Hi, folk's

I have been asked the question as to when do you use a speed motor and when to use a high torque motor

At the same time what is the benefit from geared motors.

Not knowing a lot about what motors for what boat's I seek your help so I can be sure to advise my customer

Would there be a general rule of thumb to what size motor is ideal for a certain size model od boat types


Thank's

Steve

 Hi Steve.
              my general thumb knowledge.
             
              High torque motor for
              Large tug, fishing trawler, cargo boat, liner  etc a large "scale model"  traveling at a medium walking pace.
               Prop. usually large brass course pitch slow turning. The model usually has a bit of displacenent to it  (ie a hernia job)
       
               The geared hecto and decaperm also fits this use for category.   

                A speed motor for
                the power boats, (some) cabin cruisers, fast elecrtics, patrol boats etc or small "scale models"   A light weight model  where
               the motor wont  complain (get very hot). 

                 prop usually 2 blade  plastic for fast boats or 3 blade plastic for the more scale type model

                motors can be geared up to increase their speed or down to reduce speed. 

                A geared fast motor will reduce the amps a bit that the motor will draw and give you a longer sailing time for a small
               reduction in speed.

                 I deally you look at the motor prop selection, to the type of model its for, and will the motor cope with the displacement
                the model has, to make it travel at a scale speed.
