Otto, remember to give @Lemosteam your pennsy leftovers! It convinces him to make cool santa fe stuff that we need!Drasko
I just bought a new BLI M1. It is a stunning looking model, and the variety of the Paragon 3 decoder sounds is amazing. Very impressive.But, out of the box, in DCC, I find its running qualities marginal. Not terrible, but uneven. Even if I can get beyond the multiple cutouts (and I assume this will take some time till the blackened wheels wear off and perhaps some more weight is added to the tender) the loco does not run smoothly at any speed. At low speed, it emits a weird whine (with the sound off) and at medium speed, it still exhibits an annoying unevenness. I tried it on DC and it gets worse. I also tried turning off the BEMF and the results were terrible, very uneven running. My conclusion is that the BEMF helps overcome some mechanical issue, but whatever that is, it's not obvious to me.Again, this is not a bad running loco, with BEMF on, just marginal. Did I get a lemon, or are they all like this and I was expecting too much? I need to decide whether to send it back or try to work on it...Otto K.
Narrowminded, if you want to be messing around with the M1, you might want to take the decoder out of the equation (bypass it), because even in DC mode, the motor is still driven by the decoder's PWM motor driver. Run it as a straight-DC loco. That will show you which are the real mechanical issues.
I'm thinking to buy the BLI M1 but reading this I now wonder if others are find issues with this loco and if so what concerns should I have.Rick
