I have another North London locomotive project currently scattered around a box. It is fitted with a High Level RoadRunner+, also 54:1 but with a drive stretcher and, of interest here, a Mashima 1432 motor. Since the drive is the same on both gearboxes I was able to easily swap the motors and this produced a very smooth mechanism that I am quite happy with. viewtopic.php?f=128&t=5075
I would be very interested in any thoughts about the relative merits of different motors. I am currently running a 1220 on my Barney with a 40:1 gear. Are certain motors known to run less smoothly than others. Do people have preferences and why? Also are there any moves afoot with gearbox manufacturers regarding matching with alternative motors to Mashima?
