twin robbe direckt motors with brass 40mm prop's. 12v battery 10 a/hr.

Had a full refurb but still need the window frames making when I can get round to it . Goes really well with a Graupner 700BB Neodym on 14.4 volts. Still trying to find the right prop, but pretty close now to getting it right . Aim to getting it up to 19.2 volt
Should really fly then.

Lesro Sportsman kit, wood sports fishing boat 33'' in length, weight about 8lb. MFA 850 on 12v (10 NiMHcells 3.5ah) MTroniks 40amp esc, X50 prop. Built by Ian Gardner.
March 2010. I am now using 12 cells and a Graupner speed controller. I added watercooling too and the boat goes noticeably faster- but melted a fuse holder on first outing so I need to upgrade some of the wiring. There was also a bit of prop aerating on turns so might reduce the prop size.
The last photo is with increased voltage.

shear water motor cruiser I made from scratch plank on frame looks well in the water with the added motor and prop give it an edge turning and coming back up the lake no ballast inside the boat its all built in the keel navagation lights work and a small table with a map for someone steering thanks russell

this is my aerokit fire boat 46 inch fitted with a 600 motor 3 bladed prop 55 mm and a 12v 12 amp battery was fitted with a petrol motor when I got her for A£35.. all the top has been rebuilt the 2fire hygents work very good 2 mrtrs of water either side all lights work a good turn of speed but I can get 2 1/2 hrs on the lake the two men are not right but look ok for 10 p each at car boot gordon

I have rebuilt this from a damaged ex IC model. Borrowed a plan from a club member and managed to reconstruct the missing bits. Originally used a fast electric car type brush motor with 7.2 v nicads. Worked ok but nothing spectacular. Recently ventured into brushless and LiPo. Tried an inrunner but ran far to hot and not veryt fast. Changed to an Outrunner (mork torky apparently) and nearly took off! (it is a seaplane tender but should stay on the water!) The LiPo is 11.1v 2800MaH. I use a Graupner Ultramat 16 charger, don't use other than a dedicated LiPo charger and ESC. Battery misuse can result in pyrotechnics, so beware. initialyy tried a two blade racing prop but have changed this to a 29mm 3 blade brass prop to slow down the speed. I have also added more lead and will advise the final weight once I have tried the model on water. I sail with Crewe and District MBC at Boundary Park, Nr Knutsford in Cheshire.

HI All,
This is an update,weather seemed ok so tried her out,very Impressed,got right up on the plane.Handling not that good think a bigger rudder is needed.
Running an 850 torpedo motor on 12volt battery.
Only problem was a leak,water running up prop tube so have removed and re-greased ready to try again.
Fire monitors missing hoping somebody can help.

This boat was scratch built from Harold Underhill plans, available still from Brown,Son and Ferguson. The hull was mahogany on 6mm ply frames. The engine was a Caton from Maxwell Hemmens supplied bya gas-fired Cheddar Puffin boiler. The propeller was a two inch four bladed brass job from Rivabo I think. The displacement of the boat is 25lb- a bit of a lump to carry to the water but it does work well once in the water. She has now been converted to electric using a MFA geared 540 type motor witha 7.5ah lead acid gel cell. Looking again at this video I begin to wish I had left it as steam but there is something to be said for 'switch on and go'.
I started building the boat in the mid nineties and it has now had a repaint- it always been a favourite. This video was taken in the early noughties at Crealy in Exeter.

HI all. This is an, RAF Fire Tender 32" that was given to me 30+ years ago by a friend who was going to scrap it. it's been stored in my garage loft all this time. I am about to start the restoration of the boat but havn't done any modelling since I was a youngster.
It has no running gear but was originally powered by a nitro engine, I am hoping to convert it to electric power, the problem is I have no idea what type of motor to use or what length prop tube or prop sahft is required, I don't have any drawings or information about the boat. I am presently cleaning and rubbing the panels down so that I can re glue most of the joints as thay are mostly starting to come loose.
Will post some more photos as I progress.

Aerokits Solent Kit bought as a present in the 70's. Worked on it on and off until 2000 when I finally made a maiden voyage. Two Buhler motors driving Prop Shop props with Bobs board and 12v 17Ah SLA. Radar works. Realistic scale speed and looks great on the water. To turn I have used micro switches to cut out one motor on full rudder. The large keel was causing the model to cease turning with both props turning. I sail with Crewe MBC at Boundary Park Lake. Oct 09. Have now found out that the cabin door on my model was only fitted to the last three builds 48-014,-015 and -016. At least I can give her a name once I have decided which to use.

I have just acquired this model via a swap for my Al Khubar Tug. I am in the process of deciding which actual lifeboat to model. This is based on the Metcalfe Moulding and is 1/12 scale at 52". in its present condition it has two Buhler motors and some early ESC's. Power is from a 12v 7Ahr dry cell. it looks great on the water but duration is not that great. I am preparing for a complete rebuild including re-prop shafting and different motors. I may rebuild the cabin as the moulding I have was only used on 5 Arun's and I may not be able to get enough details. I have sourced a plan and have detail pictures for City of Glasgow 111 (needs new cabin). Awaiting a book "RNLI Motor Lifeboats" from Amazon to help me progress. The present crew will have to be relocated to a 16th scale model! if I remember to take photos I will post a build blog.

Thanks to all those that made suggestions about making the Suction Hoses, here are my efforts. The boat looks OK now thought there is much to do still. I am using two Johnson drill motors in paralell with one 50 amp ESC & 20A fuses in each motor + supply lead, all running on 8.4V NiMhi. the current props are 40 X 21 three blade. The boat is fast enough but battery life is short and the battery is very hot after the end of the run. I water cooled the motors and ESC. I will try some smaller props and 7,2V to see if there is an Improvement.
