This is my first foray into brushless.I did spend a great deal of time on research before making a selection.I went this route because the choice of available brushed motors has diminished drastically with Graupner's and Robbe's troubles.720bb turbos would have been the easy choice,just try buy a pair new now
What I have found as regards brushless is the following;
Most cars use inrunners,most off the shelf motors are high revving,low torque.Great for fast electric boats,not ideal for tugs.
Outrunners have more torque than the above and to generalize more torque than the equivalent brushed motor of size and weight.T24 brushed motors from Mobile Marine Models would be great,but weigh over double that of my choice.There just isn't enough displacement in this model to allow me to fit them.
From other forums,I have learnt that speed controller selection is paramount for low rev control of these motors.Choice is limited for marine applications,I am opting for Mtronics G2s as they offer full forward and reverse control without a 'brake',common in ones for car applications.Many controllers are for aeroplanes,no reverse
.
This is a very scaled down synopsis of my research,There is more to it than just this,but don't want to run into pages.
Obviously the only proof is in the pudding as they say,however I am confident that I have made the correct choice,if anything,the model will have more torque than I will ever need.
Kind Regards
