I have wanted a Challenger for quite some time now(HO). I have been looking at the Ath Gen Challenger but have heard numerous complaints about the sound system and its operating problems (again same decoder). My question is if I replaced the sound/motor system with a Tsunami would I have a good running loco? I know it will sound good based on the two Tsunami steamers I already have. Another question: does the challenger come with traction tires or are they included extra. I really would find it embarrasing to have a 4-6-6-4 that had to have traction tires. But thats me. Thank you for any info.
