I received an email and subsequently purchased the Beta 4.0 release of the Menards FP9. I have a Beta 1.0 that I was disappointed with on the operational side, but it is still a nice-looking model with potential for improving on a future project.
The Beta 4.0 version hopefully will resolve many of the operational issues I had with the original one and the bonus is that it comes with an unpowered B unit. The other difference is this one is in the late "Blue Bonet" Blue and Silver paint scheme that some of the ATSF F7s and F9s wore later in their career.
I will be reporting my feedback directly to Menards as I did with my original purchase.
Anyone interested can find a link to the Menards FP9 Beta 4.0 here.
