Those were the line drawings I was speaking of from the book in the other thread. I didn't suggest them because you wanted blueprints, but if they work for you...

I used the Tamiya box
https://www.tamiyausa.com/product/it...oduct-id=70097 (and so have a few others) 70097. It has a 3 position axle setting and is rated for the type of electronics we use. I picked one up from eBay very inexpensively.
