my scratch built Brushless Sea Nymph run on 11.2 volts

My restored Aerokits Sea Queen with Brushless motor at Fleetwood on a very windy day

These two boats were refurbished by Kalamunda. The first is a Lesro Sportsman and the second a NorStar Wave Rider. The Sportsman has a Graupner 700 on 8.6v and the WaveRider a brushless motor. The on board camera was arranged by Kalamunda and other video shot by Ianed57. The water is at Crealy, Exeter, the home of Exeter and District Model Boat Club.

Found beached on e-bay and refurbished. Brushless motor running on 8.4 v. with Planet T5 2.4ghz radio. First trial at Goodrington, Paignton. 12 Mar 2010

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.
