clip.
Your boat is still being appreciated and being run "as it should be - full throttle"
Its an exciting "ride", full throttle is not for the faint hearted [ha ha]. its a total difference to my normal sailing modes, as Im more used to "scale sailing", so being let loose occaisionally can be fun too. I think everyone should have one, a fast boat that is, purely just for the adrenaline rush you get.
