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.

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.

success !! I have done it " my photos of my two boats . the one on the water is the 94 fireboat fitted with a 500 torpedo electric motor and a spectrum rx/tx works very well !! . The other is crash tender 93 under going a rebuild after being rescued on ebay . from a new member A prestney.

Fishing cruiser built from kit by Dumas- no longer available I believe. Powered by Graupner Speed 500 on 7.2 volts with MTroniks 15 amp ESC. Travels at brisk walking pace so not exciting, but nice to watch. Has a big boat feel even though only two feet long.
There's a video of Scoter on the water.

Scoter was built from a Dumas kit ordered from America. it is a planked hard-chine boat reperesenting an East Coast fishing cruiser, She is 2 feet long with a Graupner Speed 500 motor running on 7.2 volts through an MTroniks 10A ESC. The crew are from George Turner Models, 1:12 scale resin figures.

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.

A friend, found this boat in a junk shop, Unloved and done up as a cabin cruiser.and asked me if I could rescue if for him. So I did, id just like to thank everyone on the site for posting there pictures and information as it made the job a whole lot easier for me.

Its an RAF Seaplane tender, a few months old now, powered by a raboesch 400 motor on 7.2V

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!!

This is my Sea Hornet which was rescued from Ebay see photo 1. Gray (Froggyt996) recognised it as a Sea Hornet even with the hideous cabin attched which the prvious owner had made. Also see the propshaft angle in photo 1 - would this have ever worked? Gray again restored this for me, I wanted a mahogany boat which looked like an italian speedboat and this is what he did for me see photo 2. Photo 3 sees the Sea Hornet on the sea at Southsea just after the start of the Round Britain Race in 2008. The receiver battery failed and a very nice Lifeboat Man from Southsea happened to be watching me run the boat and rescued it when it stopped running. it was put in dry dock over this winter to be tidied up again after a couple of years constant use and photo 4 sees it with its 2 new screens, re-varnished and 2 new rubbing strake. it is powered by 2 Graupner Speed 600 motors, a Ripmax sea sprint watercooled speed controller and 2 x 3 blade prop shop props on 2 x light weight shafts. it is also filled with bouyancy foam it case the inevitable happens which makes it quite heavy. it is ran on 2 x 8.4 volts nicad sticks and gives me a running time of approx. 20 minutes with quite a good turn of speed.

This is my Aerokits Solent Class Lifeboat that was rescued from Ebay as a wreck see photo's 1 & 2. This was then lovingly restored for me by Gray (Froggyt996). First he had to skin one third of the hull as only two thirds had been skinned. He then had to use copious amounts of filler to make the hull its correct shape see photo 3, instead of the stepped hull as per the original Aerokits build. He then had to put the superstructure together as it had fell apart whilst being posted to us as it had been put together with a hot glue gun yuk!!!!!! Next started the painting as shown in photo 4. Please see my next post for the next stages of its rebuild.
