How is Scale PS3 Steam Conventional Performance?

I know that Lee Willis has a ton of PS/3 stuff, and he's exclusively conventional.  He comments on how well it run in conventional, so I suspect you won't be unhappy with the performance.  I've run a couple of them in conventional for testing here, and they seem to do just fine, but I haven't done exhaustive testing.

I used to be  a big MTH guy, plus I'm a steam guy.

I refuse to purchase MTH PS3 steamers as a conventional operator. The "lock up" syndrome when stopping is not acceptable to me. MTH has said it has "always" been an issue going back to the PS1 days. Fake news. I have a few very early PS3 steamers that were fine as are many older PS2 steamers - they will very gradually coast to a stop in conventional. This issue started with a 2014 produced engine and they all have it. MTH has told me "everyone uses DCS so it isn't worth it to us to fix it". As a result, it isn't worth it to me to be a customer. I unfortunately discovered this with an MTH Railking PS3 Mikado. I had issues with the train derailing, gearbox slipping, traction tires coming off, etc. I don't run them hard either but the sudden lock up of the drive train now common with PS3 steam, I believe, was a factor.

Don't even get me started on that wireless drawbar. Quite frankly, my displeasure with PS3 steamers got me into buying Lionel Legacy steam. I still purchase PS3 diesels (I bought a new SD40-2 yesterday) which have the "lock up" problem only when the smoke is on. As I don't run smoke in diesels, it isn't an issue to me.
