Thank you for adding your valuable insight to this issue...
In 30 years, this is the ONE and ONLY major problem I've had with an AM locomotive and I have quite a few of them in both Scale and HiRail, to say nothing about my fleet of freight and passenger cars.
I'll still recommend AM products to anyone entering S.
