Here is my restoration (conversion) of a US Coastguard vessel into the RNLI Waveney Class Lifeboat. I think you will agree that it looks better in its new livery. Have put in two jp power 400 motors along with mtroniks auto tune 20 amp esc and am using 7.4V lipo batteries. First try out went very well, but that was the bath, will try her out on water in couple of days

Aerokit Fireboat 34"
Boat was given to me in poor condition approx 30 years ago, no running gear and most fittings missing or broken, originally powered with IC motor.
I have installed a 43A 700KV Outrunner Brushless motor, Model No : XYH42-50 and a Hobbywing Seaking 60W / Reverse Program Brushless ESC bought from Giantcod, powered by a 3 cell 2200 mAh Lipo battery runtime 15 to 18min, the prop is a 42.5mm 2 blade racing prop. I am well pleased with the performance of the boat.
I belong and sail at the Hartsholme Electric Model Boat Club, Lincoln.

Here is my take on a torpedo boat, YES I know why has it got a rocket launcher on rear, well I wanted something that was different from the rest with my own signature on it. it is powered by a .60 size electric motor 120amp esc, two 5000 3 series lipos. Only allowed to have it going on 1/4 power cause of speeed limit on lake. The hull was originally a 48" deep vee hull but added perkasa superstructure to it.

Here is my Aerokits Sea Urchin on its first outing in July 2010 at Fleetwood. Running on a 7.2v Lipo on a small outrunner motor costing less the £5.00 from Giantcod.co.uk.

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.

Here's a video of my boat running at Vienese evening, powered by a brushless motor and LiPo battery.
