n scale challenger

i just got one of these and i really like it. i have a question about the two sets of drivers. mine are in sync. i thought i saw one on you tube that was’nt. arent both sets driven by a driveshaft? if so, i wouldnt think it could be changed. just curious. thanks

I would guess the loco gets what it gets when the drive shaft is dropped into place. If they are in sync they will stay that way, If out of sync they will stay in the same relative out-of-sync position.

The synchronization certainly can be changed, I just don’t know how hard it would be because you would have to partly disassemble the locomotive. I have a Challenger, but it came with the drivers unsynchronised, so I left it alone. I do have one of the first run Life-Like 2-8-8-2’s that had the drivers synchronised and I adjusted them. I don’t remember what I had to do, but I do remember that it was not hard.
