I've got one of these that I'm superdetailing (Everything from firecracker antennas to P87 wheelsets!) and I have considered replacing the Athearn motor with something better. Anybody have any ideas? It's going to be used for probably a couple years on DC before I can get a DCC system. I saw a small Sagami motor at my LHS, but I'm afraid it may be too fast for such a locomotive, it was something like a 16x30 round can and turned 15k rpm at 12v. About $25, no flywheels, but the shop also had flywheels that looked like they'd fit. Is this motor ideal, or does anyone have a better idea?
