Ahoy
here is a few pictures underway and display of my 1978 issue Lindberg PT-109. I had this old boat for 32 years for power nothing to get excited about. not to much into speed but she goes fast enought not enough to raise the bow out of the water. I didn,t use the kit motor it was to much of a toy its design was primarley used for pool opperation. there for I replaced it with dumas 6 volt electric motor useing the kits reduction gearbox they give you. at the time of the build I had no forsight discard it, perhaps in the near future Iwill scuttle it and use 2 direct 6 volt motors the gear reduction slows down the speed pretty much if you use scale speed it is good for cruiseing at 6 knotts. the gear reduction has been coated with grifite grease as long as I had this old relic there are no wear on the gear teeth so she is good to go untill I decide to scuttle this old gear box. Here are a few attachments of this ols sailor

I just finished this ship, based on my Fiberglass hull. Ship is powered by 3x Speed 600 with gearboxes 3:1

gearbox fitted, tested today with 8.4v graupner, running on 19.2v nimh. GPS Data logger installed, measured at 14.63mph, sound like a jet turbine!!, and this video was the slower of the 2 props tested.
Improvements with gearbox, motor is stone cold (it is water cooled, but was still hot as direct drive) , quieter, longer run time, esc cold, now able to upgrade from 2 blade 40mm prop to 3 blade, and possibly 4 blade, amp draw much less. Video taken at Newsham Park, Liverpool. Handling is now difficult, as its going way too fast, but its great fun! and might go faster, with the motor thats been fited tonight, watch this space!!

well that was the distant memory of brushed motors!, way back when we had gas lanterns instead of LED's 😀
Unfortunately I cant remember the ratio, I think it was 2:1 from memory. it was later converted to brushless. Has not been run for two years since the bigger brother fireboat came along. I keep thinking just put a brushed motor back in it, and have plodding speed, it looks silly doing all that porpoising, and the bigger brother can give me my speed fix 😁

Maybe a little more bow weight would stop the problem , my Spearfish used to do that all I did was put lipo length ways and it stopped , but yeah if your happy with the bigger being the faster then go for it 😊

here is my Fireboat after extensive testing of motors, batteries and props. Full details in "power set up".
Its about to have a gearbox fitted, this should enable me to fit a larger prop, and get longer run times, hopfully!

46 inch Crash Tender rescued from E-bay. Currently in the process of total restoration and have had to scratch build the entire super structure. Have fitted a Merco 61 engine with tuned pipe (the noise is awesome).
Have gone for it with the radio control- - employing a Robbe F14 plus an extra 8 channel module with decoder. So far extra controls are : each monitor (scratch built using brass pipe & sheet) left & right (using Robbe pulley set to give me 270 degrees travel), two Irvine water pumps, (real car) hooter, winch (using gearbox from Maplins) and movement for jib and search light.

John called this model "Nancy Dancer". it started of with plans from 'Nexus Plans Service' for Vic Smeed's 'Vivacity'. John used the hull only plans and created everything else himself. it ended up LOA 49" with a beam of 17". With the 12VDC battery the weight came to 23 1/2#.
Because of his basic 'Sedan Cruiser' he designed all the mechanicals and electricals beneath the main cabin floor, including the battery. There was quite a bit of detail put into the main cabin - unfortunately not shown in the photos - including a galley, eating area, furniture and the helmsman's station. The scale is 1" = 1ft.
This hull is plank on frame using 1/8" pine planks. Below the waterline there's epoxy & glass and above there is just epoxy. All the brightwork, cabin housing & decks is natural Cherry with a clear urethane finish.
The power is a Dumas 12VDC motor with a mechanical speed control. The bottom photo shows that he added a 2:1 gearbox to the motor and ran it in reverse to increase the prop RPMs. He also included a constant running fan to cool the motor due to the confinement of the space.
The single propellor is 2" - 2 pitch - 3 bladed bronze. As on all his models he used a 2 channel JR XR2 75 mhz.

The boat has no name as yet, it is scrach bult from two photos. I found in a loft as usual. it is about 25/30 years old, she is powered by a darke horse 785 turbo with a 2.5 to 1 gearbox and two 9.6 volt 3700maH NiMH bateries and a 50mm 3 bladed prop, sailed at our local lake.
The boat is far from finished and is not to scale as you can see, but for a first time build it looks pritty fair out on the water. Just one last word, many thanks to all the members of the forum for all your help.bit of a muck here lads the photos were in the loft,the hull I bought for £30.and every thing else is scratch built.
