Hello from the owner of the Lorna doone 2

[Lornadoone2]

Hello just thought i should say hi.
i am new to the paddler community and am restoring a 40yr old r/c model of the Lorna Doone2 she is just in need of the power plant (electric) to go in a graupner bb720 torque

LD2...here is the same message I posted on Model Mayhem for you today....PeeWee & Talisman [Kim] also posted a response to you......... ......

mmmmmmmmmmmmmmm according to GOOGLE, the 720BB = 4100 RPM no load......is a bb720 and a 720BB the same item?

Speed 720 BB TORQUE SMC-M-6372
Nominal Voltage 12.0v - Voltage Range 6.0 - 13v - No load RPM 4,100 - No Load Current 0.75 A - Current @ Max Efficiency 3.0 A - Stalled Current 13A - Max Efficiency 75% - Case length mm 72.0 - Case dia. mm 44.5 - Free shaft length mm 6.5 - Shaft Dia. mm 5.00 - Weight (g)380

Optimal paddle shaft speed for a model paddler of 5' is in the order of 150 RPM....with the ability to reduce that further with a speed controller....so if a bb720= a 720BB then you would need a reduction of say 25:1

Log in & have a look @ our paddleducks.uk WEB site .........you will find many references to this & discussions on common/single shaft drive as very few paddlers used independent drive for each wheel.... Derek

Welcome to Paddleducks, it's always good to see someone restoring an older model to its former glory, and putting it back into use!

welcome to Paddleducks, very good looking ship you have, would that be the Lorna Doon which was previously Queen of Kent and originally HMS Atherstone? - often thought about building one of those as a minesweeper....

That is the one i think its one of the nicer vessels to ply the south coast she really just needs the motor and drive system fitting belt drive maybe?
