I am pleased to report that, having fitted a Mitsumi motor to a High Level 60:1 Loadhauler gearbox, and mounted this combination in the frames of a Midland 3F, I have what I believe to be the sweetest-running chassis that I have ever built. (.... and that's quite a few)!
I get the impression that these Mitsumi motors are lower-revving than Mashima motors, but they have plenty of torque and are beautifully smooth-running and quiet.
Using one of my trusty H&M Walkabout controllers, the top speed of this 0-6-0 slogger is as close to that of the prototype as I could wish - ie. a sprightly but not unseemly canter!!
This is ideal - I have the full range of the controller slider to drive the loco from a barely perceptible crawl to a realistic top speed.
The fitted fly-wheel gives a satisfying impression of momentum, even with a lightweight bare chassis.
So, I can with confidence recommend these Mitsumi motors.
I have taken the plunge and bought the remaining stock of motors - 215 units - and am offering them to list members at £7.00 each including UK P&P. (The equivalent Mashima motor is currently priced about £17.00 plus P&P.
I already have reservations for in excess of 50 motors, and when they're gone, they're gone !! (One potential customer has reserved 30 motors).
I normally confine my activities strictly to transfers, but these motors are just too good to let pass. I will publish purchasing arrangements when the motors are to hand, tested and packed. (I will be including two M2 fixing screws with each motor).
If you want one or more of these motors whilst they are available, PM me now to reserve your requirements.
