Using TWIN MOTORS in model boats  -  Dave Milbourn
But I donít understand Electronics! - Dave Milbourn

  If you still haven't built your first model boat,  this section may seem a  little  boring.  It's a two part reference guide to electric and IC boats,  the equipment,  their installation, use and control. Read this section now  and  save  yourself  time and money by building correctly first  time  and  preventing  common mistakes.  Don't be too worried if you don't understand  all the terms and expressions, as long you understand the basics, the rest  will become clearer as you use the equipment for yourself.  The convention  used in this and the following articles will be MOTORS are electric motors  and ENGINES are Internal Combustion engines, IC for short.   

   There are various ways of powering your sports boat eg,  electric, diesel,  steam,  two  and four stroke IC engines,  even rocket power has been tried  (but  highly illegal),  the two most popular forms are two stroke (or glow  plug)  IC engines and electric motors.  IC engines are used mainly in fast  models as they will continue to run at full power until the fuel runs out.  Electric  motors are used in all aspects of boat modelling from  submarines  to  drag  race boats.  Electric motors are much more controllable than  IC  engines ie, they can be made to run from stop to full speed, re-started at  will  and can run backwards.  Electric motors are also generally easier to  install,  run,  maintain than IC engines and are cleaner too.  We'll cover  electric boats now and go on to IC engines in a following article.
