OK, for the purpose of clarity, the two mods you mentioned were done by a gent going by the nickname 'Hairball' (and sometimes 'fursphere'). And it is an E-MAXX tranny (not a T-MAXX tranny).
http://www.theshreves.com/rc_stuff is my site.
http://www.txt1.net is hosted on my server and I bought the domain name, but we work on it collectively.
Just want to make sure I am not getting credit for his killer mods
