What are the chances of Bachmann ever releasing an HO scale engine with dynamic smoke? For those that don't know the difference between a smoke generator and dynamic smoke here are two videos: http://www.reynaulds.com/km1.aspx. I know of one German company that is supposed to come out with an HO scale engine with dynamic smoke either late this year or early next year.
It is most likely pretty far off if it ever happens, around 30 years or never.
Having viewed the videos and checked the scale size and looked at the list prices for the equipment , I would say : Ain't gonna happen . Those are large scale engines and $4000+ a pop is not going to fly under current economic conditions . To reduce the engineering to HO scale is going to be an expensive proposition . Besides which the fluid is $59.95 a liter. Just my opinion. John II
