Brushless outrunners in tug
« on: September 08, 2021, 03:55:46 pm »

I have two ROXY C42-50-06 800kv that were intended to go into a 1/12th scale lifeboat but this may now not happen.
Would it be possible or difficult to install these into a single screw large tug by somehow coupling them together with a gearbox that would limit the speed of the motors ? They description of these motors says they are high torque.

It would be much easier to fit a single large brushed electric  motor than to run 2 outrunner brushless motors through a gearbox.

Probably no need to go to a big brushed motor, just use one of the brushless. With a kV rating of 800 it should turn a good sized prop. Need to limit the speed of the motor then either use a transmitter which allows you to change the end point of the throttle stick or just reduce the voltage of the battery, a 6V  will give you off load revs of 2400 and 12V 4800 revs off load.

Surely you meant 800rpm per volt Jim? 6x800 = 4800 etc


I agree one motor is plenty for a tug and I would use a Hobbywing Quicrun car ESC as they are so appropriate in my experience.
