Guys you are right! But I live in a New York City apartment and 036 is the best I can do. And while I agree that I might never see the problem at higher speeds or wider curves, I bought this engine BECAUSE it is scale and yet can run on O36. Add to this the fact that the other engine in the set has run on the same track for hours and hours and never once experienced the problem. And perhaps my stongest evidence why this COULD be able to work is I have the even larger E8 AA set from 2017 which has run on the same track flawlessly for more than a year. And, yes, I am a bit of a slow speed freak, that's what I love about Legacy, but that E8 crawls around at 1.5 SMH all day long without a complaint.
Yes, I am probably asking a lot out of this engine. However...it did cost $1000.00!!!
