I would like some higher ratio boxes than the mato steel bearing ones I have, also brass would be nice but guess they are gone.
The mato boxes screw into the mato hull from the top down, so the screw heads have to be accessible from the top through the box.
Will the taigen sherman gear boxes allow for screws to be inserted from the top... ok that's a dumb question because it all depends on where the screws go.
I know the Tamiya boxes have super tight clearance between the gears and the bottom plate so don't think they will work for top down screws. But really it seems like I will just have to get gear boxes sent to me and see if I can drill new holes in the bottom in the places I need to insert screws.
Talk about trial and error.
Really though, I would recommend against the MAto steel gear ball bearing boxes due to the total crap that they miss in QC. I should have sent that bad one back but didn't know it was bad until now.
Your comment about the way the ratios are described is accurate and has been hashed on this forum a few times. The general consensus has been to refer to them by the number of reduction shafts or gear sets. There are only so many options; so, it works.
Not sure what you mean about the "top down" screws. All of them that I know of, bolt in by inserting the screws through the bottom of the gearbox plate and into the lower hull. They all attach from the inside so that you can have a smooth bottom to the lower hull and add some detailing to the bottom of the lower hull.
