Slower in DCC then in DC
#8
Hey Chris and guys, I just feel the loco should have a little more emmph! I guess I wasn't too clear about how the locomotive operates. When I built it I made sure the drive mechanism moved clear and freely. I was told to use a piece of glass and set the drive mechanism on it without motor installed and lift on side of the glass and see how the mechanism moves. Keep doing this until you see the mechanism move freely across the glass. It took a little while filing the burrs out but I eventually got the drive mechanism to glide freely across the glass. So I do not believe this is a mechanical problem. At the time I was still tossed up on what motor to put in it. The orginal DC-71 or a Helix Humper. I opted eventually for the Humper, hopefully to get a quieter motor. But I tried both motors in the mechanism, without a decoder, and the engine flew down the test track. After I installed an NCE D13SR decoder I could see a noticable speed/power difference. In the NCE manual for this decoder I do not see anything about back EMF but I do see information about setting kick rates. I'll have to give them a try. I believe I've tried these before but I do not recall the results. See this locomotive hasn't been on a layout since last year at my club's open house.(I had the same feeling about the E6 last year) Won't be able to really get into it till after the show though, which is this weekend.


Thanks, Mark Thumbsup
