Sorry I never got back to you. Just plain forgot. My Flyer Piper gets better every time I run it. Seems to have needed a lot of break in time. My 1835 has been nice right out of the box, once oiled etc. I do not care for the push-pull activation on the Flyer reverse units. They like to pop out of position a lot. I never use the reverse, so someday I'll zip tie it in forward and leave it. When the layout is done, I'll try and run it more being as I will have an extra loop. On my O gauge, I haves a Blue Streak, a Flying Yankee, the Lake Shore Ltd, a green City of Denver and a Red Comet that are traditional. All have been fine except the Red Comet. Early self destruct on the commutator and they had no parts for it. Became a paper weight for a year or so until I sent it off to Dennis Waldren for repair. He rummaged through a lot of old original commutators until he found one that would work. Been fine ever since.
