Yeap Pat. I have figured out many upgrade flywheel stripes over the years. A couple dozen?
I just use a starting guess, then rough math % of error to get closer, and then fine tune it. Not the best, but it works.
The motor you sent should work. SO I have to get a flywheel on the end to add the stripe tape to.
I actually did not think to use a Lionel one. So I will look into that.
