Found these (you may have seen them) before.  They come in various RPM choices from 30 rpm up.....  I recently found the 1000 rpm types.  Useful for various projects.  Coupled with the LED dimmer that allows 25%  50% and 100% speed operation plus on/off..could be a cheapo driver mechanism for a small model.....

It says 12v but it operates from 6v/9v quite happily.....

I put one in my 35n2 rail truck (BPRC).  I think the motor was like 120rpm.  I used a Bachmann Brill Trolley with the original motor removed since it had such a high starting voltage.  The power truck had some reduction gears, and with the micro-motor the rail truck crawls at some 4mph.  You can literally count the ties!

They're tiny so you can fit them just about anywhere, and they're cheap at only a few dollars on flea bay.

I'm ordering a few more, with higher rpm, to install in some HO scale Plymouths that I plan on converting to 35n2.

As for "proportional" speed control, if the truck runs about 4 to 5 MPH, you shouldn't need fancy control. Just backaard & forrard. Cheap r/c for sure! Also consider old Class A Climax locos, they had 2 gears so they must have leaped into motion when engaged. Another cheapy control probably!

Woodie

Here's the 'inversion motor' type, in the Mysterious Moose Mountain Ford Railtruck. :old dude:





Very compact & fits nicely between the frame of this 1:35 scale Ford chassis.





16.5mm gauge & final drive provided by our patent ;) rubber chain-drive !



:moose:

Si,

I have some extra wheels that will work for another rail truck.  Also picked up some pulleys, gears, and 'rubber' chain drive.  I just need another round tuit.

These gears fit the micro motors perfectly:

Hi Michael :wave:



:bow: :bow: :bow: :bow: :bow:



Now THAT is exactly the kinda gear I wanted, but couldn't find !

THANKS !!





I have 1 of the 'regular' straight gearbox-motors, like William Posted, as well as the 'inversion motor'.



The same guy also has this set as well ...

MORE COOL GEARS - Inc. other useful types

They look like this ...





He also seems to have nylon motor-mounts, for the 'straight' N20 motors.

Bit chunky for me, but could be useful.





Pimp my Plymouth ! :pimp:



:brill:  :!:  :old dude: 



Si.

Didn't see those motor mounts.  But then I wasn't really looking for them.  I'll have to order a few.

http://www.ebay.com/itm/2pcs-Blue-Block-N20-Motor-Fixed-Frame-Mount-Bracket-For-Aircraft-Helicopter-/371455231031?hash=item567c750437:g:zakAAOSwuMFUgCBs


These are things one wants to keep handy in their parts box.  They only cost a buck or two, and it's nice to have them on hand when that creative mood strikes.

What would be really useful ...

... would be a 3mm shaft D-Hole worm-gear !


I see loads of 2mm worm-gears, but can't find any like ^^ above.

There isn't enough placky to drill out the 2mm ones either.


???


Some motor dimensions, which might be of interest.











These units are available with extra-long shafts as well.

They are also available with a long threaded 'lead-screw' type shaft.



:brill:



Si.



Here's another guy with the small 3mm D-Hole shaft gears.

MORE gears ... LESS dough !

White nylon this time & 10x pieces, for less dough than 5x pieces. :)

These placky pulleys could be of interest.

They are a push-fit on a 'standard' 16.5mm gauge, 2mm dia. wheelset-axle.


Packs O' Placky Pulleys             :thumb:





Slightly BRIGHT COLOUR ! :shocked:

Perhaps something is available in black or white as well ?
