You may get the sync sounds but since only one smoke unit I’ll bet you won’t get the sync smoke. Hopefully a video with the fixed sound will help people decide on sync sound or sync smoke. I would be happy with either if I could own one.
First of the smoke stack do not operate independently on the real challenger so not sure what your point is with sync smoke. I have the vision line Big Boy I wish I could turn off that feature because it is not realistic. The fact that people are happy to own it with the wrong sounds is exactly why there was no post from Lionel stating outright they would fix them. Not sure how people can drop this kind of cash and not push the manufacturer to fix their mistakes. Tolerance is only acceptable when it does not affect my wallet.
