My concern with valve gear is simply ... is the fault on the loco revied just an isolated example and others are correct ... or are all the locos faulty in their assembly
On the issue of kitbashing the loco ... it should be kept in mind that the prototype as proposed is a tiny loco. I do not think that the loco would look scaled correctly with the saddle tanks removed unless the boiler were expanded. In that context the lack of supports and the sizing of the electronics etc should not be an issue. On the other hand if the bashed loco were to represent 1:24 scale then it would be a bigger issue. But is hard to fault the manufacturer for not taking that aspect into account.

Bachmann has a video of the 2-6-6-2 which includes several slow motion shots.

at about 2 minutes there is a good slow motion shot which shows the eccentrics. To me they appear to be working properly and working the same as the prototype video.

In the locomotive I have all 4 eccentrics are the same as in the video and the operation is very smooth.

The photo on the onetotwentypoint me blog shows a very funky eccentric

I am amazed that this locomotive would even operate for a single wheel recolution.

Both the locomotive I have and the one in the Bachmann video were likely assembled by more trained individuals then the typical production locomotive so one would expect fewer problems. Both of these locomotive do provide two examples of how Bachmann intended them to operate.

So if the operation in the video is wrong then they are all wrong. If the operation in the video is correct then the locomotive reviewed is likely an assembly problem which hopefully is an isolated one.
