PS3 first impressions

Send the unit back to MTH.  This is the second instance Ive heard on the forum about a PS3 smoke unit melting the shell.  The other instance was SIRT and his LIRR RS-1.  Seems to be a design flaw.

I agree with Sunrise, I would not accept that the smoke unit melted the shell, I'd get a replacement.

For sure it's a design flaw.  I caught it early enough and it's hardly noticeable.  To send it to MTH for a new shell which more than likely they don't have and more than likely due to the design flaw would happen again in my opinion is not worth it.

Gary,

It might be worth a phone call to discuss the situation.

If this is, indeed, a design issue, then MTH may be working on a resolution. Regardless, it would  be good to know MTH's thoughts on the matter.

As others have suggested, definitely contact MTH.  Do not settle for short-term solutions such as turning down the smoke level, etc.  You deserve to have a product that works as it's intended to work.

I'll give them a buzz and talk to them at the next Train show.  I'm sure the Aluminum tape will prevent any future melting.  For some odd reason they did not place the output of the smoke unit directly under the stack.  It's off set by a half a inch with a scope/chamber to get the smoke to the stack and the fluid to the smoke unit.  Directly under the output of the smoke unit is where the melting has accrued.  MTH could of turned the smoke unit 180 deg in place and would not have needed that scope.
