it seems people in new zeland are having problems with final gears. i just received my connie and its good i heard about the problems. the first thing i did was rip it apart and i found all of the gear box screws-gear box cover screws and mount screws very very loose. if i had run it only for an inch i would have destroide the drive train. who would be to blame?- me! as i know that quality controll at bachmann is out to lunch. the only way they can redeem thereselves is to no.1-ship replacement parts real fast for those that whant to fix the problems themselves no.2 offer free shipping both ways (fast) for those who dont want to clean up after bachmann workers. we will keep buying if this is the case. if not i will buy from another manufacturer.
