Here are a couple of non “On2” scale websites that may be useful to viewers interested in improving locomotive suspension and performance;-
This is a UK site which presents an overview of the work done by various individuals and groups on advanced but practical locomotive suspension methods used by the UK Fine Scale and Prototype based groups primarily in 4mm scale. It’s quite a site, with a lot of content, and probably more than most modellers will ever need or feel comfortable with. The physical size of these models is close to Maine On2, and many commercially available parts (such as motors, gearboxes, axles and hornblocks etc.) can be used.
This is a link to Jeff Bissonette’s blog where he posts mainly about his work on making chassis’s for various locomotives in the smaller scales such as Sn2, HOn3, HOn2 and OO9. There is a wealth of practical information (and inspiration I hope!) in the older posts, much of it applying the principles of the site above. Jeff’s comments about Sn2 loco’s and their performance and how he improved these are worth reading for their close similarity with products offered commercially in On2.
Enjoy if you visit.
