While surfing for an answer to MDC's 4-6-0 & 2-6-0 models as to there prototype I ran across a very interesting 2 page thread. The second page is the most interesting with some interesting discussion on motors by poster "fwrite".

Carefully read the third to last post on page two and learn about cogging in a DC motor.

If so, what did you use?

I would like to mount mine on the back of my plywood fascia so that a connector is accessible form the front of the fascia, but am a loss as to what to use.

EDIT: Solved! - I posted how I did it (with pictures) here:

Hello,

Below is my first layout with N scale Unitrack. The point of contention is with with power being lost when I change either switch ( LH turn 20-207 / RH turn 20-208) by hand, and bring the train on the inside half loop. I've checked the track with a volt meter and sure enough it looks like the power is gone. 

I only want to run one engine at a time until I get the hang of this, so there are no isolation joints to the best of my knowledge and I think the switches are set to live-frog.

Any help would be appreciated.

I tend to be of the school that solders power feeders to every track segment. Given this, what I'm curious what purpose is served by soldering rail joiners?

I understand that their are situations in curves where flex track ends may not want to follow the curve and soldering helps the track conform. That makes sense to me. But what other rationale would their be for soldering the joiners?

Thanks!
