I did, thanks, and for the benefit of the Hot Wheels fans I am posting responses here and hope I might get some more guidance on the "upper" under magnet sticking point.

upper playing field issue
I've heard of a potential ball hangup here, but unfortunately I'm not sure of the recommended solution... my game is a very early prototype (doesn't even have any art, just plain wood) and I believe the placement of posts on my game is slightly different from production machines. I've never had a ball stuck there that couldn't be freed with a modest nudge. Suggest submitting a ticket asking for help. pinball2020 comment: ( I have reached out to Dave to see if he has any insight from seeing the pictures posted).
right side issue
Underneath the playfield, the drop target assembly has a screw that allows you to adjust the height of the target. You can give it a very tiny tweak to adjust the height so the top of the target is perfectly flush with the playfield surface so the ball won't get caught up there. This is likely to be a very fine-tune sort of thing, since of course if you raise it too much, it may obstruct the ball's path to the saucer.
As always, you guys rock.
And for the other Hot Wheels fans:
* Yes the pads are getting banged up - try changing the flipper strength down from 25 to 20. It has helped and I may need to test tweak them to 22 or 23 but I get less richochets off the glass, looks like less pad wear, less Hot Wheel car kewpie doll knockdowns over the ramp on the right from flying balls and as a bonus - I FINALLY successfully beat the gorilla with controlling my shots. Stay tuned and keep tweaking and post what works for you so we can experiment as well.
Hope the other Hot Wheels fans are having fun too.
