Picked up #1361 and #3750 from Palmer Hobbies today. Put both on the test track sweet!
Got them home put 3750 on my test oval fired up the DCC system and she was off and running, did a few laps trying out all the whistles and bell (literally). Maybe sound isn't that bad. Tweeted the speed curve to give her a 7th top speed, but it's going to need more tweaking as it breaks in.
Now #1361 has a slightly different first lap, down the straight fine, into the first right curve and she stops dead, light on, whistle & bell OK, but no go. Try reverse smooth as silk, reverse into the curve still smooth. Stop & start forward down the straight fine into the curve dead again. After a few minutes I found the problem, the main rod is hitting the pin, and binding. A few LIGHT swipes with a file on the pin and bottom edge of the rod and pressing in the pin, All is good now.
ALL in all these are great locos. This may explain the thrown rod reported earlier.
