Yes winter time is cold so heat shouldnt be a problem. and as far as ebay goes all you gotta do is start searching for some good sized nitro or better yet big gassers and start looking at radio boxes (big one are nice) I use the kyosho twinnforce esc box its plenty big. In the past I used to slide condems over my brushed motors in winter to keep the brushes from getting the clap...oops I mean getting wet.
