Blackstone K-27

G'Day All,

I was wondering if anyone has a Blackstone K-27, with OEM Tsunami sound.

I wanted to know if the chuff rate was correctly synchronized to the wheel movement at different speeds & loads. This being a common problem with OEM tsunami products.

I have one! All seems well with the synchronization, when you open up the locomotive, you can see the shaft sticks out both sides of the motor, one side to the gearbox, the other to the flywheel. The flywheel side has a disk with a bunch of holes around the perimeter, in front of a photoresistor, this produces the synchronized chuff.

Thanks Jake,

That's exhaust steam to my ears  - just what I wanted to hear.

I assume the detail & running characteristics are good?
