Welcome Aboard!
There is a veritable cornucopia of information here but finding it sometimes can be overwhelming with the built in search function. There is a better search approach using Google. if you premise your Google search with site:450bushmaster.net
search term(s) you will be able to tighten up the search. IE "site:450bushmaster.net side charging" will return a lot of threads where they are discussed such as
This One. There are reference models cited in that thread along personal experience testimony and vendor links.
I too am charmed by side chargers but have a lot of other project "irons in the fire", so I have yet to find my wallet.
