Steam engine/plant to RC-scalemodel side wheel paddler

[olynes]

Hello!
I feel very lucky to have found this site.
I am going to scratch build a RC-controlled, live steam scale model of an old Norwegian side wheeled steamboat: http://www.skibladner.no  
I want it to be at least 5 feet long. The paddle wheels need to be fixed to the crank-shaft on the engine.
Have anyone made anything similar?
And if so, what kind of steam engine/plant can I use that is strong enough (and not to heavy) to run the boat when having form 0 to 40 rpm?  
I would like to be able to control speed, forward/backward and have a steam whistle.  I have seen the Cheddar ABC control.
Can this be connected to an electric boiler feed pump?

Most grateful for any answer!!

hi Olynes - I am familiar with the Cheddar Steam model site, their engines & their amazing ABC system, but have not heard of an electric driven model boiler feed pump - we must remember that the BFP must be capable of exceeding the boiler pressure so as to get water into the pressurised chamber etc

You may wish to check the outgoing PD Yahoo site & read about the excellent model of PT Relient which has twin Cheddar steam engines

Hi Derek,
Thank you for your answer.
I was thinking of rebuilding the ABC system a bit, so that the pulse could trig an el.motor-system that is powering a manual feedpump. When a timer system is connected to the power-side of the motor and is adjusted correctly it should feed the boiler corect, too.
I just wondered if someone had tried this.  
I will the check the outgoing PD Yahoo site.
